Compatibility Check?

[DECL4N]

CPU - Intel i5 2500k
MOBO - ASRock Z77 Extreme4
GPU - Sapphire RAdeon HD 6870
RAM - Corsair Vengance 8gb 1600mhz
CASE - NZXT Phantom
PSU - XFX 850w 80+
DRIVE - Asus DRW-24B5ST 24x
HDD - 1TB Seagate

Are these parts compatible?

Yep, its all good. Just some general comments on the build.

Overkill power supply. Get a 600W for single GPU, 750W for dual.
Sandy Bridge and Z77 are compatible, but not optimized for each other. Get either 3570k or a Z68 board (preferably the 3570k).

corsair ram is a no no if you plan to install a heatsink. get gskill ripjaws or mushkin blackline ram instead.

also, id get a p8z77-v LK board instead since asrock from what i heard was cheaping out on power delivery caps

Already purchased the 2500k just down to personal opinion and what 750w power supply would you recommend modular if possible for £85 or lower?

Also would a z77 board lower my performance compared to a z68?

Z77 boards are optimized for Ivy Bridge. Since you´ve got the 2500K, then get yourself a Z68 board.

the xfx xxx 750w is around 96 pounds but it is more efficent and quieter than the standard 80+bronze.

theres virtually no diference between the z68 and z77 chipsets other than the z68 is a bit older. either one works and is just as good. id go with z77 as the manufacturers tend to add more new features that the last generation didnt have
