KHACHIMO 250W ATX Power Supply MPW250-28A

250W ATX Power Supply for Modern Standby

The KHACHIMO MPW250-28A is a 250W ATX power supply built for systems that use Modern Standby. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power while supporting efficient sleep states. The 28A rating on the main rail provides stable output for typical desktop components.

Suited for compact or efficiency-focused builds

This unit suits builders who want low power draw, quiet operation and fast wake-from-sleep behaviour in a standard ATX form factor. The Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running. Systems that demand higher continuous wattage or multiple high-power graphics cards should look at a higher-capacity supply.

Sustained load behaviour with Gold efficiency

Under sustained load the resonant LLC topology with DC-to-DC conversion maintains tight voltage regulation and reduces coil whine. The 80 PLUS Gold rating ensures high efficiency across the load range, keeping temperatures lower and fan speeds down. Zero RPM mode remains inactive during heavy demand, allowing active cooling to handle the thermal output.
