Customer Reviews

Very Efficient, very Flexible, Solid Power Supply The seller independently (and very much appreciated by me) shipped the AX1500i so that it arrived on April 5, several days early. I immediately unpacked it and put it to work.I had it running with 3 Gigabyte Geforce GTX 1070 cards for several days. That PSU is so efficient, it did not even bother to turn its fan on while providing about a total of 350 watts to the system. I also purchased 2 additional VGA power cables from Corsair so I can run the full complement of GPU cards that I want to run (9). I added 3 more Gigabyte Geforce GTX 1070s (now total of 6) and the PSU finally bothered to turn its fan on, but it has been running for almost a couple weeks without any problems at all. A few days ago, I added 2 more cards and I am still well below its rated output. Happily recommend to everybody who needs a high end PSU(but please don't bid the price up!). I do wish Corsair provided more VGA cables. I have yet to come across anybody who has an interest in TWO CPU cables, but that is what all the manufacturers provide. 5Zero RPM Fan and Accurate Power Consumption Readings are essential to overclockers and enthusiasts My first one came defective but Corsair quickly replaced it. Their Tech Support team is extremely competent and ready to help you. Finding their support phone number is a bit difficult but they have an extremely clear and intuitive interface for communicating with the support team through a personal case forum. You can post images, videos and text and submit it to the support team for review.My replacement worked perfectly. Make sure that you ONLY use the cables included with this PSU. Using other 6-pin cables to power your hard drives will severely damage them and cause other issues. They may continue to run but other issues will emerge later on. The Corsair Digital Link is fantastic for viewing how much power is being drawn from the outlet and how much power is being outputted to each component. The interface could use some enhancement but the program's "Power" tab is extremely well designed and user-friendly. According to my Kill-A-Watt meter the Digital Link is extremely accurate in measuring power drawn from the wall outlet. I was unable to confirm the internal outputs but assume they are reasonable accurate. The ZERO-RPM fan is a huge plus for those who run their computer in a bedroom or 24/7 since it will not produce noise when under normal or low load. Unless you are gaming or performing calculations, it is unlikely that the fan will spin up. By the way, 830 watts will power more than you think. You can see the load you are placing on the PSU in the Digital Link software. Even with an overclocked 4790 processor and two GTX 970s I never use more than half the PSU's capacity. 5Defective and Noisy, Only Somewhat Offset by Good Customer Service I purchased this PSU a little more than a year ago. Since that time I have had it replaced under warranty twice, and the saga is still not finished.Three of the AX1200i units I received were afflicted by a very noticeable (and patently unacceptable) coil whine. This manifested itself under load (i.e., when gaming) as a high-pitched squeal that was both maddening and disappointing. The PC into which I had built this PSU is otherwise extremely quiet (even with two ASUS STRIX Radeon R9 390X Overclocked 8 GB DDR5 512-bit DisplayPort HDMI 1.4a DVI-I Gaming Graphics Card). After completing the initial build, I noticed that under load, the PSU squealed quite a great deal. Thankfully, replacing the hard drive in my build with a Thermaltake Level 10 Titanium case is not exceptionally difficult and does not require the "open-heart surgery" that such an event might require in other cases. So, I contacted Corsair and arranged for an advance replacement (wherein you must provide a credit card to which a temporary charge is applied) so that I could get a replacement unit in advance of returning the defective unit.They promptly sent me the replacement unit and I returned the first unit to them.The second unit also squealed under load. It was a different pitch and responded to different loads (i.e., games), but was altogether too loud to tolerate (especially at this price point).Undeterred, I contacted Corsair. We repeated the process.This time, because stock was depleted, they kindly shipped me one directly from Asia. It squealed under load.To be clear, the squealing in all three units was not subtle. And it wasn't a function of me being finicky. It was the kind of sound anyone would notice.Unfortunately, at this point, the unit had gone out of stock (wasn't available on Amazon and Corsair no longer had any on hand). They offered to replace it with the larger AX1500i; however, that unit is too physically to large (long) for my case. So we agreed that I would wait until they received new stock of the AX1500i, and that I would live with the squealing until then. We further agreed that they would first ship my unit to their technical support where they would test the unit for coil whine, establishing that the unit was perfectly silent before shipping it to me.And so my multi-month wait began.Four days ago, the whining power supply (the third) failed entirely. This voided the machine's operation entirely. Because putting up with squealing is a completely different ballgame from not having a PC