  • Product typeATX
  • Fast wake-from-sleep with Modern Standby support

  • Fan stops completely at low loads for silent running
  • LLC resonant topology with DC-to-DC delivers clean power

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.

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.
