250W ATX power supply for basic desktops

The myVolts ATX-250W delivers 250W rated power for low energy consumption systems. It uses a manual 115/230V voltage selector and operates above 80% efficiency. A 12cm fan is regulated by an internal thermal sensor. The unit measures 140 x 150 x 86mm and includes a 1.1m power cord.

Check connectors and voltage before fitting

Confirm the motherboard accepts a 20+4 pin main connector and a 4 pin 12V CPU connector. Verify the chassis can accommodate the 140 x 150 x 86mm form factor. Ensure the mains supply matches the 115V or 230V selector setting. The supply provides two SATA, one 6 pin video card, and two fan connectors.

Replaces older AT units below 250W

This unit supersedes lower wattage AT power supplies lacking a 20+4 pin main connector or SATA power leads. The upgrade is worthwhile when the existing supply cannot power a 6 pin graphics card or lacks automatic fan control. Rated service life is 100000 hours with a hold up time exceeding 10ms.

Questions about this item

What cables come in the box and what must I buy separately?

The box contains the 250W power supply and a 1.1 metre power cord. All motherboard, CPU, SATA and video-card connectors are built into the unit, so no extra cables are required for a standard build.

The unit is rated at 250W — is that the right capacity for my low-power desktop?

The 250W rating suits basic desktops with low energy consumption. It delivers a 20+4 pin motherboard connector, a 4-pin CPU plug, two SATA ports and a 6-pin video-card plug, covering typical entry-level configurations.

What does the >80% efficiency figure mean when the supply is running in my PC?

At typical load the unit converts more than 80% of AC input into usable DC power, so less energy becomes heat. The thermal sensor then slows the 12 cm fan, keeping noise low during everyday use.
