Activation of overcurrent protection (OCP)

What is OCP-TRIGGERED?

OCP-TRIGGERED is a critical-severity power supply unit (PSU) problem. The source detected a dangerously high current draw on some of the lines (typically 12V) and immediately shut down the computer just to be safe. Use the steps below to track down and fix the cause.

Common Causes

• High peak consumption (transient spikes) of powerful graphics cards (e.g. RTX 3080/4090)
• Short circuit in some power cable or component
• Defective or weak source

Step-by-Step Fix Guide

• 1
  Upgrade to a higher quality power supply (ATX 3.0 compatible)

  Upgrade to a higher quality power supply (ATX 3.0 compatible) tends to be the quickest win here, addressing the most typical cause of OCP-TRIGGERED.

• 2
  Test cables for damage

  A second occurrence often means a less common psu instability cause is at play, which later steps address.

• 3
  Try undervolting the graphics card

  If earlier steps didn't help, "Try undervolting the graphics card" directly addresses high peak consumption (transient spikes) of powerful graphics cards (e.g. RTX 3080/4090).
