Final Build- Just want to check if this is Okay

Solution
Every thing is compatible just get a good quality 500 - 550watt PSU (seasonic , xfx, antec HCG etc) instead of cheap 800 watt PSU.
If you are going for a non OC processor then get a h97 or h87 board .

You can have a look at this build.
The 750 watt PSU is just in case if you want to add another card in future but if you are not planning for SLI then a good quality 500 - 550 watt PSU would be enough.

Solution


No corsair VS,CX,CS and RM series of PSU are poor quality PSU of tier 3 so if you insist on going with a cosair PSU then go for HX, TX, AX PSU but they are costly.

So the best is if you go for EVGA G2 its a tier one PSU and best bang for buck PSU of 750 watt.
