What this 400 W ATX unit powers

The KHACHIMO EFRP-400INF is a new 400 W ATX switching power supply built for standard desktop builds. It delivers the rated output for office workstations, home PCs and light gaming rigs that do not demand extreme headroom. The unit has been test-working at the factory and is described by the maker as good quality.

What to verify before ordering

Confirm that your case accepts a standard ATX form-factor supply and that the motherboard uses a 24-pin main connector plus the usual 4-pin or 8-pin CPU plug. Check the graphics card, if any, for its own power connectors and total board draw so the 400 W budget is not exceeded. Ensure the chassis has the mounting holes and rear cutout that match the ATX specification.

Behaviour under sustained load

Under continuous load the supply maintains its rated output within normal ATX tolerances while the internal fan adjusts speed to manage thermals. Voltage rails stay stable during extended work sessions or long gaming periods rather than only during brief peaks. The design targets reliable operation for typical daily workloads without thermal throttling.
