Answered! Thanks, all.
Hey guys, I'm thinking of putting an Asus GTX 760 DirectCU II into a build that already has an Antec VP-450.
Supposedly, the GTX 760 requires 30A on the 12V rails to run, and the VP 450 delivers 18A on each of the two +12V rails.
Question 1: Just based off the info above, would the PSU be able to run the GPU? I'm guessing yes because 30A< 2*18A, but I'm not sure if that's how PSUs work.
For the next part, the GPU requires an 8 pin PCIe power connector, and the PSU only has a 6 pin PCIe power connecter and a 4+4 pin ATX12V/EPS12V connector.
Question 2: Will I be able to plug the PSU into the GPU? I'm assuming the 8 pin PCIe connector should be 6+2, which means unfortunately the parts aren't compatible.
And if by some miracle, the answer is yes to the first two questions:
Question 3: Is a 450W PSU enough to run a GTX 760? Assuming that the other parts in the system are: CPU (65W), 2x4GB DDR4, HDD, 3 case fans. Answered: Seems like total power draw would be around 300W.
Thanks for any input. :)
