It will work:
1 x 24-pin EATX Power connector(s)
1 x 8-pin ATX 12V Power connector(s)
1 x M/B 20+4 PIN = 24-pin
1 x CPU 4+4 PIN = 8-pinhttp://www.raidmax.com/psu/rx_700ac.html
The 20+4 can be connected together to one 24-pin board connector, or separately, for some boards that have a 20-pin connector. The same for 4+4.
