I purhased a DFI nF4 Ultra infinitiy MOBO and the Trio case made by sunbeamtech.com. I noticed that the ATX power on the MOBO is 12 pin while the connector that came with the case is 10 pin. Did I buy the wrong case? Can I fix this somehow? Thank you.

you can buy a 20-pin to 24-pin adapter, but since you invested in such a good board, I suggest you invest in a decent PSU to go with it. Get a true 24-pin PSU that's based on the new ATX12V 2.0 standard This space for rent

You description doesn't make much sence. The only 12 pin power supplies I have seen as AT power supplies. They came in two pices - 6 connectors on each, most of which where black for earth. You would have to search hard and long to find one now. ATX power supplies have 20 pins with the more modern ones having 24 pins. I know of no power supply that has 10 pins for the motherboard connector. Your DFI nF4 Ultra is an ATX board and the power connector is the clear plastic connector next to the floppy disk connector. See here for description. This shows the extra four pin power connector that you may need for P4 CPU's and some high power video cards. Whatever you are looking at with 10 pins, its not the power connector. Stuart

I meant the board has 24 pins, whereas the power connector has 20.

In that case post #1 from Jam applies. AS Jam suggests, a 20 to 24 pin adaptor may leave you underpowered. Stuart
