Dell Optiplex 960 Blowing Breakers

[SirTankBall]

so i got this dell from one of my fathers friend for free. i got a PC from him before that works (witch i still use). but this one doesnt seem to work right, what will happen is if i plug it in in my room at will blow the breaker to my room and my fathers TV room, but if i plug it into the ketchen it wont blow that breaker but it will still blow the breaker to mine and my father TV room (the house is wired like shit). but it will stay powerd one, what will happen is both the CPUs cooler fans and the PSUs cooler fans will go to max and on the front on the PC i'll get a code of 3&4. from what i saw it was to do with ram. so then i then i thought i'll just jump the PSU, i did that and it poped the breaker so i'm think ok its the damn PSU. so then i try it on my batt back-up just the PSU, it didnt pop the breaker in the back-up unlike my houses breaker. but once i put the PSU back into the PC and pluged every thing back in, then it pop my back-up breaker. so now idk what it is. i'm still thinking its the PSU but IDK. i'll have a video up later showing what im talking about

Sounds like a faulty PSU. Might be either causing noise or earth leakage. Does your house use Arc Fault Circuit Inturrupter breakers or Ground Fault Circuit Inturrupter breakers? New homes in america commonly use the first one, and they trip if any arcs are detected, or in my case, any electrical noise at all (cheap power supplies, vacuum cleaners, etc)
 

Other countries may use housewide GFCI (commonly called RCDs in other countries) which trip if they detect earth leakage. In america these are built into outlets used in bathrooms and kitchens.

I desoldered the 24 pin header from a scrap motherboard and made an adapter, not sure where it is. But I just matched the colours. The pinout of the tiny connector is not the same as a standard one.

 

Here is a commercially availible adapter: http://www.ebay.com/itm/222442015254

 

I would solder the wires to the original PSU if I were you. Not going to make good contact just shoving them into the header

i'll try out the adapter. i dont just myself to mod a PSU that way
