> 3 dayThe first one I ordered arrived in the Corsair box, everything looked like it was in great condition and it was really easy to install. I got it all hooked up and when I pressed the power button, the power supply made a popping sound and the entire room filled with a burnt plastic smell. Obviously the computer didn’t turn on lol.

> 3 dayThe product is fine, but do not purchase from this item from GREZ LLC, they will charge you more than double the average price and their returns service is the worst Ive ever experienced.

09-06-2025If something arrives Dead, it can easily be replaced through Amazon thanks to not only the return window, but also their 90-day warranty under tech support. So far, mine hasnt died yet, and it was so nice to be able to cut down on the amount of cables my old setup had. This PSU runs silently and its nice to have the room for upgrades in the future. My only concern is that the plug-in cable ( the cable where you plug the battery into the wall), doesnt stick all the way into the PSU socket. Still runs great though.

> 3 dayPerforms fantastically, cant hear it at all. Using it to run an i7 5820K OCd to 4.1GHz with 2x EVGA GTX 580s on an ASUS X99 Sabertooth and it gives me no issues whatsoever. And its Corsair so its got a practically never-ending warranty. Been running it for over a year and its not stumbled once. Highly recommended.

> 3 daycorsair makes junk, ordered this PSU and it lasted roughly 18 months, tried to file a warranty claim and got the run around. corsair is the first power-supply ive ever had fail in the 8+ years ive been building computers. def not worth the money, i would recommend another brand if youre building a high end gaming PC.
