PS-4321-1HD ATX power supply

The PS-4321-1HD is an ATX power supply certified to 80 PLUS Gold efficiency. It is suited to system builders who want lower power draw, reduced heat output and quiet operation in a modern desktop PC.

Check your build before ordering

Verify that your case accepts a standard ATX unit and that your motherboard uses a 24-pin main connector plus the required CPU and GPU power cables. Confirm the total system power draw fits within the unit’s rated capacity before purchase.

Integration and benefits

Resonant LLC topology with DC-to-DC conversion delivers stable voltages and enables modern standby sleep states with fast wake times. Zero RPM fan mode stops the fan at low and medium loads for silent running, while gold-rated efficiency cuts waste heat and electricity cost.
