280 W ATX power supply for modern standby PCs

This 280 W ATX unit is built for systems that use Modern Standby sleep states. It suits office workstations, compact home PCs and any build that needs fast wake times and high efficiency at low load.

Standard ATX fit with zero-RPM fan mode

The supply follows the ATX form factor, so it mounts in any compatible case using four screws and connects with the usual 24-pin and CPU cables. At low and medium loads the fan stops completely, eliminating noise; coil whine is further reduced by the resonant LLC topology with DC-to-DC conversion.

280 W rated output

The single deciding specification is the 280 W maximum continuous power. Systems with discrete graphics cards, multiple drives or high-core-count CPUs will exceed this limit and need a higher-capacity unit.
