Hey guys, I have a 4890 xfx 4890 xxx edition. I was wondering whether if i added another 4890 my power supply would be strong enough. My power supply is the Cooler Master UCP 700W. What you guys think?

With a Cooler Master UCP 700? Dude you are fine, that thing can handle it. There are (4) 19A rails.

I'd look at selling the 4890 and getting a single 5870 though. That single card will best (2) 4890 in most cases.
