KHACHIMO HK520-11PEP 420W ATX Power Supply

Efficient ATX Power Supply

The KHACHIMO HK520-11PEP delivers 420W of continuous power through a standard ATX form factor. It holds 80 PLUS Gold certification for high efficiency, reducing waste heat and lowering energy consumption. Resonant LLC topology with DC-to-DC conversion provides clean, stable voltage rails for modern components. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency.

Quiet Builds and Modern Sleep States

This unit suits builders who prioritise low noise, as the Zero RPM fan mode stops the cooling fan entirely at low and medium loads. It also fits systems that rely on Modern Standby for instant resume and efficient sleep states. Buyers who need more than 420W of output for high-end graphics cards or multi-GPU configurations should look at higher-capacity units. Systems requiring specialised server-grade redundancy or non-ATX form factors are not addressed by this design.

420W Gold-Certified Output

The single specification that decides fit is the 420W rated capacity combined with 80 PLUS Gold efficiency. This power level supports mainstream CPUs and mid-range graphics cards while keeping operating costs and heat low. Verifying your build's total power draw against this 420W limit determines whether this supply is the right part.
