Compact ATX power supply for small-form-factor

This 250 W unit fits standard ATX dimensions while delivering enough output for low-power desktops and office machines. It targets system integrators and DIY builders who need a reliable, space-saving power source without the bulk of higher-wattage models.

80 PLUS Gold efficiency rating

The Gold certification confirms high conversion efficiency across typical loads, reducing waste heat and lowering electricity draw. This single figure determines whether the unit meets the energy and thermal requirements of a compact chassis.

Straightforward ATX installation

The power supply mounts using standard ATX screw holes and connects with the usual motherboard and peripheral cables. Zero RPM fan mode keeps the unit silent at low and medium loads, while the resonant LLC topology with DC-to-DC conversion minimises coil whine; builders should verify that the 250 W ceiling matches their component power budget before fitting.

Questions about this item

What does the 250W rating mean for the components I can run?

It sets the maximum continuous power the unit can deliver to the motherboard, CPU, GPU and drives combined; a system drawing more than 250W will shut down or become unstable.

How does the ATX form factor limit where this supply fits?

It follows the standard ATX dimensions and mounting holes, so it installs in any case designed for ATX power supplies but will not fit SFX or TFX chassis.

What clearance do I need at the rear for the fan and cable plug?

The rear-mounted fan and fixed AC inlet require a few centimetres of free space behind the case for airflow and the power cord bend radius.
