500 W ATX power supply for basic desktops

This 500 W ATX power supply is designed for basic desktop systems with low energy consumption and low noise. Manual 115 V/230 V switching allows use in different mains regions. Efficiency exceeds 80 %. The red silent fan runs under thermal sensor control for quiet operation.

Clearly marked connectors and robust build

The unit uses high-quality materials and strict quality control for a long service life of 100000 hours. Motherboard power is provided by a 20+4 pin connector alongside dual 4 pin CPU 12 V plugs. Four SATA connectors and a 6 pin to 6+2 pin graphics adapter cover drives and a mid-range card. Two fan headers are also included.

Check manual voltage switch and hold-up time

Verify the input voltage selector matches your local mains before powering on. Hold-up time is rated above 10 ms, which may be short for areas with unstable power. The physical size is approximately 140 x 150 x 12 mm, so confirm it fits your chassis. No active PFC is present.

Questions about this item

Does the manual 115/230V switch limit the unit to 80% efficiency?

The supply is rated above 80% efficiency; the manual voltage selector does not change that figure.

Will the 140 x 150 mm chassis fit a standard ATX case?

At 140 mm wide by 150 mm deep it matches the common ATX footprint, but verify your case clearance before mounting.

How do I connect the 20+4 pin motherboard plug without bending pins?

Align the keyed connector, press straight in until the latch clicks, and do not force the extra four pins if your board uses only 20.
