400 W ATX Gold PSU

The Khachimo Jumper400 is a 400 W ATX power supply certified to 80 PLUS Gold efficiency. It uses resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power while reducing coil whine. Modern Standby compatibility enables extremely fast wake-from-sleep transitions and better low-load efficiency. This unit suits standard desktop builds that prioritise quiet, efficient operation.

Builders wanting silent Gold efficiency

Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running, making the supply a strong choice for living-room or office PCs where noise matters. Modern Standby support benefits users who rely on instant resume from sleep states. Systems needing higher wattage or multiple discrete GPU power connectors should look elsewhere because this unit provides only 400 W total output.

400 W continuous output

The single specification that decides fitment is the 400 W continuous power rating. Verify that the complete system draw under full load stays within this limit before purchasing.

Questions about this item

What cables come in the box and which ones must I buy separately?

The power supply ships with the fixed ATX motherboard cable, CPU power cable, PCIe connectors and peripheral leads included; no extra cables are required for a standard build.

How do I decide which wattage version to choose?

This model is offered only in the 400 W rating, so select it if your total system draw stays below that figure.

What does the 80 PLUS Gold rating actually deliver once the unit is installed?

It guarantees at least 80 % efficiency at typical loads, which reduces power draw, heat output and fan noise compared with lower-rated units.
