I'm thinking on buying an EVGA 80plus gold, 650w power supply for my build, these are the specs (Nothing has overclock) :

-Intel 4690k (At 3.9GHz with TurboBoost)
-GTX 970 Msi 4G
-16GB Corsair Vengeance
-500GB Adata SSD
-1tb WD 5400rpm Red

I currently have a EVGA 750W 80 plus bronze PSU, but the problem is that is too long and it doesn't let the hard drive cage be inside the case (Corsair 380T)

And finally, I'm looking for a fully modular PSU.

Thanks in advance.
