    Default Power Good 50ms, can this be repaired?

    I have a Corsair RM650 and one of those cheap $15 no name PSU testers off Amazon. The RM650 shows good on all areas except PG 50ms. Back story, I have been having stability issues with the PC it was installed in until I tried a different PSU I have laying around and the PC stability problem disappeared with the test PSU. That is when I tested the RM650 with the tester and found the PG 50ms. My question is is this something I can fix or is the PSU destined for the scrap bin since it is out of warranty.

    The power good signal being 50ms will not cause instability. If the power good signal was not correct, it would prevent the PC from posting. Once the PC posts, the power good signal is a constant signal. The 50ms you're seeing (if it's correct), is how long it takes for the PG signal to become "live".

    As for the PSU being out of warranty: It's 7 years old?

    Sometimes the PC would POST and sometimes it would not you never knew what it would do. Once running it might run for weeks then randomly power off for no reason while other PC in the house would continue to run. Installing a new PSU cured all that. I guess I don't fully understand what the function of the PG signal is and how it effects the PC. I don't actually know how old the PSU is as it was in a PC that I acquired in an estate sale and I just assumed there is no warranty. I also assume the PG issue is not something that I can fix? I just figured the PSU was a write off.

    On a side note, according to the tester, I can power it on and get the 50ms reading, the next time I power it on I might get 70ms and back and forth it reads each time randomly but never more than 70ms.

    DOH!

    OP: If you feel comfortable opening the PSU up, do so and look for any swollen caps on the secondary side.

    I don't think so. Probably closer to 1.5 to 2 years but I don't have a purchase date since I acquired it already installed in a PC.

    A PC built by a professional system builder? Then the system receipt should be fine.

    Surprised the system builder doesn't have at least a 2 year warranty on their build.

    This is sound advice and worth checking. I'd not worry about the 50ms
