  • TypeATX
  • Faster wake from sleep with Modern Standby support

Compact 250W ATX power supply

The KHACHIMO MATX-250-3 is a 250 watt ATX power supply built for small-form-factor systems. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep. Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine. A zero-RPM fan mode stops the fan at low and medium loads for near-silent running.

Ideal for low-power builds; not for high-draw GPUs

This unit suits office PCs, home-theatre boxes or embedded appliances that stay well within a 250 watt envelope. The Gold-rated efficiency and silent fan profile benefit noise-sensitive environments. Builders planning a discrete graphics card or a CPU with a high thermal design power should look at higher-capacity models because this supply cannot deliver the extra current those components require.

80 PLUS Gold efficiency rating

The 80 PLUS Gold badge confirms high efficiency across typical loads, lowering electricity draw, heat output and acoustic noise. This single specification is the clearest indicator of whether the unit matches a build’s power-quality and thermal targets.
