320W ATX Power Supply for Modern Standby Builds

This KHACHIMO unit delivers 320 watts of continuous power through a standard ATX form factor. It is suited for compact office PCs, home-theatre systems or low-power workstations that rely on fast sleep and wake cycles. The 80 PLUS Gold certification ensures high efficiency across typical load ranges. Modern Standby compatibility allows the system to enter and exit low-power states almost instantly.

Check ATX Clearance and Connector Needs

Verify that your chassis accepts a standard ATX power supply and that the motherboard uses a 24-pin main connector plus the required CPU and peripheral cables. The 320W rating limits the unit to platforms with modest graphics or integrated graphics only. Builders planning discrete mid-range or high-end GPUs should look for a higher-wattage model. Ensure the cable lengths reach all drive and motherboard positions in your case layout.

Gold Efficiency with Zero-RPM Fan Mode

At low and medium loads the cooling fan stops completely, providing near-silent operation for media playback or office tasks. Resonant LLC topology with DC-to-DC conversion delivers clean voltage regulation and reduces coil whine. The 80 PLUS Gold rating keeps waste heat low, so internal case temperatures stay manageable even during sustained workloads. Overall power draw from the wall remains minimal thanks to the high-efficiency design.
