KHACHIMO 380 gen10 500W ATX Power Supply

The KHACHIMO 380 gen10 is a 500 watt ATX power supply built for desktop PCs. It carries 80 PLUS Gold certification and supports Modern Standby for fast wake-from-sleep and better low-load efficiency. The unit uses resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power.

Suited for efficient desktop builds

This supply fits builders who want high efficiency, lower power draw and reduced noise thanks to a zero RPM fan mode that stops the fan at low and medium loads. It is not for systems that need more than 500 watts of continuous power, nor for compact form factors requiring SFX or TFX dimensions.

500 watt ATX output with Gold efficiency

The single deciding specification is the 500 watt ATX rating combined with 80 PLUS Gold certification, which determines whether the unit can meet the power budget and efficiency target of the intended build.

Questions about this item

Which KHACHIMO 380 gen10 500W variant matches my HP server part number?

The unit covers HP part numbers 865408-b21, 865398-001, 866729-001 and 865399-201, so match the label on your existing supply to confirm compatibility.

What does the 500W rating mean for my system build?

It delivers up to 500 watts of continuous power with 80 PLUS Gold efficiency, so a typical mid-range GPU and CPU combination will run well within its limits while wasting less energy as heat.

Is the ATX form factor the only fitment I need to check?

Yes, the supply uses the standard ATX footprint, but verify your chassis has room for the unit's depth and that your motherboard uses the usual 24-pin and CPU power connectors.
