I just recently purchased an epox motherboard for my first build. My old power supply has only 20 pins, while the connecter in my motherboard has 24 pins. I got a response from epox that said to just use my 20 pin power supply, just make sure the pins line up. This would leave four holes/pins empty. This hardly seems right. I though I'd ask you guys first. Thank you.

Hmmm...sounds interessting :|

I would buy one of these tho: http://www.directron.com/20to24pin6in.html

I decided to give this a try and it worked, just to let you know.

Nice one browning, and just for future reference you can go the other way round as well e.g using a 24 pin PSU on a 20 pin board.
You just need to purchase an adapter.
