My video card decided to leave me yesterday, and well I need to find a new video card.
I was using an old 8800 gts 640mb, and it seemed to work just fine. I've been looking at getting myself a 4890 Ati Card to hold me off until I can afford a full system upgrade. My only concern is whether my existing power supply will be able to support the card.

Linky Power Supply

I've never had to bother figuring out rail capacities and all that good stuff, I've always had just enough money for middle ranged rigs, and computers used to be easier to put together cause well you could basically slap anything together. At least thats how I remember it... anyways long story short, I need help from someone that knows more about Power Supplies.

Oh and I've tried reading up on it myself, and I'm going to assume the rails aren't getting enough amps. But again I'm driving blind at this point so I thought I would ask someone else.

Should work. An 8800GTS needs about 9 amps. A 4890 needs 12 - 15 amps at full 3D load. Figure 10 amps for an OC'd quad core (high estimate) and about 4 amps for one HD and one optical and a couple of fans.

You won't have a lot in reserve, but you should be OK.
