500W ATX power supply for basic desktops

The myVolts ATX-500W delivers 500W rated output with manual 115V/230V switching and >80% efficiency. It targets basic desktop systems that demand low energy consumption and low noise. A thermally controlled 12cm fan adjusts speed automatically. The unit is built from high-quality materials for a 100000-hour lifespan.

Standard ATX fit with colour-coded connectors

Installation follows the standard ATX form factor measuring 140 x 150mm with 12mm depth. Clearly marked connectors include a 20+4 pin motherboard plug, dual 4+4 pin CPU power, four SATA and a 6-pin to 6+2-pin graphics lead. The colour coding makes routing quick and reduces the risk of reversed insertion. No active PFC is present, so the voltage selector must match the mains supply before power-on.

Manual voltage selector decides regional

The single specification that determines suitability is the manual 115V/230V input switch. Builders must set this correctly for their local mains voltage or the unit will not operate safely. All other connectors and dimensions follow common ATX norms.

Questions about this item

How can I verify the ATX-500W is working correctly after installation?

The 12 cm fan should spin up and its speed will adjust automatically via the internal thermal sensor; the unit delivers 500 W with >80 % efficiency and a hold-up time above 10 ms.

What comes in the box and which cables or components must I purchase separately?

The package includes the power supply and one power cord; the unit provides a 20+4 pin motherboard connector, 4+4 pin CPU connector, four SATA connectors, one 6-pin to 6+2 pin graphics connector and two fan headers.

Which version of the ATX-500W should I choose for my region's mains voltage?

The single model operates on both 115 V and 230 V input via a manual voltage switch, so no separate regional version is required.