that works, I contacted Corsair to see which unit they could provide to replace the failed unit while I continued to wait. They kindly sent me (in one business day) a Corsair HXi Series, HX1200i, 1200 Watt (1200W), Fully Modular Power Supply, 80+ Platinum Certified. I received it today and installed it. It is almost identical to the AX1200i except that it is not all digital (and consequently requires a USB connection from the PSU to the motherboard to get the fairly useless Corsair Link software to work). Notably, while it makes some sound under load, it's not nearly as noisy as any of the three AX1200i units.And so I have a replacement unit while I continue to wait for Corsair to ship me an AX1200i replacement unit that operates the way a $310 PSU should.While I can commend Corsair's customer service, this particular unit is simply not recommendable. The HX1200i may be a better unit for those looking for less noise (although I cannot comment on reliability).I can say that in 2010, I built a different machine with a Corsair Professional Series HX1000 80 Plus Certified Modular Power Supply (CMPSU-1000HX). That PSU was virtually noiseless and presented no issues that I recall for nearly 6 years. All told, I believe Corsair makes good products (in all my PCs, I have Corsair memory with 2 X Corsair Vengeance LPX 16GB (4 x 4GB) DDR4 DRAM 3000MHz (PC4-24000) C15 memory kit for DDR4 Systems (CMK16GX4M4B3000C15R) in this build, and I currently use a Corsair Gaming K70 LUX RGB Mechanical Keyboard, Backlit RGB LED, Cherry MX RGB Blue and Corsair Gaming MM800 POLARIS RGB LED Lighting Hard Mouse Pad), but this is not among them.Needless to say, I recommend buying a different model if you are interested in the Corsair brand. 1The Best PSU for PC Money Can Buy! This PSU is undoubtably the best PSU for your PC. Efficiency level of at least 94% even at 100% load. Far as PSU goes, the only other Titanium grade option is mainly for servers, not for PCs. So this PSU from Corsair will be the BEST you can possibly get for your money. You get an abundance of connectors and thank God for the backward capabilities of the connectors. Unlike EVGA Classified PSU, which comes in Generation 1 and 2 where connectors for either generation is not compatible with the other generation, you can use the braided connectors sold by Corsair if you happen to have a set from your AX1200i. So if you're looking to upgrade from AX1200i to AX1500i, you can migrate all the connectors without problems. However, the connectors for all other Corsair PSUs are not compatible. It's also important to note that the connectors are long which indicates this PSU can easily support the current models of supertower PC cases. To give you an idea, I have had no problem using connectors on my CaseLabs STH10 with pedestals, which the PC case is over 4 feet tall. The lengthiest connector had to be the CPU connector and the distance from the PSU to the connector on the motherboard is approximately 3 feet, but the provided connector was long enough to cover the distance.Compared to AX1200i, this PSU is about 10cm longer, so after installing all connectors you may face some cramped space in your PC case where PSU is located. Based on my experience, Corsair 900D case may run into this cramped space issue when you decide to install both 480mm AND 240mm radiators in the bottom chamber. In fact, you probably won't be able to fit 240mm radiator and this PSU on the same side because I struggled a bit when installing 240mm radiator and this PSU on the STH10 (it was tight, but I was able to get both components squeezed in while minimizing pressures on the connectors). So if I struggled with STH10, then my experience tells me that such an installation is not possible on Corsair 900D because the bottom chamber is smaller for this case when compared to that of STH10. But then again, this shouldn't be too much of a problem for people since the space issue can easily be resolved with smart build design modification. That being said, if you are building a PC anything less than a full ATX, no sli nor crossfire setup, maxed out RAM, extreme CPUs etc., you should probably go with other PSU models because this is clearly an overkill for anything less. My current build includes two R9 295X2. YES, TWO! And those who are aware, that VGA is power hungry. Yet, with this PSU there's still enough headroom. When my PC is on, the fan on the PSU does not even turn on. But the fan does kick in during heavy load, especially when gaming on 4k resolution and both VGAs are being fully utilized. Still, no shortage of power here.My only problem is not directed at this PSU, but the option it provides. Specifically, the Corsair Link. Corsair really need to fix that God awful device or completely scrap the concept in its entirety. The software for Corsair Link is still unbearable to use and trying to get it to work properly is like pulling teeth. But to cover all basis, this PSU does allow the option to tap the Corsair Link functionality for monitoring power usage purposes. But I doubt most will connect this PSU to the Link especially since an alternative option is available - you can monitor either via Corsair Link or via internal USB which connects directly to your motherboard. I think most users will opt for the latter and the necessary USB connector is included. Strangely, Corsair did not include a Link adapter with this PSU, unlike AX1200i which does include the Link adapter and the connector. 