Computer Mother Board Replace

[gcowett]

I have a 5 year old e Machine that the mother board went bad. I ordered a new board from from Geeks.com .
The one I order needs one 24 pin power and a 8 pin 12v power supply. Board is a EM945G Serial ATA.
Can anyone tell me where to get a power supply with a 24 pin and a 8 pin 12v setup for a mATX Case.
Thanks to all who may be able to help.

 i believe you can just get one at geeks. don't be confused by 20 + 4 pin as i believe it means it is compatible with the old 20 pin power + the 24 pin power connectors. just do a little research on model you want and i think you will find just what you need. any psu made in last few years have all the connections you need.
