Capacity and purpose

The myVolts ATX-500W delivers 500W of rated power for low energy consumption desktop systems. It uses a manual 115/230V input switch and a thermal sensor that controls the 12cm fan speed automatically. A 1.1meter power cord is included in the package.

Connections and fit

Check that your case can accommodate a unit measuring 140 x 150 x 86mm. The motherboard connector is a 20+4 pin layout while the CPU power uses a 4+4 pin arrangement. Four SATA connectors and a 6 pin to 6+2 pin video card lead are provided alongside two fan headers.

Sustained operation

Efficiency is rated above 80% and hold-up time exceeds 10ms to ride through brief mains interruptions. The supplier quotes a service life of 100000 hours for the unit. The thermal sensor adjusts fan speed continuously rather than only during short load spikes.

Perguntas sobre este artigo

What cables and connectors come in the box with the ATX-500W?

The package includes the power supply unit and a 1.1 metre power cord; the unit itself provides a 20 + 4 pin motherboard connector, two 4 pin CPU connectors, four SATA connectors and a 6 pin to 6 + 2 pin video card connector

The spec shows manual 115/230 V switching and no active PFC — does that limit which builds can use it?

The supply is designed for low energy, low noise basic desktop systems and requires the user to set the input voltage switch to match the local mains supply

How does the 500 W rating translate to real-world use with the > 80 % efficiency figure?

At typical loads the unit delivers up to 500 W total output while drawing roughly 20 % more from the wall, and the thermal sensor adjusts the 12 cm fan speed to keep noise low
