How to use

Install the PSU into a compatible ATX chassis and connect the 24-pin ATX motherboard cable and required modular cables for CPU, GPU and storage devices. Use the included PCIe 12+4 pin cable for compatible graphics cards, following the GPU manufacturer's recommended power requirements. Ensure proper ventilation around the 120 mm fan and secure all connectors before powering on the system. Verify AC input matches the local mains (100–240 V) and set any required PSU switches according to your region if present.

Recommendations

Follow GPU manufacturer guidelines when using the PCIe 12+4 pin cable and size your overall system power accordingly; recommended wattage marked on the connector is an estimation and actual system demand may vary with components and usage.
