  1. Hi,
    I bought a PSU from PC world yesterday- I put a power cable in it to see if it fitted, but forgot it was plugged in a the end. There was an almighty "BANG" and the fuse tripped and all the appliances went out. Is my PSU toast?
    Thanks.

    Your lucky your not toast !

    Your motherboard could even be toast.

    I`m guessing it`ll just be the PSU.

    Does it look burnt ? Replace the fuse,

    and try it with the correct voltage on the correct wires.

    No, nothing was plugged in except the power lead. I just forgot it was plugged in the wall as I was seeing if it fitted. Do you it was DOA? I only bought it yesterday.

    Oh,I see.I just assumed you were fiddling with the internals.

    Deads PSUs normally just don`t do anything at all.

    If your in the UK,have you checked that there isn`t a voltage switch

    that was wrongly set on 120 V instead of 240 ?

    I would say try it again,after you have secured the plug,but that might

    bring down all your appliances again. :)

    It has a switch on the back saying "120" on it. No Idea what it means.

    Well,if your in the UK with 240 V mains supply the PSU voltage

    switch,should be set to 240 V.

    Otherwise, BANG !!

    Was the psu plugged into the motherboard, and any other hardware when it went bang?

    No, it was just the psu on its own. Should I correct the voltage and try again? The fuse tripping could have saved it. Thanks.

    That's good news. At least no other components were taken with it.

    You can test to see if the psu is still working here.

    Regards Jase :)

    Personally, i would just get a new psu and save any danger.

    But you can still test it, using the thread from the link above.

    BUT DO SO AT YOUR OWN RISK!

    I don't want you electrocuting your self.

    No, if the psu smells funny, then it`s probably blown and could cause untold damage to your system, if it hasn`t already.

    Far better to get a new psu in my opinion.

    By default it should have been set to 240 volts seeing as it was sold in the UK. Take it back and give them hell over it.

    i agree with rik, i was about to post the same thing but he beat me to it ;)

    if it's gone bang and smells funny then i wouldn't put it in your pc, it may have the potential to irreversibly damage your whole system

    Ok, Thanks for all the replies. The PSU is definitely toast-It still smells like gunpowder in my room even now!:dead: Parts inside it seem to be knackered, I can see through the grill. To be honest, if I try it again it will probably explode or something, and even if it did seem to work I would not use it on my mobo when it comes anyway, it could have been messed up in a different way like current coming out wrong.

    LOL, its toast. Should have known right then. That 120 is the Volts it was set to, since you guys use 240 over there, its fried.
