KHACHIMO R320 350W ATX power supply 80 PLUS Gold

350 W ATX power supply for efficient builds

This KHACHIMO R320 unit delivers 350 W through a standard ATX form factor and carries 80 PLUS Gold certification for high efficiency. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine. It suits builders assembling office PCs or compact systems that prioritise quiet, efficient operation.

Check your power budget and cable needs

Verify that the 350 W capacity covers the combined draw of your CPU, graphics card, storage and peripherals before ordering. Confirm that your motherboard uses a standard 24-pin ATX connector and that your CPU power socket matches the EPS or 4-pin cable supplied with this unit. Ensure your case accepts a regular ATX-sized supply and that the fixed cable set reaches every component without strain. Builders who need more power headroom or modular cables should consider a higher-wattage alternative.

Gold-rated efficiency with semi-passive cooling

The 80 PLUS Gold rating means lower power consumption, less waste heat and cooler internal temperatures under typical loads. Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation during everyday tasks. Resonant LLC topology with DC-to-DC conversion further suppresses coil whine and supports deeper, more energy-efficient sleep states. Fixed cables keep the interior tidy in smaller cases where excess length would obstruct airflow.
