500 W ATX power supply

The myVolts ATX-500W delivers 500 W of rated power for standard desktop builds. It uses a 20+4 pin motherboard connector and a 4+4 pin CPU connector. A manual 115 V/230 V input switch sets the mains voltage. Efficiency is specified above 80 %.

Basic desktop systems

This unit suits basic desktop systems with low energy consumption and low noise requirements. Automatic fan control adjusts speed based on the internal thermal sensor. Builders needing active PFC, higher wattage or modular cables should look elsewhere.

Manual voltage switching

The power supply requires the user to set the 115 V or 230 V input selector before connecting to mains. Incorrect setting can damage the unit or connected components. Verify the local mains voltage before installation.
