300 W ATX power supply

The KHACHIMO ST-300UAG-05E is a standard ATX power supply rated at 300 W. It suits basic desktop builds or replacement of a failed unit in office and home PCs. The unit has been tested and confirmed working before shipment. It provides essential power for low-demand systems without extra connectors or modular cables.

Simple ATX installation

Installation follows the usual ATX procedure: mount the unit with four screws, connect the 24-pin motherboard plug and the 4-pin CPU plug, then attach any peripheral cables needed. The fixed cable set means unused leads must be tucked away, which can be awkward in very small cases. Builders needing higher wattage, multiple GPU connectors or modular cabling should choose a different unit.
