400 W ATX power supply for basic builds

This 400 W ATX unit is intended for entry-level desktop configurations that need a simple, tested power source. It suits office PCs, home-workstations or light multimedia machines where peak demand stays well within the rated output.

Sustained-load behaviour on the 300 W rail

The Edge R300 label indicates a continuous 300 W capability, so the supply maintains stable voltage when the system draws steady power over long sessions. Short bursts can reach the 400 W peak, but prolonged heavy loads should remain near the lower figure to avoid thermal stress.
