Answer» Its a 30amp and i am in australia. there was definately no burning smell and it goes off as soon as i press the power button on the pcQuote from: Rapidlywild on February 13, 2011, 05:38:33 AM Its a 30amp and i am in australia. there was definately no burning smell and it goes off as soon as i press the power button on the pc Have you got a spare power cord? I guess you could try that, but I suspect the PSU. If you have more than 1 breaker, you could try plugging it into an outlet on another circuit e.g. upstairs. yes i tried 2 different cords, the BRAND new one and one i have been using on my monitors.Breakers do get faulty, sometimes they get a bit over sensitive. There are combined overcurrent/earth leakage breakers so it could be earth leakage and not overload that is tripping the breaker. Either one suggests the PSU. I guess it would be tricky to TAKE the computer to another house and see if it trips the breaker there as well. Might annoy the neighbours if it does. Out of interest... Post the full details written on the circuit breaker. Post the full details written on the PSU. The problem is in your computer not your house wiring. Do a full visual check of the build wiring. Check the back of the motherboard isn't shorting out to the case.Heyya Fed Wells I definately believe its the PSU. I was told to do a test as follows: "Disconnect the power supply from its source of power, and make sure no power supply leads are connected to anything. Take a sort piece of wire as shown in the attached pic to make a "jumper". Put one end of the "jumper" in the GREEN wire hole on the main power connector that connects to the motherboard and the other end of the "jumper" into any hole where a BLACK wire connects on the main power connector (there will be a BLACK wire hole right next to the GREEN wire hole) . Power on the power supply and it should start and run. If it starts and runs, on let it run for a few seconds then disconnect it from its source of power. If the power supply trips the household circuit breaker while the "jumper" is in place, the problem is an internal short in the power supply and it should be replaced with a new unit." I attempted this as the PSU did not do anything. So I believe the PSU is deadddddddd so ill be taking it back where I brought it and I am hoping that it has not damaged the motherboard and the CPU as its all new. I will be balling my eyes out if they have been damaged as I have saved up to buy them.But did it trip the circuit breaker when you carried out the test? You see, if the PSU was tripping the C/B then it should have tripped when you tested it. I'd dig a bit deeper before calling it the problem. Let us know how you get on, we do like feedback here.Heyya Fed, Good News, I brought a new power supply TODAY after taking my machine into a mates shop. The original (new) PSU was definately faulty as it triped his shop when he tested it lol. So now I have a Corsir 600W in there and its purring like a charm. Ill be making a visit back to the place I brought the original Cooler MASTER PSU from to demand a refund. LUCKILY there was no damage to the motherboard or CPU. I would like to thank EVEYONE on here who assisted me on this frustrating issue. All your help is greatly appreciated.A great result & feedback, Salmon Trout nailed it 1st up.
