I'm in process of building my first rig and have everything assembled but can't get the PSU to supply power. I tried the paper-clip test and everything seemed to be working fine, but when I plug it in to the motherboard nothing happens. At this point, I'm kind of freaking out because I fear that the motherboard is broken. What I also considered might be causing it is, I bought all the parts from hardwareversand.de so, the plug for the power supply was one with 2 circular pins which wont work over here (Ireland). However, I've bought another cable which I was told would work, but it hasn't seemed to make a difference.
Any help, would be enormously appreciated!

Make sure that the power supply is rated for, and the selector switch (if there is one) is set to the wattage supplied from the grid (the wattage that comes out of your wall) I'm not sure if Ireland is different from USA. I know most Euro and Middle East countries for that matter have a different wattage coming out of the wall than we do here. Double check your connections to the MOBO (one big connector on the right side of your board, one smaller one near the CPU). Also be 100% sure that the cable that you replaced the original with carries enough power. That's all I can really think of. I hope it helps.
Thanks for correcting me on Volts vs Watts. It's too early in the morning for my brain to be fully functional. Need more coffee.
I've had very few issues with a PSU. The only thing I could think of is that either there's a bad connection, or the board is not getting enough power to it. Often things that make sense in my head are gibberish when I try to explain it to others.
