865W ATX Power Supply for Modern Standby Systems

The KHACHIMO PWS-865-PQ delivers 865W of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency and supports Modern Standby for rapid wake-from-sleep performance. Resonant LLC topology with DC-to-DC conversion ensures clean power delivery and reduced coil whine.

Verify ATX Clearance and Connector Requirements

Confirm your chassis accepts a standard ATX power supply and that the included cable set matches your motherboard, CPU and GPU power connectors. Ensure the case provides adequate airflow for the unit's cooling fan when it spins up under heavier loads. Check that your motherboard supports Modern Standby to use the fast wake feature.

Replaces Lower-Efficiency or Noisier ATX Units

This unit upgrades from power supplies lacking 80 PLUS Gold efficiency or zero-fan operation, cutting power draw and idle noise. The jump is worthwhile when building a Modern Standby system or when coil whine and fan noise at low load are primary concerns. It is not suited for builds requiring higher wattage than 865W.
