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.

Questions about this item
How loud does the HK520-11PEP get when the PC runs all day?
The Zero RPM fan mode stops the fan completely at low and medium loads, and the resonant LLC topology with DC-to-DC conversion reduces coil whine for quieter operation.
What motherboard connection does the HK520-11PEP need to work?
The unit follows the ATX form factor and provides a standard 24-pin motherboard connector plus CPU EPS power for compatible boards.
Will the HK520-11PEP support Modern Standby sleep states on my older motherboard?
Modern Standby compatibility enables fast wake times and efficient low-load operation, but the motherboard and BIOS must also support the sleep state for it to function.
