    Works great, has saved my PC from dying a horrible death, It's been handling all the games I play perfectly well with no weird electricity noises like my last power supply was doing. Note to self and everyone else, double check the power supply you're getting on a budget pre-built PC so you don't have to go and buy a new power supply so early like I did.

    1000W PSU purchased for long-term upgrades. Used with 3070ti at first, now 3080 FTW3 12gb, and I know I’ll be able to use it with 40 series down the road. Pretty quiet, sometimes I’ll sit at my desk and try to log in before realizing CPU is sleeping since the noise is so minimal when it is on. Corsair is a very reliable brand as long as you know what you’re doing (don’t use 3rd party cables, stay grounded, etc). It fit in a Corsair case as expected.

    Put this in my PC after my old power supply dealt with one too many Texas power outages. Has been a real trooper. Runs my rig quietly and without getting hot.

    Installed it within 30min, only hiccup was my case that it was a little bit tight for but I got it in and havent had any problems since. It’s been doing the job so far and a good one at that. This is my first modula PSU and I would recommend it 10/10 to anyone who needs a replacement.

    Not a bad power supply it's pretty quite came with all the cords needed with extra and with 1k watts you'll never really run out handles most newer parts and what also nice is that you don't just have a lot of cords coming from the power supply forcefully like other companies it has none forcing you to use so you don't have extra laying around

    No complaints. Corsair make good products. Price was a little high but spending a little more to make sure your house doesn't burn down is a wise investment. When building a PC get a good power supply and good GPU. You can cut corners on the other parts. Don't cut corners on your power supply
