• OCP (Overcurrent Protection): Protects against current exceeding specified limits.
• OTP (Over Temperature Protection): Shuts down the PSU if the temperature becomes too high.
• UVP (Undervoltage Protection): Shuts down the PSU if voltage falls below tolerance on single lines.

Troubleshooting

If your system does not start after installing the PSU:

• Check that the power cord is properly connected to the wall socket and the PSU.
