I'm putting together my first homebuilt computer. had everything setup correctly (I think). Went to turn it on for the first time and the circuit breaker tripped.
I reset the breaker, only connected the minimum necessary to start. The 20+4 power and the 4+4 12v. Tried again, same result.
The only thing connected are the cpu w/fan and 4 ram. I have a video card in the slot, but disconnected the power. I also have the connections for the power/hdd light/led light connected.
What I do is plug in the psu, turn on the power switch on the psu and then when I press the power button on the front of the case, it trips right away. One time, it took about a second to trip. The CPU fan ran for about a second and then trip.
I don't think I'm overloading the circuit with normal use since I use the same plug for the vacuum cleaner and it doesn't trip.
One thing is the 12v connection has connections with the square ends and the rounded ends and it's impossible to get everything to line up with the power supply. The power supply connection consists of 2 - 4 pin connections side by side and they're right next to each other so there's no way to reverse them and the clips line up with the clips on the motherboard, so there's only one reasonable way to connect it, but the reasonable way results in squares in rounded holes and vice versa.
This is my system (from NewEgg)
2 x LOGISYS 120MM4LED CASE FAN CF120BL
1 x HD 750G|SAMG 7K 32M SATA2 HD753LJ
1 x PSU ROSEWILL|RG630-2 630W
2 x MEM 2Gx2|GSK F3-10600CL9D-4GBNT
1 x MB ASROCK|P55 PRO
1 x VGA XFX|HD-487A-ZWFC HD4870 1G
1 x DVD BURN SONY-NEC|AD-7241S-0B
I haven't had an opportunity to try another psu. I can probably do this today.
Anyone have any suggestions for me to troubleshoot?
Stand-offs are in. It seems to definatly be a bad PSU.
I'm asking for a refund from NewEgg for the Rosewill and will get the
OCZ ModXStream Pro OCZ700MXSP 700W ATX12V V2.2
The reviews are good. 10% give 1 star on NewEgg, but many of them are because the rebate didn't work. A 5-10% failure rate is about as good as one can expect from a PSU. Plus, if it fails, I can drive to MicroCenter as opposed to paying $12 to ship back to NewEgg in addition to a 15% restocking fee. I can live with having to pay to ship back since most vendors do this, but to charge a 15% fee to give them back a POS they sold me makes no sense.
