PC tripping circuit breaker, suspect dead PSU

[Giganthrax]

So today, after a year of working just fine while plugged in this particular wall socket, my PC abruptly shut off while gaming.

 

Turned out the circuit breaker had tripped. I tried tripping it back on, but it kept going back down.

 

- I tried two different PSU power cables, but it didn't help.

- I tried different extension cable, didn't help. 

- I tried plugging the PSU power cable into a different socket, and that socket's circuit breaker tripped as well.

- Finally, I unplugged the PSU power cable out of the wall completely and left just the monitor and the speaker plugged in - this didn't trip the circuit breaker.

- Even after I added the vacuum cleaner to the monitor/speaker mix, everything worked fine. 

 

So, is there anything I haven't tried, or should I go shopping for a new PSU? I sadly don't have another PSU to test with.

Usually your circuit breaker tripping is a pretty good sign that your PSU has bought the farm.

I'd start hoping that the PSU didn't take the rest of your PC with it.

What PSU do you have btw?

That's the weird part. I have some 700W Black Pearl power supply that's apparently a test model power supply by cooler master that a friend who built my computer probably got for me in some sketchy way (I live in Serbia, this kinda hardware makes its way here). 

 

It's served me well for 5 years now, and what I think screwed it up is a huge power outage my neighborhood had a few days ago. 

 

Guess I'll go shopping and hope for the best.

So it's the good news. I bought a Seasonic M12II PSU (my first modular PSU <3) and it seems the rest of my components are working fine (I guess I'll know for sure after I've been using them for a few days). It has a nice 5 year warranty, so that's cool too.

 

All is well that ends well, I guess.
