Higher power ripple (Ripple)

What is PSU-RIPPLE-NOISE?

The PSU-RIPPLE-NOISE error is categorized as a medium-severity power supply unit (PSU) issue that can significantly impact your PC's stability. The source produces higher than permitted supply voltage ripple. It causes instability or damage to the capacitors on the board. When experiencing the Higher power ripple (Ripple) 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 old capacitors in psu, cheap poor quality psu, congested resource and faulty pfc circuit. To permanently resolve the PSU-RIPPLE-NOISE 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

• Old capacitors in PSU
• Cheap poor quality PSU
• Congested resource
• Faulty PFC circuit

Step-by-Step Fix Guide

• 1
  Measure the Ripple on the 12V line with an oscilloscope

  Applying the first fix (Measure the Ripple on the 12V line with an oscilloscope) addresses the most common root cause of PSU-RIPPLE-NOISE and restores baseline functionality.

• 2
  Exchange for a quality PSU (Gold/Platinum tier)

  If the problem persists, proceeding with the remaining steps ensures all edge cases related to psu instability are covered.

• 3
  Check the capacitors on the motherboard
