How to use

Install the ASUS Prime -850G into a compatible ATX case, secure it to the PSU mounting points, and connect the 20+4 pin ATX cable to the motherboard. Attach the included CPU, PCIe, SATA and Molex cables to the corresponding components, ensuring all connectors are fully seated. Verify correct input voltage and power on the system; monitor voltages and system stability during initial use. Observe standard safety practices: disconnect mains power before making internal connections and avoid obstructing the fan intake and exhaust paths.

Recommendations

Match the power supply to your system’s cumulative power draw with headroom for peak loads; for multi-GPU or highly overclocked configurations, plan for additional capacity. Keep ventilation clear and perform periodic dust removal to preserve cooling efficiency and prolong fan life.
