Reliable 400 W ATX power for everyday builds

This KHACHIMO unit delivers 400 W of continuous power through a standard ATX form factor. It is suited for office PCs, home multimedia systems and entry-level gaming rigs that do not demand high-wattage headroom. Each unit is tested before shipping to confirm basic operation.

Fixed-cable layout suits straightforward assembly

The non-modular design means all leads are permanently attached, which keeps cost down but requires a case with enough room to route unused cables. Builders planning multi-GPU setups or extensive drive arrays will need a higher-capacity supply with modular cabling.
