Hello guys,
I am really confused on my first gaming computer build, I have NEX650G PSU 80 PLUS GOLD. I have connected to it two PCI-E (one 6pin) and (one 6+2pin) from the psu to the EVGA GeForce GTX 770 Superclocked w/ EVGA ACX Cooler GPU, when check the manual of the PSU it says +12 is MAX output is 20A. The question is it enough for the GPU. (Minimum recommended power supply with +12 Volt current rating of 42 Amps.) This retrieved from GPU website.
 


Yes you have enough for 770 SLI, if you desire to do that. I would stick with a single GPU, but if you need to add more power for higher resolutions, than the 770 SLI option can work. Personally I would opt for the GTX 780, if you haven't already purchased the GPU yet. Then in a year or two you can upgrade to the latest single GPU option available at the time,
 


Depending on your other parts and if your OC'ing, Tom's rated the GTX 770 at 193-246w max, depending on what your doing. So it would be pushing it, but since the PSU is Gold Certified it will run a bit more efficient than most PSU's. Like I stated before, I would stick with single GPU options, but that is up to the OP.
