Hi.

So anyway, I'm building my own pc from scratch, right? I have the mainboard, the CPU and heatsink, and the power supply installed, and I do my first boot test, to make sure the heatsink fan is running. The LED light on the mainboard comes on, but alas, nothing else. I quickly shut it off to avoid frying my CPU, and check my wiring. Everything appears to be okay. After several instances like this, I give up, and take it to the local PC guys. They plug it into their workstation with their own power cord, and it works completely on the first try, making me look like an idiot in the process. So I take it back home, plug it in again... and it doesn't work! I tried every outlet in the house, and I tested it with the power cable from my mom's PC as well. Nothing works! I don't know that much about household wattage. The Power Supply I'm using for my PC is 450W. Is that too powerful for your average AC outlet, or is it that the two power cables I've used simply not compatible with the power supply?
