280W ATX Power Supply

The KHACHIMO M58 57 delivers 280 watts of continuous power in a standard ATX form factor. It suits office workstations, small-form-factor desktops or legacy system upgrades where a compact, efficient unit is required.

Gold Efficiency and Silent Cooling

80 PLUS Gold certification reduces wasted energy and keeps operating temperatures lower. A Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running, while resonant LLC topology with DC-to-DC conversion minimises coil whine and supports deeper sleep states.

Modern Standby Ready

Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. This makes the unit suitable for systems that rely on instant resume, but it will not satisfy builds needing higher wattage or additional PCIe power connectors.

Highlights

  • Fast wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Fan stops completely at low loads for silent running
  • LLC resonant topology with DC-to-DC delivers clean power

Questions about this item

Does the ATX form factor of this 280W unit limit the power available to high-end graphics cards?

The ATX design follows the standard 12 V rail distribution, but the 280 W total capacity restricts use to entry-level GPUs or integrated graphics rather than high-end cards.

Will the standard ATX dimensions fit inside a slim or small-form-factor case?

This supply uses the regular ATX footprint, so it requires a case with a full-size PSU bay; it will not fit slim or SFX-only enclosures.

Do I need to enable anything in the BIOS for Modern Standby to work after installing this PSU?

After fitting the unit and connecting the 24-pin and CPU power cables, enable Modern Standby in the motherboard firmware so the fast wake and low-load efficiency features activate.
