850W ATX Power Supply for Modern Standby Builds

This 850W ATX power supply targets system builders who need reliable output for modern desktops and workstations. It supports Modern Standby for rapid wake-from-sleep behaviour and improved low-load efficiency. The unit is new and carries an 80 PLUS Gold certification for reduced power draw and heat.

80 PLUS Gold Efficiency Rating

The single specification that determines suitability is the 80 PLUS Gold certification, confirming high efficiency across typical loads. This translates to lower electricity consumption, less waste heat and quieter operation. Builders who require this efficiency tier should verify it matches their component power budget.

LLC Topology with Zero RPM Fan Mode

A resonant LLC topology with DC-to-DC conversion delivers clean power and enables deeper sleep states while reducing coil whine. The Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent running. Ensure the case provides standard ATX mounting and that your components use the connectors supplied with this unit.
