280W ATX Power Supply for Standard Builds

The KHACHIMO PS-5281-02VA is a 280W ATX power supply built for everyday desktop systems. It carries 80 PLUS Gold certification, meaning high efficiency that lowers power draw and heat. Modern Standby compatibility enables extremely fast wake-from-sleep times. A Zero RPM fan mode stops the fan at low and medium loads for near-silent operation.

Suits Efficiency-Focused Low-Power Systems

This unit fits builders who want Gold-rated efficiency and quiet running in a modern ATX chassis. The LLC resonant topology with DC-to-DC conversion delivers clean power and reduces coil whine. Buyers needing more than 280W for discrete graphics cards or multi-drive arrays should select a higher-capacity model instead.

280 Watt Continuous Output Decides Fit

The single specification that determines compatibility is the 280W rated output. Match this figure against the total power draw of your CPU, motherboard, drives and any add-in cards. If the combined load exceeds this rating, the supply cannot safely power the system.
