How to use
Install the QOLTEC ATX 350W into a compatible ATX or compact ATX case following the case manufacturer’s mounting instructions. Connect the 20+4 pin ATX cable to the motherboard main power socket and attach the remaining fixed cables to storage drives, optical drives or other components as required. Ensure the system is powered off and disconnected from mains before connecting cables. After installation, connect the power supply to a 230 V / 50 Hz mains outlet and switch on the system. Verify fan operation and monitor system stability during initial power-up.
Usage recommendations
Use the power supply in a well-ventilated case and avoid blocking the 12 cm fan intake or exhaust.

Regularly check internal cabling for secure connections and keep the PSU and case dust-free to maintain cooling efficiency and low noise.
