New Build compatability

[pokeairguy]

Hi
I'm building my first desktop and I have the following spec:
Optical Drive GH24NS90
Case Zalman Z9 U3
CPU Intel i5 3570k
GPU XFX HD 7870 2GB
HDD Seagate 2TB Barracuda
Motherboard ASUS P8Z77-V
Power Corsair 750W CXM
RAM KHX1600C9D3P1K2
Windows Windows 7 HP 64 bit
Card Reader Xenta All in 1 Internal Card Reader

I plan to use it for gaming and some basic photo editing. My budget is £900 but don't want to use this all. I know the PSU may be overkill but I do plan on bridging a GPU in the future and possibly overclocking the processor. I am wanting to make sure its all compatible? Also would anyone recommend alternative components?

Thanks for any help!
David
