If your system is having issues turning on, you can check if your power supply unit (PSU) is functioning properly by performing a test.
You will need a paper clip or a PSU jumper to perform this test.
IMPORTANT: Make sure that you jump the correct pins when testing your PSU. Jumping the incorrect pins may result in injury and damages to the PSU. Use the image below to see what pins you need to jump.
To test your PSU:
To test your PSU with a multimeter, use the following chart and continue from the previous steps:
Another way to test your PSU is to use a power supply tester, like the one pictured (others can be used, this is just the most common). To use one, follow the steps below:
If any of the voltage ranges are outside of the parameters, submit a ticket through our site and provide photos of this to your support agent.
*When -12V was made “optional” in the ATX 3.0 and newer spec, Corsair decided to remove the -12V. With these testers, instead of showing ZERO for the -12V, they’ll usually show around -13+, which is a false reading.
Also, the PG signal requirements have been reduced from <500ms and <500ms for T1 and T3 respectively, to <200ms and <100ms since the latest ATX12V revision. So most of these testers will error on the “PG” portion with newer PSUs that follow the newer spec.
