350W ATX power supply

The KHACHIMO YM-6351Q is a 350W ATX power supply built for modern desktop systems. It targets builders who want certified efficiency and quiet operation in a standard form factor.

80 PLUS Gold and Zero RPM fan

Gold-certified efficiency reduces waste heat and keeps internal temperatures lower. The Zero RPM mode stops the fan completely at low and medium loads, while resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine.

Modern Standby sleep support

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. Systems that rely on deeper sleep states benefit, but builds needing higher continuous output or multiple high-power graphics cards should consider a larger unit.
