GTX 770 SLI & 750 Physx with Antec HCP-850

[nerofive4]

I have a Antec HCP-850 and a GTX 770, I am debating on getting another for SLI as well as a 750 (possibly Ti) for physix, should this PSU be able to handle that or would I need to bump up to a higher capacity PSU? IF its close, would it just limit each cards performance, or is it more likely to crash my system?

850 is plenty for that.

I have a Corsair ax850...runs my 3570K (OC) and 2 780's SC just fine.

A pair of 770s on an overclocked system will pull around 575-600w at peak load, adding a 750 Ti will put you around 650w tops, 850 is plenty

That said, I don't think you would need to add a PhysX card to a 770 SLI system.

Yeah, I think you're good. If your PSU is not enough, you'll more than likely get crashing, rather than reduced performance. It's either enough power or its not.

Hi, Our PSU is okay for that
