  1. You might be pushing the psu's limits with a sli config. What card are you going to use?
    Usually a 750 watt psu is needed for that.

    Either way keep the antec psu if its not too old since its a decent psu already.
  2. Best answer
    I would use the antec personally. Mainly because manufacturers like to overshoot their PSU ratings and that 650 is rated for 456w on the 12v rail and thats... a little low. Plus I haven't heard to many glowing recommendations for ULTRA.

    I was thinking that too, but it has amazing reviews...

    Also dont most graphics cards take 2 pci-e power cables? Both psu only has a total of 2 so you are going to need some molex adapters as well
  4. Thanks for the input guys. I haven't bought a new card for a couple years but did some research. Looks like most of the high end cards require 2 6 pin connectors. I'm going to be using 2 XFX 9800 GT's for a couple weeks until I decide what video card route I want to go. I think i'll probably go with the Antec PSU then, and since the ULTRA is still sealed in plastic I may just sell it.

    Again thanks for the help and the heads up on the power requirements of new cards.
