  • 280W ATX power supply supports modern energy-efficient sleep states

280W ATX power supply for compact builds

This 280W ATX unit fits standard chassis dimensions and targets small-form-factor PCs, office workstations and media-centre systems. It delivers enough headroom for integrated graphics or entry-level discrete cards while keeping the power budget modest.

80 PLUS Gold efficiency with zero-RPM fan

Gold-rated efficiency cuts waste heat and electricity draw, and the resonant LLC topology with DC-to-DC conversion keeps output stable while reducing coil whine. At low and medium loads the fan stops completely, giving near-silent operation during everyday tasks.

Modern Standby support replaces older sleep states

The supply enables Modern Standby for near-instant wake times and deeper low-power sleep, a clear step up from legacy S3 suspend. Builders moving from basic Bronze units or non-Modern-Standby designs will notice quieter idle behaviour and faster resume, but systems needing more than 280W or multiple high-power GPU connectors should look elsewhere.
