KHACHIMO ZKS-450SX 450W ATX power supply

450 W ATX power supply

The KHACHIMO ZKS-450SX delivers 450 W of continuous power in a standard ATX form factor. It targets builders who need a compact, efficient unit for modern desktop platforms. The design supports Modern Standby for rapid wake-from-sleep behaviour. It suits general productivity and light gaming systems.

450 W capacity with 80 PLUS Gold headroom

The 450 W rating comfortably handles mainstream CPUs and mid-range graphics cards under typical loads. Peak demands from high-end multi-GPU arrays or extreme overclocking will exceed the available headroom. The 80 PLUS Gold certification ensures high efficiency across the load range. Efficiency drops sharply only when the unit is pushed beyond its rated maximum.

Zero RPM fan mode and LLC topology

A Zero RPM mode stops the fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion supplies clean power and reduces coil whine. The combination keeps temperatures lower and acoustic output minimal during everyday use. Fan noise becomes audible only under sustained heavy load.
