DC 48V 275W ATX power supply

This ATX power supply delivers 275 watts from a 48 volt DC input. It is built for compact systems, embedded PCs or industrial chassis that run on DC power rather than mains AC. The unit fits a standard ATX footprint while accepting a single DC source.

80 PLUS Gold efficiency and DC input limits

The 80 PLUS Gold certification means high efficiency across typical loads, reducing waste heat and fan noise. Because the unit draws from a 48 volt DC rail, the source must supply sufficient current for the full 275 watt output plus conversion losses. Long cable runs or undersized wiring can cause voltage drop that triggers protection shutdowns.

275 watt capacity with Modern Standby support

The 275 watt rating covers CPU, GPU, drives and peripherals in a single DC-powered build. Modern Standby compatibility allows very fast wake from sleep and low idle draw. Zero RPM fan mode keeps the unit silent at light loads. Systems needing more than 275 watts or multiple high-power GPUs will exceed this unit’s headroom.
