Corsair CX500
Preliminary Information
Release Year ~2013
Leak Risk Low
Mounting Technology Through Hole, SMD
Capacitor Types Aluminum Electrolytic, Ceramic
Destructive Entry No

The Corsair CX500 is one of the budget model PSU's. It's very similar to the CX450 and CX600 and its modular counterpart CX500M.


This PSU used CapXon brand capacitors, so they might fail quicker than usual.

Known Issues

Cause

After several years of use, the computer will sometimes not turn on. In-particular the the 'Power Good' signal will not work even though it's outputting all the voltage rails correctly.

Solution

  • Change/Modify a single resistor. This is not a capacitor issue