5Quick fail 3 times, poor experience Update 11/22: PSU RMA is back logged almost 50 days. They offered me a lower model to replace my high end model. Seriously corsair, what are you doing?Minus 1 star for failing after a little over 2 months. Minus 1 for not responding to support email at all, waited 7 days. Minus 1 for making me call tech support and getting an ear full from them about how customer support is who I need to call even though when I called for the last 6 days, all circuits are busy. Minus a 4th star because your support website isn't actually mobile friendly, there were fields I needed to fill out to create an account and open a ticket that you can't see unless you are in desktop mode. Corsair I've loved your products for a long time but this has been a really bad experience.Update: PSU has failed again. Sudden random shutdowns even when system has been sitting at idle or just browsing news on the web. I'll be asking for a replacement for the 3rd time. Do not buy this PSU or any from this model line. Would give zero stars if I could. 1Scary Quiet! If you've built as many computer systems as I have, the last thing that you want to hear is for the power supply to come on for a few seconds, then turn off, as you know your system has just crashed. Well, if you use this one, get used to it! It turns on for a few seconds while the system is in the early boot stage, then "shuts down." (Actually the fan goes off.) I'm typing this in a very quiet environment where I can barely hear the fans on my case and gpu. I have a reasonably powerful system, not overclocked yet, but it doesn't even begin to tax this unit. I'm not qualified to judge the electrical characteristics of this psu, so if you want to see a review, go to AnandTech. I can tell you, though, that it's very quiet now, because it's barely working and so the fan is off. Of course, the Titanium rating tells me that it is very efficient.I used to use, exclusively, psu's from PCP&C, high-end units, but I've had some issues with them, so I decided to try this one. I liked it so well that I ordered another for my wife's computer, which currently has a high-end PCP&C psu which is annoyingly noisy. Hopefully, with these two I'll never have to buy another psu. (I'm getting long in the tooth.)I can't tell you if it gets noisy if taxed. When the system turns on, the fan makes a little noise but is not annoyingly loud.It has a bunch of cables. Some of them have to have the connector split apart. At first I thought it didn't have enough cables, then I realized that they came apart. For example, an eight pin cpu connector splits into two four pin connectors. The modular cables are nice to have these days, and I wouldn't buy a high-power unit without them.I haven't tried the software that comes with it, and if that's important to you, you need to do a search on it because I'm not sure that it works real well. 5Junk Nothing but issues.I have always loved Corsair, and been a die-hard fan, but this PSU has tested me.After having it for a few months, it started to power off and on randomly. It took me hours of troubleshooting to figure out it was my top-of-the-line PSU.Corsair support is a nightmare. Dealing with them is frustrating and terrible, and it took me a long time to get this item exchanged.A few weeks later, same issue with the new one. It's a piece of trash.Again, took me forever to try to deal with Corsair support to get a new one.Luckily, they sent me a "lower-end" model this time, since unsurprisingly, this one is discontinued. Hopefully I have better luck with this new model.Corsair, your support could use a lot of work. The RMA process should be easy, especially if you're going to sell poorly-tested high-end products plagued with issues. 1Don't Gamble Quit after 3 years. Worked fine until now, but there are multiple factors that make this unacceptable:1) Once it's proven unreliable, all enjoyment goes out of gaming when you don't know if it'll quit in the middle of your next game2) It should work for a lot longer for this price, especially considering it's been well taken care of I have an air filter on my PC case, the whole system load is maybe 60% or 70% of the PSU rating so it's not running hot, the other components are high quality ($2,500+ gaming rig), etc.3) Plenty of reports online of this exact issue (power cycling, the self-test light goes red, etc.), for the exact same model, and related models4) Your gaming PC is your baby... it's irritating in the extreme to have to contend with such flaky reason to have your experience deniedI'm disappointed, and when you enter your mid-30's and start having the income to cater to your hobbies, you become a lot less tolerant of mediocrity... sometimes not even second chances are given. 