500W ATX power supply for basic desktops

This myVolts ATX-500W unit delivers 500W of rated power for low energy consumption office and home systems. It uses a 20+4 pin motherboard connector, dual 4-pin CPU power, four SATA connectors and a 6-pin to 6+2-pin video card connector. A 12cm fan is regulated by an internal thermal sensor. The 1.1 metre power cord is included.

Replaces older ATX units without active PFC

The supply relies on manual 115/230V switching rather than active power factor correction. Efficiency is rated above 80 percent with a hold-up time exceeding 10ms. The upgrade makes sense when a system needs the stated connectors and can operate without active PFC. It is not suited for builds that require active PFC or higher efficiency certification.

Suits low-noise office and home PCs

Builders assembling basic desktops with modest graphics will find the connector set and automatic fan control adequate. Buyers who need active PFC, modular cables or power for high-end graphics cards should look at something else.

Questions about this item

Will the 140 x 150 x 86mm case fit a standard ATX chassis?

The unit measures 140 x 150 x 86mm, matching the standard ATX form factor, so it fits most desktop cases that accept ATX power supplies.

Which connectors must be attached during installation, and which step is often missed?

Connect the 20+4 pin motherboard cable, the 4+4 pin CPU cable, four SATA drives, and the 6-pin to 6+2 pin GPU cable; the 115/230V selector switch must be set before powering on.

What is the expected service life and which part wears out first?

The supply is rated for 100000 hours; the 12cm fan is the primary moving component and will likely need replacement before the electronics.
