Source overvoltage

What is PSU-OVERVOLTAGE?

The PSU-OVERVOLTAGE error is categorized as a critical-severity power supply unit (PSU) issue that can significantly impact your PC's stability. The power supply supplies a higher voltage than specified. Risk of component damage. When experiencing the Source overvoltage fault, users often report sudden system crashes, unresponsive behavior, or a blue screen of death (BSOD). In most diagnostic scenarios, this problem is directly triggered by underlying hardware or software complications such as faulty psu, failure of ovp protection and poor quality source. To permanently resolve the PSU-OVERVOLTAGE issue and prevent further system degradation, it is highly recommended to follow our step-by-step troubleshooting guide below, ensuring your power supply unit (PSU) components are functioning correctly.

Common Causes

• Faulty PSU
• Failure of OVP protection
• Poor quality source
