> 3 dayYeah, I got this Power Supply for my PC. I spent over 4-5 hours installing it and organizing the cable management in the back. After all that time, I was proud of my work. I put everything back together turned on my PC and......NOTHING. My PC wasnt powering on unfortunately. I was so confused. I re-opened the back panel to check the cables and everything, I was sure I connected everything the way it was suppose to be. I double checked if everything was plugged in correctly. Tried turning on PC again and still Nothing. I was so pissed off. I tried changing the cables multiple times and no luck. after another 2-3 hours trying to figure out why the PSU isnt powering my PC. I came to an agreement that my PSU by COSAIR was faulty and arrived broken. $160 wasted. I used a 1000w EVGA PSU and it worked like a charm.

> 3 dayI am very pleased with my purchase and have to say this is a GREAT Power Supply. Robust and easily ran my RTX 2080 ti and Elgato 4k pro setup after off-brand 735w failed multiple times.

> 3 dayThis thing comes with everything you need to build a PC. All cables are very well built and sturdy, and I didnt have any issues with length. The PSU is super quiet, and even runs without a fan under light load. Installed quickly and easily in the Lian Li Lancool II mesh.
