    Nice power supply that packs a punch of 1000W. Comes with tons of cables so you'll be able to plug in all of your peripherals. No issues at all, works great. Not a bad price either.

    Loving this PSU, quiet and powerful, fan rarely turns on this provides enough power for a 1080, 3060 and 3080 at full load! only complaint is I wish they would have included a couple more PCIe cables.

    I looked for months to find a 1000 watt psu, and thanks to Best Buy i finally found a great deal on a well known brand for a good price. $189.99 is a awesome deal when most are at a minium $250-$300. Gold rated at that. I can now overclock my RTX 3090 and 5900x as much as i want with no worries.

    Bought this because my old power supply was on the edge of murdering my entire build which I didn't want to risk for any longer. My first impression was how insanely quiet it is, my computer is almost dead silent now with this. Turns out my old PSU was what was making all the noise, as I have Noctua fans installed in my pc. I would strongly recommend this to anyone who is in the market for a new psu or building a new rig.

    Corsair quality as you would expect. The cables are some of the best out. Needed to upgrade from 850 watt to this 1000 watt as my overclocked 11900K and 3090 needed more power.

    I have been using this power supply for a few months now and it runs great it handles a 13900k and a 3080 v2 no issue. I have been using corsair power supplies since I first started building PCs and so far have not had any issues with their quality. Works well, and they have been reliable for me for years. If you require a 1000w this is one you should consider among the plenty of other great power supply manufacturers.
