Will a CM Silent 1000w be enough?

[Frraksurred]

I'm adding a 5870 XXX to the "Fire" system in my sig for Crossfire. I'm curious if also putting my old 9800GTX in for PhysX would over extend this PSU or not?

I'm not OC'ing anything (apart from the card's factory OC) and I'm running a sound card, 2 opti drives, a SSD and a HDD. If my guess is correct, I'll just be squeezing in under the wire, but I figured I'd better ask anyway.

Thanks for your help.

Yes, 1000W is plenty for those components. You're not even close to the limit.
