08-06-2025Was building my new pc, I hooked up the psu and got ready to test it out to make sure all was working. Nothing. I was worried it was the mobo at first, but I put a different psu into my pc and worked like a charm. It sucks because I had limited time to build my pc, as I rarely have days off from work. I had to run to the nearest Best Buy that night to buy ANOTHER psu. Luckily that one worked. This was a waste of money. Never buying a Corsair psu again.

Greater than one weekSoon as I plugged it in and tried to boot, POP. Smoke out of the main 24PIN ATX cable. Shouldve looked at the recent reviews, ah well. 2 HDs arent registering as of writing this, but everything else is fine otherwise. Never again. Hopefully the next few buyers will have better luck than I.

> 3 dayUpgraded from a 550 off brand that came with my original build. Biggest upside was that my original was. Not fully modular and this was. Like why do they even make power supplies not fully modular? This was a huge step up for me.

> 3 dayThe unit will shut down the main power to the motherboard randomly. May be the main 12v cable connection.

> 3 dayI cant hear it at all, I imagine it can be decently quiet at full load too.
