500 W ATX power supply for basic desktops

This And 1 ATX-500W unit delivers 500 W of rated power for standard desktop builds. It uses a manual 115/230 V voltage switch and achieves over 80 % efficiency. A 12 cm fan is regulated by an internal thermal sensor for automatic speed control. Clear labelling on the connectors makes installation quick and effective.

Suited for low power quiet systems not high end

The supply fits low energy consumption, low noise basic desktop systems that need a 20+4 pin motherboard connector, a 4+4 pin CPU connector, four SATA connectors and a 6 pin to 6+2 pin video card connector. It is not for builders who need active PFC, higher efficiency certification or multiple GPU power cables.

Single 12 V rail with 4+4 pin CPU connector

The unit provides a single 12 V rail design and includes a 4+4 pin CPU 12 V interface alongside the 20+4 pin main connector. This combination determines whether the power supply matches the motherboard and processor power requirements of the intended build.

Questions about this item

How do I install the 20+4 pin motherboard and dual 4-pin CPU connectors, and what step is often missed?

Connect the 20+4 pin plug to the motherboard, then attach both 4-pin CPU cables to the 8-pin socket; the step often missed is setting the 115/230V switch to match local mains before powering on.

What maintenance or replacement will this unit need later?

The 12 cm fan is the only moving part; after long use it may need cleaning or replacement, and the 100000 hour service life rating gives a rough guide for when to plan a full unit swap.

What limit appears first under sustained load?

The manual 115/230V switch and lack of active PFC mean efficiency drops above 80% and heat rises quickly, so thermal protection will throttle the fan speed before the 500W rating is sustained continuously.
