2 4890s in crossfire 700w enough?

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?

  2. Yea, my cooler master 700w also has 19 amps on each of the 12v rails. Any ideas, guys?

    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.
