Asrock Z77 Extreme4 LGA 1155 Z77 ATX Intel Motherboard

SDSSDP-128G-G25 128GB SATA 6.0Gb/s 2.5" Internal Solid State Drive

Is this enough to power the box?
CX Series CX750M 750 Watt ATX Modular Power Supply

Or would I need a higher wattage PS?

Thanks for any advice and recommendations

Your graphics card requires one 6-pin PCIe connector. Any good quality 400 watt unit has one. The other components are of no concern since they're pretty low power. You'll be using around 200 watts while gaming with both the CPU and GPU moderately overclocked. But for future proofing purposes, you'll probably want native support for a graphics card that requires two connectors.

Corsair CX500 $50 ($30 AR) @ Newegg - 80+ Bronze efficient, 3 year warranty, 2x(6+2)-pin PCIe
Rosewill Capstone 450W $64 @ Newegg - 80+ Gold, 5y, 2x(6+2)-pin PCIe

If you want support for dual graphics cards (which your board supports), a 650W+ unit with four PCIe connectors is recommended.

XFX 650W $70 ($60 AR) @ NCIX - 80+ Bronze, 5y, 2x6-pin + 2x(6+2)-pin PCIe, not modular
Rosewill Capstone 650-M $100 ($80 AR) @ Newegg - 80+ Gold, 5y, 4x(6+2)-pin PCIe, modular
