400 W ATX Gold Power Supply

The KHACHIMO P2H-5400V is a 400 W ATX power supply built for modern desktop PCs. It carries 80 PLUS Gold certification for high efficiency and lower running costs. Resonant LLC topology with DC-to-DC conversion delivers clean, stable power across all rails. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency.

Who this suits and who should look elsewhere

This unit suits builders assembling office workstations, home PCs or compact systems where quiet operation matters. The zero RPM fan mode stops the fan entirely at low and medium loads for near-silent running. Reduced coil whine further helps noise-sensitive environments. Builders needing more than 400 W for discrete graphics cards, heavy overclocking or multi-drive arrays should look at higher-capacity units.

80 PLUS Gold efficiency rating

The 80 PLUS Gold rating guarantees high efficiency at typical loads, reducing power draw, heat output and fan noise. This single specification determines whether the unit meets your efficiency and thermal targets for a given build.

Questions about this item

Is the 400W KHACHIMO P2H-5400V the only capacity available for this model?

The supplier lists this unit as a single 400W ATX power supply with no alternative wattages mentioned for the P2H-5400V.

What does the 80 PLUS Gold rating mean for daily use of this 400W unit?

It guarantees high efficiency at typical loads, so the PSU draws less power from the wall, runs cooler and keeps the fan quieter during normal operation.

How does the ATX form factor and Modern Standby support affect compatibility?

The standard ATX size fits most desktop cases, and Modern Standby compatibility allows the system to wake quickly from sleep while maintaining very low power draw.