1Stay away! Very poor products and even worse "customer service". I was a huge fan of Corsair as I've owned countless products from cases, RAM, cooling, SSD's and PSU's. Never again.This is a premium priced PSU but the customer service is bargain bin. I paid a lot of money for a power supply that has been nothing but trouble since I got it not even 6 months ago. The web is littered with complaints on the AX series all with the exact same issues with many on their own forums. These PSU's should have been recalled, that much is clear. Now I'm now stuck with a lemon product and according to more complaints online there's not even a guarantee that a replacement will even resolve the issues. Just like a lot of other reviews my power supply constantly shuts off whenever if feels like it and gets stuck in a loop. Off and on, off and on. I've spent countless hours tearing down my PC and swapping parts (even spending more money on buying extra components to trouble shoot) only to have it happen again and again and again.I just got off the phone with a customer service representative which took 3 calls and then almost 45 minutes of waiting to finally speak with an outsourced labor representative who had zero product information. Corsair offices close before I get off of work so I had to spend several of my lunch breaks just trying to get a hold of someone to help. When I finally do they tell me that the AX860i isn't even in stock! Are these units defective? Why don't you keep a stock? Is Corsair issuing a recall? These are questions I would like answers to but she had no knowledge, only apologies and three unacceptable options.1. Call back next week and see if back they're in stock. Seeing as it took as long as it did to get through to someone that's not something I'm willing to do again. I need a replacement ASAP so "checking back in" is not an option.2. Have Corsair order a replacement from Taiwan and wait for it. This is the person who is supposed to help me get an express RMA mind you.3. Put up another $200 of my own money and order one online, wait for it to be delivered, return the defective power supply while paying return shipping out of pocket, then submit a ticket through Corsair and pray for a refund. I am most definitely not putting up any more of my own money only to have no leverage should Corsair decide not to pay out.If this is Corsair's idea of customer service they've lost a loyal customer. I've been buying their products since the early 2000's. In my current build I have a case, a PSU, RAM and two SSD's. No company is perfect but this is just unacceptable.I'm concerned with the high defect rate of the AX series and what Corsair is doing about them. Can they actually assure that the replacement PSU I'll receive will be problem free because looking on their forums all I see is their forum reps denying that there's an issue and instead blaming the customer. Corsair reps will tell you it's the motherboard as they won't take any responsibility or admit there's an issue with the AX series. They will also make you pay for return shipping of their faulty $200 product even though it's only a few months old. I've been pulling my hair out trying to fix this issue. I'm speaking with an attorney and looking to gather others together who've been affected. After looking at all of the reports of this same issue Corsair should have recalled this unit but instead they deny there's a problem. Go look on their own forum. It's filled with complaints of the EXACT same issue. This problem occurs in at least the AX760i, AX860i and AX1200i series PSU's. I imagine there's more. They will never get another dime from me. 1Warranty service is garbage I'm never buying another Corsair product again. And I have been buying their products exclusively for years. In short, they don't honor their warranties. Even if they did honor the warranty, their terms now say they offer two options: You can either send them the defective part first (and down your system for a week or more) or give them a credit card so they can charge you in case you don't return the broken/defective part or if they don't think it was covered under warranty. Now, take a company like APC who makes UPSes (big heavy backup batteries). They have no problem sending out a 35 pound replacement as long as you provide proof of purchase, no questions asked, no credit card required. Just explain the problem, give them a shipping address and return the old one in the box the new one came in. That is industry standard for virtually all hardware vendors. But not Corsair. Corsair has a tech support department run by children who cannot answer emails and who do not adhere to their own warranty. So if you buy from them, just pray nothing happens to your product because they're not going to do anything for restitution. Do yourself a favor and find a different manufacturer. 1

In fact, you probably won't be able to fit 240mm radiator and this PSU on the same side because I struggled a bit when installing 240mm radiator and this PSU on the STH10 (it was tight, but I was able to get both components squeezed in while minimizing pressures on the connectors). So if I struggled with STH10, then my experience tells me that such an installation is not possible on Corsair 900D because the bottom chamber is smaller for this case when compared to that of STH10. But then again, this shouldn't be too much of a problem for people since the space issue can easily be resolved with smart build design modification. That being said, if you are building a PC anything less than a full ATX, no sli nor crossfire setup, maxed out RAM, extreme CPUs etc., you should probably go with other PSU models because this is clearly an overkill for anything less. My current build includes two R9 295X2. YES, TWO! And those who are aware, that VGA is power hungry. Yet, with this PSU there's still enough