Hello,
My current system is:

Corsair Air540 with 3x Corsair AF140
Asus Maximus VII GENE
Intel i7-4790k @ 4.4ghz
Corsair H110 with 2x Noctua 14cm ppm 3000
Corsair AX760i
32gb (4 x 8gb) Corsair Dominator 2133mhz CL10
Asus GTX780TI-DC2OC-3GD5
Samsung 840 pro 256gb
WD 1TB blue
Asus ROG SWIFT PG278Q

Ever since i got my Rog Swift I have been thinking on upgrading my GPU in order to cope with the high demanding 1440p.

My question would be if my current power supply will be enough to handle an 2 x GTX970 upgrade?

What about 2 x GTX980?

Let me know your opinion guys :)
 
Solution
Yes, the new nvidia cards are very power efficient.
Use the tool I provided to get a clear estimate, you won't go above 600W peak with SLI GTX 980.
