Graphics Card help

[Aac18]

Hi there, I recently purchased a system with a GTX260 862mb graphics card built in. Now my old system has a 8800GTX 768mb graphics card. However because the old system isn't in use anymore I was thinking of taking out this card and using it as a second graphics card (dedicated to PhysicX) for my new computer.

My problem is that I currently have a Corsair TX 650W Silent Power Supply. I'm no expert with regards to computers so I was wondering is there any way I can tell how much of this power supply is in use? and in turn from that work out if the power supply is suitable to handle a second graphics card.

Any help would be greatly appreciated, and if anyone has any tips for installing the second graphics card that would be great (I know that I can't run the two cards in SLI due to their different model type).

Edit: I use a Antec 300 Three Hundred Ultimate Gaming Case so there should be plenty of room in the case physically for the card so size isn't an issue.

Running a GTX 260 and an 8800GTX on a 650W, even a quality one like your Corsair, is going to be pushing it. You can et an estimate of your power usage here [http://extreme.outervision.com/psucalculator.jsp], though it shouldn't be too problematic if you install the second card and see if it leads to system instability (crashes, random reboots, etc.) I don't know how hard PhysX runs your second card; it might not operate anywhere close to full load.

I will say that if it were me, I wouldn't bother installing the second card-there are only a couple games that make use of PhysX beyond what a GTX260 can handle on its own.

Thanks for the information, I'll look into it. I was really only looking at Batman: AA for PhysicX because it makes such a massive difference to the games detail (and from the demo game play its a fantastic game that I'd love to enjoy to the maximum).
