I recently bought a GTX 780 Ti. I noticed that it requires +42A on the +12V rail. The PSU I'm using has four +12V rails each rated at 40A and I'm not sure if this meets the requirement of 42A. Right now I have 2 separate PCI-E cables connected to the card and it seems to be running fine, significantly faster than my previous card (GTX 670). Crysis 3 is the only game that doesn't seem to be running as expected. Can someone confirm if this PSU is suitable for running the card at its full potential? I'm also planning on upgrading my PSU so I can add another 780 Ti in the future. Any suggestions to what PSU I should get would be welcome. Thanks!
