KHACHIMO QFX5100 QFX5200 45W 80 PLUS Gold ATX power supply

KHACHIMO 45 W ATX power supply

This 45 watt ATX unit carries 80 PLUS Gold certification for high efficiency across typical loads. Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. A zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation.

Verify ATX fit and cable needs

Confirm your chassis accepts a standard ATX power supply and that the included cables reach every component you plan to power. Check that the 45 watt capacity covers the combined draw of your CPU, graphics card, storage and peripherals under full load. Ensure the motherboard and GPU connectors supplied match your hardware before ordering.

Suits low-power silent builds

Ideal for compact or office systems where low noise and efficient sleep states matter. Builders needing higher wattage for discrete graphics cards, multiple drives or overclocked processors should look at higher-capacity units. Systems requiring specialised form factors such as SFX or TFX must choose a different chassis-compatible model.
