It would be pushing it. 850w is better. And like you said the 570 is overkill for PhysX (Seeing as PhysX cards aren't really needed anymore)

770 takes 42A and 600w for it and the pc, 570 35A and 550W. So that's 77A and 600 + 550 - 300(for rest of system) = 850W, 77A

You won't get a 77A psu of 850W, You need to go to 900W eg Antec HCG 900

Guru3d would say that you would be fine with a 750 watt PSU, as long as you don't do a lot of overclocking.


Here is Guru3D's power supply recommendation:

GeForce GTX 770 - On your average system the card requires you to have a 550 Watt power supply unit.
GeForce GTX 770 2x SLI - On your average system the cards require you to have a 700~800 Watt power supply unit as minimum.
GeForce GTX 770 3x SLI - On your average system the cards require you to have a 1000~1200 Watt power supply unit as minimum.
Though we do have some reserves calculated into our recommendation remember this; if you are going to overclock the GPUs or processor, then we do advise you purchase something with some more stamina. The minute you touch voltages on the CPU or GPUs, the power draw can rise real fast and extensively. http://www.guru3d.com/articles_pages/geforce_gtx_770_sl...


GeForce GTX 570 in 2-way SLI
A second card requires you to add another ~225 Watts. You need a 750+ Watt power supply unit if you use it in a high-end system (800+ to a KiloWatt is recommended if you plan on any overclocking).
