KHACHIMO 300W ATX Power Supply

The KHACHIMO T3630 3640 is a 300W ATX power supply built for modern desktop systems. It carries 80 PLUS Gold certification for high efficiency, reducing power draw and heat output. Modern Standby compatibility ensures extremely fast wake-from-sleep transitions and improved low-load performance.

Ideal for efficient office PCs.

This unit suits compact or office desktops that benefit from silent operation and low energy consumption. The Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent running. Builders needing more than 300W for discrete graphics cards or heavy workloads should look at higher-capacity alternatives.

Resonant LLC with DC-to-DC topology

The resonant LLC design paired with DC-to-DC conversion delivers clean, consistent power while reducing coil whine. This topology also enables more energy-efficient sleep states, supporting the Modern Standby feature. It is the core engineering choice that defines the unit's quiet, stable character.
