I needed an affordable power supply for a retro PC. The cheapest I bought elsewhere had 5V line problems (dropping to 4.5V under load), so I returned it and bought this one on CoolBlue. I am very happy. 5V line is rock stable and I don't need to use a 24-20pin ATX adapter cable, this one allows you to disconnect the 4 additional pins. I wish it would have another floppy disk plug, but that is expected. Very quiet also. Nothing to complain about.

Bought to replace a power supply from a 2012 PC whose power supply fan was no longer working properly. Easy to install and cables not too stiff. Compared to the old power supply, this one is quieter. Bought from CB because of the simplicity of ordering and service history.
