I bought of these from scan a while ago (mine has a dedicated 4 molex lead coloured blue for the gfx card)

I'm upgrading to a Opty 146, DFI LP UT SLI-D (maybe DR) and a 7800gt. I presume all I will need is a "2x molex to 6 pin PCI-e adapter" for the gfx card.
If I upgrade to SLI in the future does anyone think I'll have any issues with this supply? It runs 28A on the 12v rail so I'm unsure if I will be maxing this out with 2x 7800gt's.