headroom. When my PC is on, the fan on the PSU does not even turn on. But the fan does kick in during heavy load, especially when gaming on 4k resolution and both VGAs are being fully utilized. Still, no shortage of power here.My only problem is not directed at this PSU, but the option it provides. Specifically, the Corsair Link. Corsair really need to fix that God awful device or completely scrap the concept in its entirety. The software for Corsair Link is still unbearable to use and trying to get it to work properly is like pulling teeth. But to cover all basis, this PSU does allow the option to tap the Corsair Link functionality for monitoring power usage purposes. But I doubt most will connect this PSU to the Link especially since an alternative option is available - you can monitor either via Corsair Link or via internal USB which connects directly to your motherboard. I think most users will opt for the latter and the necessary USB connector is included. Strangely, Corsair did not include a Link adapter with this PSU, unlike AX1200i which does include the Link adapter and the connector. 5Quick fail 3 times, poor experience Update 11/22: PSU RMA is back logged almost 50 days. They offered me a lower model to replace my high end model. Seriously corsair, what are you doing?Minus 1 star for failing after a little over 2 months. Minus 1 for not responding to support email at all, waited 7 days. Minus 1 for making me call tech support and getting an ear full from them about how customer support is who I need to call even though when I called for the last 6 days, all circuits are busy. Minus a 4th star because your support website isn't actually mobile friendly, there were fields I needed to fill out to create an account and open a ticket that you can't see unless you are in desktop mode. Corsair I've loved your products for a long time but this has been a really bad experience.Update: PSU has failed again. Sudden random shutdowns even when system has been sitting at idle or just browsing news on the web. I'll be asking for a replacement for the 3rd time. Do not buy this PSU or any from this model line. Would give zero stars if I could. 1Scary Quiet! If you've built as many computer systems as I have, the last thing that you want to hear is for the power supply to come on for a few seconds, then turn off, as you know your system has just crashed. Well, if you use this one, get used to it! It turns on for a few seconds while the system is in the early boot stage, then "shuts down." (Actually the fan goes off.) I'm typing this in a very quiet environment where I can barely hear the fans on my case and gpu. I have a reasonably powerful system, not overclocked yet, but it doesn't even begin to tax this unit. I'm not qualified to judge the electrical characteristics of this psu, so if you want to see a review, go to AnandTech. I can tell you, though, that it's very quiet now, because it's barely working and so the fan is off. Of course, the Titanium rating tells me that it is very efficient.I used to use, exclusively, psu's from PCP&C, high-end units, but I've had some issues with them, so I decided to try this one. I liked it so well that I ordered another for my wife's computer, which currently has a high-end PCP&C psu which is annoyingly noisy. Hopefully, with these two I'll never have to buy another psu. (I'm getting long in the tooth.)I can't tell you if it gets noisy if taxed. When the system turns on, the fan makes a little noise but is not annoyingly loud.It has a bunch of cables. Some of them have to have the connector split apart. At first I thought it didn't have enough cables, then I realized that they came apart. For example, an eight pin cpu connector splits into two four pin connectors. The modular cables are nice to have these days, and I wouldn't buy a high-power unit without them.I haven't tried the software that comes with it, and if that's important to you, you need to do a search on it because I'm not sure that it works real well. 5Junk Nothing but issues.I have always loved Corsair, and been a die-hard fan, but this PSU has tested me.After having it for a few months, it started to power off and on randomly. It took me hours of troubleshooting to figure out it was my top-of-the-line PSU.Corsair support is a nightmare. Dealing with them is frustrating and terrible, and it took me a long time to get this item exchanged.A few weeks later, same issue with the new one. It's a piece of trash.Again, took me forever to try to deal with Corsair support to get a new one.Luckily, they sent me a "lower-end" model this time, since unsurprisingly, this one is discontinued. Hopefully I have better luck with this new model.Corsair, your support could use a lot of work. The RMA process should be easy, especially if you're going to sell poorly-tested high-end products plagued with issues. 1Don't Gamble Quit after 3 years. Worked fine until now, but there are multiple factors that make this unacceptable:1) Once it's proven unreliable, all enjoyment goes out of gaming when you don't know if it'll quit in the middle of your next game2) It should work for a lot longer for this price, especially considering it's been well taken care of I have an air filter on my PC case, the whole system load is maybe 60% or 70% of the PSU rating so it's not running hot, the other components are high quality ($2,500+ gaming rig), etc.3) Plenty of reports online of this exact issue (power cycling, the self-test light goes red, etc.), for the exact same model, and related models4) Your gaming PC is your baby... it's irritating in the extreme to have to contend with such flaky reason to have your experience deniedI'm disappointed, and when you enter your mid-30's and start having the income to cater to your hobbies, you become a lot less tolerant of mediocrity... sometimes not even second chances are given. 