280W ATX Power Supply

The KHACHIMO PS-5281-01VF delivers 280 watts through a standard ATX form factor. It targets office PCs and compact builds that require Modern Standby support for rapid wake times and efficient low-load operation.

Installation and Common Issues

The unit fits regular ATX mounting points and uses standard connector layouts for straightforward installation. Builders should verify that the 280W ceiling covers every component, as undersized units can cause instability under load.

Pre-Order Checks

Confirm your chassis accepts a standard ATX power supply and that the total system draw stays within the rated output. The 80 PLUS Gold certification and Zero RPM fan mode reward efficient builds, but higher-power configurations will exceed this unit's capacity.

Questions about this item

How can I confirm the PS-5281-01VF is working correctly after installation?

The system should power on reliably, wake from sleep almost instantly thanks to Modern Standby support, and the fan should stay off during light loads due to Zero RPM mode.

What comes in the box with the KHACHIMO PS-5281-01VF and what must I source separately?

The unit itself is included; cables required for your specific motherboard, GPU and drives are not in the package.

Which 280 W version should I choose among the listed model numbers?

PS-5281-01VF is the ROHS-compliant revision; the other codes such as PC7001, 41A9701 or HK340-85FP are manufacturer cross-references for the same unit.
