PSU Blown Up

airbusA346 · 5 Apr 2015 at 13:23

So this morning I turned on my computer and it tripped all the upstairs sockets in the house.

So just to make sure it was the computer and not the extension lead. I plugged the tower in (direct to the socket, not via an extension lead) and soon as the switch on the socket was turn on, the sockets tripped again. I didn't even turn the computer on.

I tried the monitor cable, and it didn't trip, and a different PSU cable and it didn't trip. But with one of the working cables, the computer won't power on when pressing the button, so to me it appears the PSU has given up.

Either the cable has become dodgy over night or the PSU has taken the cable with it.

Hopefully it hasn't blown anything else!!!!

Any recommendations for a 800W module PSU? (Not too expensive)?

Thanks.

There was also some electrical burning smell from the PSU area.

As little as possible really.

ASUS Sabbertooth 990FX
AMD FX-8120 (not OC'd)
8GB RAM
Nvidia graphics card, but can't remember numbers (I know it requires 2 PSU connections)

The power button on the front of the case has been temperamental recently (taking a couple of presses to make it work).

Could this have potentially caused the PSU to blow up?

With your setup a 550w will be fine.

The power button on the case would not course a issue as the just makes a latched contact.

So there is no benefit running a 800w.(the blown PSU is 800w)? Doubt the computer will be upgraded anymore than it already is?

Is there a chance other things could have been damaged (MB etc)?

If the Power supply is a quality unit then it should have not taken anything with it.

But you could do the Paper clip test with the PSU removed from the case and plugged into a different socket with a known working cable.

There is no real benifit in running a 800w PSU, as your system would only pull around 350w from the mains.

Could you recommend a 550 or 600w module PSU?

Thanks

It is a Tagan BZ PSU.

Just done the paper clip test with a fan attached and it does nothing. So it would appear to be 100% dead.
