05-06-2025Works perfect. Great price and better warranty than my 1200X that went out all the sudden. I could have had a new one if I had kept my receipt for warranty. So, that was my fault. This time, I have my Amazon receipt right here. Corsair did try to help me locate the receipt for the old one. But this one is working so perfect. I think I like it better.

> 3 dayI bought this PS to replace my Corsair 750. I machine was shutting it self off and rebooting randomly and I believe that it was starving for juice. So I followed the advise of a PC guy and got the Corsair 1000 and put in about 5 fans and the problem went away.

> 3 daySo quiet because the fan doesnt even run most of the time. Even when it does, it adds little to no additional noise. However, beware because the cables are pretty stiff. SATA power connectors were right angle connectors so it gave me some difficulty with positioning RGB hubs. The 24 pin cable pins looked bent slightly and made quite difficult plugging it into the motherboard. I will not enjoy trying to unplug it.
