Unhappy Help with building a new computer.

Hey guys,

I've just started building a new computer, got it ready and good to go but when I pressed the power switch, nothing happens.

I'm using;
Processor - AMD FX-4300 AM3
Ram - 2x 4GB Corsair
Motherboard - GIGABYTE GA-78LMT-USB3
Case - CiT Vantage Type-R Gaming Case with HD Audio, 4 Fans.
PSU - ACE A-750BR

I've been to all sorts of forums just browsing to try and find out what the problem is but they all seem to be saying the same thing about just making the PSU connectors are in the right place, which I'm fairly certain they are. I've followed the manual for the motherboard and everything is in place according to that, although I'm not using the IDE because I don't need it.

Although, the motherboard has no LED light on it from what I can see, but when plugging the kettle lead into the back of the PC I can hear it spark, so there is power going into it. I'm lost for ideas, any help would be greatly appreciated.

If anyone needs any more information please let me know, thank you

Aside from that PSU being absolutely horrible, it could be bad, the motherboard might be shorted to the case, or you might have the front panel connections plugged in wrong.

Easiest way to find out is take the motherboard out of the case and place it on the motherboard box. Then, plug the PSU in and only it. Take a screw driver (or if the power button can be removed do it) and short the 2 pins for the power button on the motherboard. If it turns on your case was shorting out causing it not to turn on. If it doesn't, the PSU or motherboard could be bad.

Another update, right, I've got the computer turning on through trial and error. The computer wouldn't turn on if the SYS_FAN cable was plugged into the mother board, but I've still got the side fans and back fan plugged into the cable that should be going to the motherboard and all the fans are working. If all the fans are working, does it matter there's no cable going into SYS_FAN?

No, you don't even have to have any fans plugged into the motherboard.
