KHACHIMO 300W ATX PS-6301-09 842936-001 Power Supply

300 W ATX Power Supply

The KHACHIMO PS-6301-09 is a 300 W ATX power supply built for modern desktop PCs that support Modern Standby sleep states. Its 80 PLUS Gold certification ensures high efficiency across typical loads, reducing waste heat and electricity draw. The resonant LLC topology with DC-to-DC conversion delivers clean, stable power to components while minimising coil whine. This unit suits builders who want efficient, quiet operation in a standard ATX form factor.

Compatibility Checklist

Verify that your case accepts a standard ATX power supply and that your motherboard uses a 24-pin main connector plus the required CPU and peripheral cables. Confirm the total system power demand stays within the 300 W rating, especially if you plan a discrete graphics card or many drives. Ensure the unit’s cable lengths reach all connectors in your chosen chassis layout. Buyers who need higher wattage for multi-GPU setups or extreme overclocking should look elsewhere.

Thermals, Noise and Power Draw

The Zero RPM fan mode keeps the cooling fan completely stopped at low and medium loads, providing near-silent operation during everyday tasks. When the fan does spin, the high efficiency of the 80 PLUS Gold design means less waste heat is produced, so the fan can run at lower speeds. Resonant LLC topology further reduces coil whine for a quieter electrical profile. Under normal desktop workloads the unit runs cool and quiet while maintaining stable voltages.
