Understanding PSU Protection Features
When a PSU's protection mechanisms are triggered, it means the unit has detected an anomaly (such as excessive current, abnormal voltage, or high temperature) and has shut down to prevent damage to itself or your PC components.
Common protection types include:
- OPP (Over Power Protection) / OCP (Over Current Protection): Triggered when system power draw exceeds the PSU's rated output. Results in instant shutdown or auto-restart.
- OVP (Over Voltage Protection): Shut down the PSU if output voltage exceeds safe limits to protect the motherboard and GPU.
- OTP (Over Temperature Protection): Shut down the system if internal PSU temperatures become too high.
- SCP (Short Circuit Protection): Immediately cuts power if a short circuit is detected (e.g., faulty wiring or component failure).
In short: These features ensure the PSU "chooses to stop running rather than risk burning out your computer."
