I recently bought and built a new PC. My video card wasn't working properly so I called my card's tech support and they said that my current power supply didn't have high enough max amps on the twelve rail (it had 18 when they said it should be 20+) so I bought a new power supply.
The problem is, I installed it into the case and connected all the wires correctly, plugged it in and hit the on switch, but nothing came on. My motherboard light didn't come on so i know it wasn't recieving power. The power supply itself didn't even get power, as i couldn't hear it and the fans didn't come on. I was wondering what the problem was and how I could fix it
it's a Tagan TGA480-U01 and it's 480W. In case you're thinking I have it set to the wrong voltage, i've already checked, it's not at 230. thanks for the help.
