KHACHIMO PRM400 400W ATX power supply

This KHACHIMO PRM400 unit delivers 400W of power through the ATX form factor. It is intended for desktop builders assembling or repairing standard tower systems that require a basic switching supply. The unit arrives new and has been tested for operation.

ATX form factor limits case compatibility

The ATX physical standard restricts this supply to cases designed for that specific layout. Builders working with small form factor, proprietary or server chassis will find it does not fit. The 400W rating also caps the total system draw, so configurations with high-end graphics cards or many drives are not supported.
