280 W ATX power supply

The KHACHIMO ACE-828M-RS delivers 280 watts of continuous power in a standard ATX form factor. It targets office PCs, small-form-factor builds and basic home systems that require reliable, efficient energy delivery without excess capacity.

Ideal for low-power desktops and upgrades

Suits builders assembling compact workstations or replacing a failed unit in a pre-built chassis where a modest 280 W budget is sufficient. Not intended for configurations with discrete graphics cards, multi-drive arrays or overclocked processors that demand higher sustained output.

80 PLUS Gold efficiency with Zero RPM mode

Certified 80 PLUS Gold, the unit maintains high efficiency across typical loads to reduce heat and electricity draw. A Zero RPM fan mode stops the fan completely at low and medium loads, while resonant LLC topology and DC-to-DC conversion minimise coil whine and support modern standby sleep states.
