KHACHIMO PRM320-1 320W ATX Power Supply

PRM320-1 320W ATX Power Supply

The PRM320-1 is a 320W ATX power supply built for modern desktop builds. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power while reducing coil whine. A Zero RPM fan mode stops the fan at low and medium loads for near-silent operation.

Best for efficient low-power builds

This unit suits compact or office systems where quiet running and high efficiency matter more than high wattage. Builders planning multi-GPU configurations, high-end graphics cards or heavy overclocking should look at higher-capacity power supplies instead. The 320W limit also rules out workstations with many drives or expansion cards that draw sustained power.

320W capacity with Gold headroom

The 320W rating comfortably handles mainstream CPUs, integrated graphics and a single mid-range discrete card under typical loads. Gold-rated efficiency keeps waste heat and electricity use low across the load range. Headroom disappears when the system approaches sustained loads near the rated maximum, at which point the fan will spin up and voltage regulation tightens to its limits.
