Customer Reviews

Perfect for my server


I bought this to replace a cheap (noisy) PSU I'd bought for my new home server build. I have no idea how loud the fan is because it has yet to even come on. Only problem is I can now hear my hard drives. Plenty of connectors, very small, perfect for low power builds.
