500W ATX power supply for standard builds

The KHACHIMO PWS-504P-1R delivers 500 watts through an ATX form factor suited to mainstream desktop configurations. It is intended for system builders who need a straightforward replacement or a new unit for a typical office or home computer.

Installation follows normal ATX mounting and cabling

The unit fits standard ATX chassis cut-outs and uses the usual screw pattern, so fitting it requires only basic tools. Because the supplier only confirms that the unit tests working, builders should verify connector counts and cable lengths against their motherboard and GPU before closing the case.

ATX specification limits total output

The ATX standard caps combined rail power at the rated 500 watts and defines a fixed set of motherboard, peripheral and PCIe connectors. Systems demanding higher peak loads or additional PCIe cables will exceed what this design can provide.
