250W ATX desktop power supply

The myVolts ATX-250W delivers 250 watts of continuous power for basic desktop computers. It targets office PCs and simple workstations that do not require high-output graphics cards or multiple drives. The unit includes a 1.1 metre mains cord and a manually selectable 115/230 volt input switch for worldwide use.

20+4 pin motherboard and 4 pin CPU connectors

The power supply provides a 20+4 pin ATX connector for the motherboard and a dedicated 4 pin 12 volt CPU connector. These two interfaces decide whether the unit fits your board; it lacks an 8 pin EPS connector and PCIe 8 pin graphics connectors. Builders needing those connections must choose a different model.

Labelled cables and automatic fan control

Clearly marked connectors make cable routing straightforward for first-time builders. A thermal sensor adjusts the 12 centimetre fan speed automatically, keeping noise low under light loads. The supply has no active PFC and only two SATA power plugs, so systems with many drives or modern high-efficiency requirements may find it limiting.
