Hello, I'm wanting to upgrade my system and not spend that much money so I wanted to upgrade from a
Gigabyte GTX 770 OC 2GB to 2 7870s probably also by Gigabyte once I purchase them.
The main question I'd like to know is will my PSU support them and is this a viable upgrade from my 770
Specs-
GTX 770 (Current GPU)
I7 3770K 4.2 GHZ
8GB vengeance Blue 1600 MHZ
Samsung 840 SSD 120GB
Seagate 1TB HDD
LQ310 liquid CPU cooling
Xonar DX sound card 7.1
Zalman Z11+ case
MSI Z77 G45 A MoBo
Cooler Master Extreme 2 Power Plus 725W(Liar Label Wattage)
Also I believe the power supply has 2 +12V Rails each supporting 28A So If I multiply that it's around 672W In total...
Thanks
