KHACHIMO YM-5411B 405W ATX Power Supply

The KHACHIMO YM-5411B is a 405W ATX power supply certified 80 PLUS Gold for high-efficiency operation. It features Resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power while reducing coil whine. Modern Standby compatibility ensures extremely fast wake-from-sleep times and improved low-load efficiency. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation.

Ideal for efficiency-focused builds

This unit suits builders who prioritise high efficiency, low noise, and modern sleep-state support in a 405W ATX form factor. The Gold certification and Zero RPM mode benefit systems that run at low loads for extended periods. Builders requiring higher wattage for multi-GPU configurations or extreme overclocking should look at higher-capacity units instead.

405W Gold-certified ATX capacity

The single specification that decides fit is the 405W continuous power rating combined with 80 PLUS Gold certification. This capacity targets mainstream desktop builds with single graphics cards and standard component counts. Verify your system's total power draw against this 405W limit before purchasing to ensure adequate headroom for stable operation.