1Stay away! Very poor products and even worse "customer service". I was a huge fan of Corsair as I've owned countless products from cases, RAM, cooling, SSD's and PSU's. Never again.This is a premium priced PSU but the customer service is bargain bin. I paid a lot of money for a power supply that has been nothing but trouble since I got it not even 6 months ago. The web is littered with complaints on the AX series all with the exact same issues with many on their own forums. These PSU's should have been recalled, that much is clear. Now I'm now stuck with a lemon product and according to more complaints online there's not even a guarantee that a replacement will even resolve the issues. Just like a lot of other reviews my power supply constantly shuts off whenever if feels like it and gets stuck in a loop. Off and on, off and on. I've spent countless hours tearing down my PC and swapping parts (even spending more money on buying extra components to trouble shoot) only to have it happen again and again and again.I just got off the phone with a customer service representative which took 3 calls and then almost 45 minutes of waiting to finally speak with an outsourced labor representative who had zero product information. Corsair offices close before I get off of work so I had to spend several of my lunch breaks just trying to get a hold of someone to help. When I finally do they tell me that the AX860i isn't even in stock! Are these units defective? Why don't you keep a stock? Is Corsair issuing a recall? These are questions I would like answers to but she had no knowledge, only apologies and three unacceptable options.1. Call back next week and see if back they're in stock. Seeing as it took as long as it did to get through to someone that's not something I'm willing to do again. I need a replacement ASAP so "checking back in" is not an option.2. Have Corsair order a replacement from Taiwan and wait for it. This is the person who is supposed to help me get an express RMA mind you.3. Put up another $200 of my own money and order one online, wait for it to be delivered, return the defective power supply while paying return shipping out of pocket, then submit a ticket through Corsair and pray for a refund. I am most definitely not putting up any more of my own money only to have no leverage should Corsair decide not to pay out.If this is Corsair's idea of customer service they've lost a loyal customer. I've been buying their products since the early 2000's. In my current build I have a case, a PSU, RAM and two SSD's. No company is perfect but this is just unacceptable.I'm concerned with the high defect rate of the AX series and what Corsair is doing about them. Can they actually assure that the replacement PSU I'll receive will be problem free because looking on their forums all I see is their forum reps denying that there's an issue and instead blaming the customer. Corsair reps will tell you it's the motherboard as they won't take any responsibility or admit there's an issue with the AX series. They will also make you pay for return shipping of their faulty $200 product even though it's only a few months old. I've been pulling my hair out trying to fix this issue. I'm speaking with an attorney and looking to gather others together who've been affected. After looking at all of the reports of this same issue Corsair should have recalled this unit but instead they deny there's a problem. Go look on their own forum. It's filled with complaints of the EXACT same issue. This problem occurs in at least the AX760i, AX860i and AX1200i series PSU's. I imagine there's more. They will never get another dime from me. 1Warranty service is garbage I'm never buying another Corsair product again. And I have been buying their products exclusively for years. In short, they don't honor their warranties. Even if they did honor the warranty, their terms now say they offer two options: You can either send them the defective part first (and down your system for a week or more) or give them a credit card so they can charge you in case you don't return the broken/defective part or if they don't think it was covered under warranty. Now, take a company like APC who makes UPSes (big heavy backup batteries). They have no problem sending out a 35 pound replacement as long as you provide proof of purchase, no questions asked, no credit card required. Just explain the problem, give them a shipping address and return the old one in the box the new one came in. That is industry standard for virtually all hardware vendors. But not Corsair. Corsair has a tech support department run by children who cannot answer emails and who do not adhere to their own warranty. So if you buy from them, just pray nothing happens to your product because they're not going to do anything for restitution. Do yourself a favor and find a different manufacturer. 1
