I have the asrock fm2a88m pro 3 + (mobo) and my PSU has 2 cables labeled CPU and my mobo has 1 slot that seems to fit 1 of the 2 cables
 
Solution
It depends on how what the mb is rated to handle for cpu wattage, so a board for example with 125w cpu requires an 8 pin (4+4) connector. So you're just fine with the 4 pin.
