KHACHIMO S5500 S5560 150W ATX Power Supply

150W ATX power supply for basic builds

The KHACHIMO S5500 S5560 delivers 150 W of continuous power through a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency at typical loads. Modern Standby compatibility enables rapid wake-from-sleep and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion supplies clean power and reduces coil whine.

Suits compact office PCs and low-power upgrades

This unit fits systems built around low-wattage processors and integrated graphics where a 150 W ceiling is sufficient. The zero-RPM fan mode keeps acoustics near silent during light workloads. Builders needing discrete graphics cards, multiple drives or higher sustained loads should consider a higher-capacity supply. It is not intended for gaming workstations or multi-GPU configurations.

150 W capacity with Gold-rated headroom

At full rated load the supply maintains Gold-level efficiency, reducing waste heat and fan speed. The DC-to-DC design keeps minor rails stable for modern sleep states. Headroom disappears quickly if a dedicated GPU or many peripherals are added. Continuous operation near the 150 W limit will engage active cooling and reduce acoustic advantage.
