I have 500 watt PS maxed out and I just bought a corsair a AX750 gold V2.3 and now I find that my MB is a ATX 24-pin Power Connector: ATX1. In the instructions for the AX750 they warn you about the P4 connector and to use 1 4 pin ( it comes apart 2 4 pin connectors) of the 8 pin EPS12V in place of the P4. What do I use to power the P1 12v connector to the CPU. I have a second EPS12V cable can I use one of it's 4 pin connectors to power the CPU.

MB PDF P55-CD53/MS-7586
ATX 24-pin Power Connector: ATX1
This connector allows you to connect an ATX 24-pin power supply. To connect the ATX
24-pin power supply, make sure the plug of the power supply is inserted in the proper
orientation and the pins are aligned. Then push down the power supply firmly into the
connector.
You may use the 20-pin ATX power supply as you like. If you’d like to use the 20-pin
ATX power supply, please plug your power supply along with pin 1 & pin 13.

Don't let the PSU and motherboard manuals descriptions confuse you here. Your motherboard has one 4 pin ATX (EPS12v) and one 24 pin ATX main power header. Those are the only things to connect to the motherboard from the power supply. With those two connections, your motherboard should be good to go.
Note: if there is a motherboard version number, I may have referenced the wrong board but the same applies, two power connections to mobo only
