    Works very well and does not make any sound. Modular ability allows for you to choose what cables you should use and what cables you don't need to use.

    Got an 5900xt, Rtx 3080 extreme, 64 gb ram, this power supply fits the build. Only con it only has 3 8 pin PCI-E connectors, and my 3080 uses three connectors already and I'm certain future video cards will need 4 connectors and there's a socket for a forth. It comes with a ton of other connectors. It's whisper quiet.

    I think I have a medium size case and it barely fit... It is about the same height as my old 700 wat power supply but a lot longer.

    Im fairly new to building pc's, but replacing my old 650W to this 1000W has not only taught me a lot about how a pc runs, but how much of a difference this product alone has had on my build. I love this a lot

    It works. It’s quiet. I chose this one as the connectors are the same as the existing one on the power supply end so that no re-harnessing of the chassis was required except for one new cable to a graphics card. It’s enough to support 3080ti box with ryzen 12 thread.

    Grabbed this after my 750 but the dust. Has ran flawlessly and handled some pretty good overclocking with a 5800x and a 6800xt and doesn’t break a sweat. Cables could be a little more flexible at the ends. Comes with plenty of extra cables. Wouldn’t use any other psu besides a Corsair!

    Fantastic, No Coil whine going to any of my systems (Ive bought 3 of them) no weird shutoff issues, no fan noise, it honestly just works. Was not a fan of corsair for a while, but this is pretty solid.

    A good PSU so far for the price. My only complaint is the modular PCI cables are not snug enough when plugging into the PSU. So be sure to really seat the cables into the unit until they catch on the clip, and make sure they will not pull out. Other than that, it is quiet and I've had no problems whatsoever with the unit running 24/7. The cable quality seems to be good also. It has six 8-pin PCIe connections on the unit for plenty of expansion.

    I bought this to be able to power a Ryzen 9 5900X, it works. It also has enough modules for the RTX 30 series graphics cards, if you want 3 PCI-e cables plugged into a 3070 or 3080 Ti, it will work and have as much power draw as it needs to operate. This is a good PSU.

    It works, it loses everything, no issues. Not much else to say. Easy to install and came with all the cables. I will admit custom cables might be in the future just because the ones that come with it are not the easiest to manage due to flexibility, but I do like how they’re braided and am happy for now.

    Modularity is nice. Gets extra cables out of the way. Solid power supply if you buy the proper size and not bad on the power bill or wallet.

    Nice 1000w psu with modular cables but?

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    It works. My issue is why make modular cables that daisy chain or split when all the cables supplied should be singles to each system component? With even a shroud over the psu and bottom its still kind of hard to hide the extra cable dongle like on the video card cable. The psu isn't haven't any issues other wise. No noticeable fan noise or buzz. I just wish the cables made more sense.
