May 9, 2014 - Ive done a whole lot of tests and while the tests passed, i still had issues with games. So after updating all my drivers + BIOS, after checking Temp under load, after trying different drivers, after trying tweaking my GPU, still got same issue. So now i took out the GPU, and connected my monitor to my iGP, and behold! all games are stable! So now i want to check if its my GPU or PSU. I downloaded the OCCT program, and went to "PSU Test", turned it on, and it appears as if nothing is happening...

However, when it arrived, the connector physically does not fit into the PSU.

How to perform stress tests with OCCT step by step
May 1, 2026 - That's why many advanced guides recommend following a complete testing protocol with HWiNFO for PSU diagnostics, as it offers much more comprehensive logs that you can then review at your leisure. Even so, the OCCT Power test remains a quick and effective way to detect clearly insufficient or defective sources that can't keep up when the whole system gets its act together. In addition to launching its own tests, OCCT has a very useful mode called Monitoring only, in which the program is limited to displaying and recording the behavior of sensors in real time while you run other applications: games, external benchmarks, rendering, etc.

Hi all,

I am trying to lock in my settings and stabilize my first ever overclock and have run into an issue with OCCT returning errors on a power supply test. When using OCCT 5.0.1 power supply test (2019) it returns 63 errors, but I am unsure where to start with trying to resolve them. When I run the 2012 version I do not get any errors. I have attached the results of both below, and can see there is a difference in the power graphs. Am I missing a setting somewhere where OCCT gives me more information on the errors discovered or a more detailed report? This is my first time using OCCT

Hello,

I've been having issues with my PC resetting while playing some games (Spellbreak, Rust) or streaming (HBOmax, Netflix). It does not crash during League of Legends or while watching YouTube). Some people have suggested a power supply issue (though I have a 700 w PSU). I ran the power test on OCCT. I'm not sure what it did but from looking at the temps/power/etc. it seems like it puts a lot more stress on the hardware than those games would. After the hour test, my computer never crashed and the test found no errors.

Would this rule out a power supply issue and probably an overheating issue?
