Hello guys. I'm building a computer. here is the specs
CPU....................Intel i5-7600k
Motherboard.......Asus Prime Z270-A
Ram....................Corsair Vengeanse LED 16gb(2x8gb) 3000MHz
GPU....................Asus Geforce Dual GTX 1050(in future i'm planning to upgrade it to Dual GTX1070)
and 1x2TB HDD, 5 Case fans.

I have 2 options, EVGA 550w G2 or EVGA 650w G2. which one should i choose?

if you want to sli gtx1070

650w----700w

and nice choice with the g2

The EVGA 550W G2 is more than enough and is a good choice for your current rig (with the intention of upgrading to the Asus Dual GTX 1070 or even a GTX 1080).

The 650W version is good if 1) the price difference is soo close to the 550W (e.g., less than $10 difference) or 2) if you are thinking of upgrading to a GTX 1080 Ti.

Thank you for your information.
