Worked great for 10 months then fried my PC.
||Posted . Owned for 9 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I bought this in late March and it ran great until last night when I went to turn my pc on. It randomly sparked and fried my entire PC. CPU, MOBO, RAM, and GPU. I’ve spent a year buying and upgrading parts for this PC and I’m absolutely gutted. I love Corsair products and have always used them, but something is wrong with this one. Hope this never happens to anyone else.

Didn't come with enough plugs for my gpu
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.It's fine and their 1000 version is nice, but it didn't come with enough GPU cables for my 3080 (needed 3 6+2s)
I would recommend this to a friendOnly Lasted 3 Months
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This PSU was fine for 3 months then it couldn't produce enough power to run my RTX 3060. I swapped to different cables and changed output ports but it just couldn't output enough power and shut down during gaming. Switched to my 600w backup PSU and everything works fine. No crashing and my GPU gets enough power. Way too expensive to only last a few months.

Only two PCIe 6+2 cables.
||Posted . Owned for less than 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Specifically went up from 750 to 850w unit to get one more 6+2. I see the photo ahows one more 8 pin on the PSU so i thought i’d be good. BUT NO?? Somehow this unit comes with a third 8 pin CPU connector, completely ruining the 3 dedicated canles for a 4080… come on corsair.
