KHACHIMO 120W ATX Power Supply YH-5301K YM-2301K

120W ATX Power Supply

The KHACHIMO YH-5301K is a 120W ATX switching power supply designed for low-power desktop systems. It suits office PCs, compact builds or upgrades where a modest, efficient unit is required. The unit carries 80 PLUS Gold certification for high efficiency across typical loads. It is not for builders who need more wattage for discrete graphics cards or multi-drive arrays.

ATX Standard and Efficiency Limits

The ATX form factor ensures mechanical compatibility with standard cases and motherboards, while the 120W rating caps the total continuous output available to components. 80 PLUS Gold certification guarantees at least 80 per cent efficiency at defined load points, reducing waste heat and electricity draw. The supply does not support higher-wattage configurations or auxiliary connectors beyond what the 120W design provides.

Installation and Common Issues

Installation follows the usual ATX procedure: mount the unit, connect the 24-pin main cable and any peripheral leads, then secure the AC cord. Zero RPM fan mode keeps the system silent at low loads, though the fan will spin up under sustained demand. Builders sometimes find the fixed cable set limits routing options in very small chassis. Ensure the total system draw stays within the rated output to avoid shutdowns.
