KHACHIMO 400W ATX Power Supply P2H-5400V

400 W ATX Gold Power Supply

This KHACHIMO 400W ATX unit delivers 80 PLUS Gold efficiency for lower power draw and cooler operation. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. It suits builders assembling a reliable mid-range desktop.

Who it suits and who it does not

Ideal for office PCs, home workstations and budget gaming rigs that value quiet operation and efficiency. The Zero RPM fan mode stops the fan at low and medium loads for near-silent running. Builders needing more than 400 W for high-end graphics cards or multi-GPU arrays should look at higher-capacity units. Systems requiring server-grade redundancy or specialised form factors will need different designs.

Single deciding specification

The 400 W rated output is the key figure that determines whether this unit can power your chosen components. Verify the total system draw under load against this limit before purchasing. The 80 PLUS Gold certification confirms high efficiency across typical workloads. Modern Standby support is required for the fastest sleep-wake behaviour on compatible motherboards.
