  • Product typeATX

Ready for standard ATX builds

This 400W ATX power supply is intended for basic desktop systems that do not require high-wattage components. Office workstations, home PCs and budget upgrades are the typical use cases.

Steady 400W output under load

The unit is rated to deliver its full 400W continuously rather than only in short peaks. This behaviour helps keep voltages stable during extended work sessions or moderate gaming loads.

Straightforward ATX installation

Standard ATX dimensions and connector layout allow the supply to fit most chassis without modification. The only common issue is cable length in full-tower cases where routing distance can exceed the supplied leads.
