Troubleshooting

Problem	Possible Cause	Solution
Computer does not power on.	AC power cord not connected. PSU switch is off. Loose cable connections. Faulty component (motherboard, CPU, etc.).	Ensure AC power cord is securely plugged into PSU and wall outlet. Flip PSU switch to "I" (on) position. Check all modular cable connections (24-pin ATX, EPS, PCIe, SATA). Test components individually if possible.
System powers on but shuts down immediately.	Overload or short circuit. Overheating. Faulty component.	Verify total power draw does not exceed 750W. Check for loose screws or metal objects causing shorts. Ensure proper ventilation and clean dust from PSU fan. Disconnect non-essential components to isolate the issue.
Unusual noise from PSU.	Dust accumulation in fan. Fan bearing issue.	Clean fan and vents with compressed air (power off and unplugged). If noise persists, contact Cooler Master support.
