400W ATX Power Supply

The KHACHIMO P2H-6400P is a 400W ATX power supply built for modern desktop systems. It carries 80 PLUS Gold certification for high efficiency and lower running costs. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power to components. Modern Standby compatibility enables extremely fast wake-from-sleep times.

Suitable builds and limits

This unit suits builders who want quiet operation through a Zero RPM fan mode that stops the fan at low and medium loads. It also fits systems that rely on Modern Standby sleep states for quick resume. Buyers needing more than 400W of continuous power should look at a higher-capacity model instead.

80 PLUS Gold efficiency

The 80 PLUS Gold rating is the single specification that decides whether this is the right part. It guarantees high efficiency operation for lower power consumption, less noise, and cooler temperatures under typical loads.

Perguntas sobre este artigo

How quiet is the P2H-6400P when the system runs all day under light load?

The Zero RPM fan mode stops the fan completely at low and medium loads, so the unit runs silently during typical daily use.

Which motherboard power connectors does the 400 W ATX unit require to be present?

It uses the standard 24-pin ATX and 4+4-pin EPS connectors that every modern ATX motherboard provides.

Will the 80 PLUS Gold efficiency work with an older motherboard that lacks Modern Standby support?

Yes, the efficiency rating and LLC resonant topology function normally; Modern Standby features simply remain inactive on legacy boards.
