Last week lightning stroke 20m from my home and one of the broken thinks is my pc.

This is what I have at the moment:

  • Fractal Design Define R4 Pearl Black;
    MAXIMUS VI HERO;
    intel i5 4670k;
    N770 TF 2GD5/OC (gtx 770);
    8gb ram;
    1tb WD black;
    1 DVD drive;
    Corsair CX750M;

So I know that my motherboard and CPU are broken.
I wonder if replacing the motherboard and the cpu with a i74770K and add another gtx770 requires a more powerfull psu like the Corsair RM850?

If anyone could help me or has some advise, I would like to hear it.

There's a surprisingly little difference between the 4770K and 4670K when it comes to gaming. Upgrading is up to you of course, but I wouldn't buy it unless you're video editing or something similar.

For two GTX 770s and an overclocked i5/i7, a good 750W is sufficient. However, the CX750 isn't a good PSU. For only a bit more get this XFX 750W. It's modular and much more reliable and efficient than the CX750.
