    Great Power supply, looks good in my case. Using it for a system with a 7600x and 7800xt and more than enough power to spare. Includes white cables, so make sure that fits the aesthetic of your build. Stays cool and quiet and even shuts off fans when not using a full load.

    I used this on an older AMD FX8350 and RTX 2080 TI. Great performer. I feared the 990 series mother board was in jeopardy, fortunately this PS saved the day. Truly modular. Great price too.

    I bought this power supply when I was building my $1800 gaming computer, well over two or three years ago, and it has held up wonderfully!

    One of the best power supply units I purchased in the last few years. Completely modular and provides the power you need to run advanced peripherals. Add to that the appropriate color for an all-white setup. Nicely done,

    I narrowed my PC issues down to GPU or PSU. Was able to confirm it was the PSU. I had the old one for 10 years (also Corsair). I decided on white because I already planned a full upgrade including case this year (kept case and PSU with all former upgrades). It's an added benefit that I got it on sale! Now I no longer have the problems from before. My old PSU had a good run. I hope to keep this one just as long.
