Basic desktop power supply

The myVolts ATX-500W delivers 500W rated output for entry-level systems that prioritise quiet operation. Clearly labelled connectors simplify the build process. A 12cm fan adjusts speed automatically via an internal thermal sensor. Efficiency exceeds 80 percent under load.

Upgrade from older AT units

This unit replaces legacy AT power supplies with a modern 20+4 pin motherboard connector and dual 4-pin CPU power leads. The jump is worthwhile when a system needs SATA power for multiple drives and a 6-pin to 6+2-pin graphics lead. Manual 115V/230V input switching covers both mains standards.

Capacity and headroom

Four SATA connectors and one graphics adapter support a modest drive count and a single mid-range GPU. The 500W ceiling and 10ms hold-up time suit low-consumption workloads. Continuous loads beyond the rated figure or multi-GPU configurations will exceed the design envelope.
