    Default PSU Failing?

    Recently I lost my TX650 V1, which lasted about 5/6 years.

    I have the habit of unplugging the PSU from the wall everytime I go to work or leave. For the last ~ 6 months of life of that PSU, everytime I plugged it in the wall it would make a *pop* sound. Eventually it failed (minor explosion when I tried to boot.). So I bought a RM650x. But everytime I plug it in the wall it makes a *click* (almost unnoticeable) noise, not *pop*. Am I being paranoid or there might be something wrong with the outlet (no ground). Any ideas on what I could do to prevent any kind of damage or find out the problem?

    Also, the RM650x is making a coil whine noise under load, But I don't think it's related.

    EDIT: I've been using a MOV based surge protector between the outlet and the PSU, but stopped since I got the RM650x

    Are you sure it's coming from the psu, and not the wall outlet? It may spark when you plug it in, especially if you constantly plug and unplug it from the wall.

    Because when you plug in a psu, you're charging up the primary cap.

    Do you have a problem with your electrical system since you unplug your computer all the time? Personally I leave my computers plugged in all the time, but the power grid here is very stable and the power is clean.

    The pop sound from the TX650 was 100% from the PSU. The click from the RM650x I'm 80% positive, I will plug it and turn the switch on trying to listen closely next time and see if I'm 100%. But I guarantee it's not from the wall. I know what you mean from the wall spark, and it's not that. The RM650x makes a noise which doesn't seem "electrical".

    No problems, not that the power grid here is good. I just do it because we have lots of thunder storms and it gives me a peace of mind.

    Could be a mechanical click then.

    You may have the rarest rm650x of all: One with a relay!

    Yeah, my first thought was a relay, but I searched and found out there is no relay. Should I keep observing or RMA it?

    Does it work right now?

    If yes, don't bother. if it dies down the road, well you still got 9 years and n number of days remaining...
    Do you have no earth for your psu??? are you running your psu on a 2pin power cord?


    If no, rma.

    3 pin, but I checked with a multimeter and there is no actual earth. I live in this house for 20+ years and have not had any problems. Think this could be an issue for the equipment?

    Wait, what? How did you check?

    Honestly, if there is no earth but your house has 3 pins (meaning that the 3rd earth pin just goes to nowhere), get it sorted out asap. That's a safety hazard, it's not just your pc that can electrocute you, it's a lot of things (Washing machine etc)
