Hi guys!

First of all, here's my build:
i5-4690
Corsair H80i GT
16GB RAM
MSI Z97 Gaming 3
Gigabyte Aorus GTX 1070 8G
SSD Sandisk 960GB Ultra II
SSD Kingston 120GB V300

My friend is recommending me to buy a 750W PSU, do i really need a 750W for this build?

If i really need 750W, should i buy a Corsair CS750M or a EVGA G3 750W

PS: The Aorus GTX 1070 is new on the build, i already have a PSU (Cooler Master G600 80+ Bronze), and he's telling me that the PSU is not going to handle the new VGA.

84W CPU + max 215W GPU. Mayb 60W for the balance of your components.

No, you do not need a 750W PSU (FWIW, the CS750 is poor).

The G600 is 'ok, but not the best. Where are you located? A quality ~500W PSU (SeaSonic G550, for example) shouldn't break the bank.

You should be able to get away with a 450w PSU minimum, although 500-650 gives some good breathing room.

Out of the two you mentioned, the EVGA SuperNOVA G3 is the better unit. Although Seasonic has some good units (like the G series) that are a bit cheaper but still of high quality. If you want Corsair, but need Gold level... look at the new (and brought back) TX series of PSUs if they are in your budget.
