Corsair AXi Series, AX760i, 760 Watt (760W), Fully Modular Digital Power Supply, 80+ Platinum Certified

I've used several different power supplies in a handful of PC builds over the years and this one far exceeds all the others. I build dual-purpose home-office PCs that can serve as a work-PC during the day yet support demanding entertainment during off-hours and weekends. My PCs need to be quiet, yet powerful and I am afraid to go liquid (I like zero-maintenance). This Power supply has cut the noise and heat down substantially as a result of its innovations. By only utilizing the necessary power WITHOUT dissipating unused energy as heat my PC runs substantially cooler during less demanding daytime work. As a result, the fans operate at far lower RPMs, and sometimes not at all, which keeps the PC quiet and cool. Just after completing this build, when I would walk into my office I would often to look see if the PC was still running because I couldn't hear it. In addition to the AX760i's internal fan I have the Cooler Master Hyper 212 EVO - CPU cooler plus two 120 mm fans. The Cooler Master fan is the ONLY one that I can hear (I'll likely replace the fan with a better one). My system is running at a core temp of 35 degrees Celsius as I type. The AX760i has made a HUGE and welcome difference in my home office. I would absolutely buy this again.

Bought this unit knowing that it was way more than I needed, but Corsair quality and support were legendary so I splurged. The computer worked for a few hours and then began an endless reboot cycle. I thought that it COULDN'T be the PSU. After months I finally looked at the Amazon reviews and the Corsair support site and found that this is a known problem. OK, well that happens. I got an RMA, paid for return shipping and Corsair replaced it. What do you know, same problem. Well it CAN'T be the PSU so I spent months checking everything. Motherboard sent back for repair/test (they found nothing wrong), replaced memory ... everything swapped. I finally gave up and brought it to a repair shop. They put in a $50 PSU and it worked ... so I got 2 bad PSU's from Corsair.No problem ... Corsair offered to replace it again, if I pay for shipping again. No confidence now so I ask for a refund. No problem they say ... just ship it back (pay for shipping) and they'll refund minus tax. No way will they pay for either ship, the tax, my lost time, the repair shop ... nothing. Finally disgusted I say ok. That was 2 months ago. Still waiting for the refund.Corsair: never again.

It worked fine for a couple months but started acting up around the time I installed the Corsair Link. Even when uninstalled, the computer would be unable to recover from standby or hibernation, only boot cycling. Recently, the comptuer started randomly shutting down (anywhere from 5 minutes to a week after boot), then getting stuck in boot cycling until the cables were switched to different ports on the PSU.Upon replacing the PSU with a seasonic 760W platinum to make my RMA case with Corsair, I have been stable for over 24 hours so far.Also, I noticed that the 3.3, 5, and 12V values do not fluctuate at all, even under 100% system load (all components) with the new Seasonic PSU, whereas the Corsair ones moved from below to above those values constantly. (measured with AIDA64)Given the amount of similar experiences from others, I may not bother to RMA this unit.

the fan doesn't respond to commands to speed up or slow down and makes an insane racket. i had planned on this for my dask tower, but after 2 days of the mind blowing noise i moved it to a server and walked away.it's a great product, wonderful, steady power, but the fan issue is enough to kill it.

First of all, I bought this AX760i, which is manufactured by Flextronics, specifically because it's not manufactured by Seasonic (the non-i versions are Seasonic). You might wonder why, because Seasonic supplies are top notch. Well, they are, except that they ALL (yes, every single line, from the more basic units to the 80Plus Gold and Platinum units) prone to a high pitched whine sound depending on what hardware you use with them. I've personally experienced this and my high frequency hearing is VERY good and the whine in the Seasonic PSU I had was audible to me from a room or two away. I'm the type of person who can tell you immediately upon walking into a house if there is a CRT TV on ANYWHERE in the house. If that doesn't describe you, I might refer you to the Seasonic-manufactured AX760 instead which has slightly higher efficiency (though both do meet 80plus Platinum) and quality-wise is more proven than Flextronics (not saying Flextronics is bad - wouldn't have bought this supply otherwise - but they aren't as proven as Seasonic).Anyway, onto the packaging. It came in a really high quality box and included cloth bags and stuff. Really nice packaging. I'd be willing to give it all up to save even $1 off of the price, but such is life. I realize other people would still see that price as being high (compared to lesser supplies) and would then go on to whine that it cost that much and didn't include all this useless extra stuff. Make sure to smack every person you hear do this, because it's people like those that force us to pay extra for cloth bags for our power supplies. The cloth bag does literally nothing, and heck, I'd rather they get rid of it even if it saved only a penny from the cost.This is a modular supply. The cables that this comes with are numerous and provide plenty of connectors for SATA especially. This is a modular supply so you can keep your extra cables out of the way, potentially improving airflow and ease of working on the machine later. However, I recommend you keep all the spare cables in the case, maybe ziptied in a corner. I don't know about you, but if I didn't do that, I am likely to lose them. And honestly I'm not interested in moving more stuff that should be in my case to yet another box in the closet. If you keep the box to the PSU that's fine, but not all of us have the space to do that.The cables included are pretty good but not free of issues. I'm using the supply in a Fractal Design Define R4 mid-tower case which has the PSU at the bottom of the case. The ATX cable is just barely long enough to reach the connector on the Asus Maximus VI Hero - those unfortunate enough to have bought a board with a stupidly rotated ATX power connector (one that isn't right along the edge of the board) may have trouble with the length of this cord. In that case I'd have needed to run the ATX power cable without using the cable management systems of the case.There are also issues with the SATA power cables. Again, there are plenty of them - 12, in fact. They are meant for a case like mine where the power supply is at the bottom, which for me is a good thing. The reason I say that is because the SATA power cables are keyed and only go one way. If you put this PSU with the stock cables at the top of a case, the keys in the connectors will force you to run the cables backwards if you use multiple drives per chain. Say you used all 4. You'll need to run the power down from the top of the case to the BOTTOM drive and then you can chain them UPWARDS, which would be a pain. However, for a case like my Define, this is exactly what I need. My previous PSU had the power connectors aligned for a top-down PSU arrangement, which had the same problem in my bottom-PSU case.There's another issue with the SATA power cables that will affect most of us putting more than one drive on a chain, and this is a problem with almost every PSU that has SATA cables. They are WAY TOO FAR APART. I'm not sure why PSU manufacturers seem to think that SATA drives are installed with like 4 inches between them. With these cables/connectors, if you try to use them on drives that are next to each other (you know - how drives are ACTUALLY INSTALLED) - you absolutely MUST stagger them or you WILL be snapping connectors on your drives (and plus it would look funky with several inches of useless cable sticking out between each drive). In my case this isn't THAT big a deal because it offers 8 HDD spaces and I use them all. I run 2 SATA cables for the entire group, one handling drives 1,3,5,7 and the other handling 2,4,6,8. They absolutely MUST be installed like this to keep the slack between the cables from breaking things and looking awful while doing so.Oh, and I thought of one more issue with the SATA connectors. 4 per chain, yet no capacitors? I'm using them this way because I have to and it is working, but I can't say I feel that comfortable about it. It would make the cables much uglier, but if you don't want to use capacitors, I feel you should have given us 4 chains with 3 connectors rather than 3 chains with 4 connectors.Anyway, SATA power cable problems aside, I recommend this power supply if you have good high frequency hearing, and the non-i Seasonic version if you have poor high-frequency hearing or otherwise aren't bothered by constant high pitched whine noises.

High quality you have no ideas !!

Perfect for my pc system.
