KHACHIMO 255W ATX Power Supply 80 PLUS Gold

255W ATX Power Supply for Modern Standby PCs

This KHACHIMO unit delivers 255 watts of continuous power through a standard ATX form factor. It targets system builders and upgraders who need an 80 PLUS Gold certified supply for compact or office-oriented desktops that rely on Modern Standby sleep states. The resonant LLC topology with DC-to-DC conversion keeps output stable across varying loads.

Straightforward ATX installation

Fitting the supply follows the usual ATX mounting pattern and connector layout, so most builders will find it routine. The Zero RPM fan mode stops the fan completely at low and medium loads, which is quiet but can be mistaken for a fault if the fan does not spin during a quick test. Ensure the motherboard power and CPU power cables seat firmly to avoid intermittent boot issues.

Suits efficiency-focused builds.

This unit suits compact desktops, business PCs, or upgrades where 80 PLUS Gold efficiency and Modern Standby support matter more than raw output. Builders planning discrete graphics cards, multiple drives, or heavy overclocking should look at higher-wattage supplies because the 255 watt limit leaves little headroom for power-hungry components.
