Excellent, that's exactly what I'm after, thank you. 9600GT added.
How much power do two 9800GX2s require? I'm having trouble finding the info.

I've added the single 9800GX2 with a recommendation of 580W & +12V@40A. With regards to the SLIZone recommendations, be aware that they only certify PSUs that pay the certification fee. While I can certainly see the value in such a list (as a lot of manufacturers will put exaggerated claims on a PSU label, and while those numbers may meet the requirements, the PSU may not be able to power the system), such a list is not exhaustive.

How about 2 9800GX2's in SLI?
I see a 850W PSU is in that list
http://www.zalman.co.kr/ENG/product/Product_Read.asp?idx=198
But that has a lot of Amperage on the 12v rails (six of them, with 18x4 and 22x2)
Can this keep up with 2 9800GX2
Silverstone 850W Strider

or
Gigabyte Odin 800W

The ST85F should handle two of those cards. I'll add a recommendation to the list when I have some more information about these cards, but it probably won't be much below 850W, particularly given that people using two of these cards usually have a lot of other power hungry hardware.

will a 800W Gigabyte Odin work with 2 9800GX2 in SLI + a new Quad core + a better mobo etc.
Cause i saw the 850W silverstone Strider in greece and it costs R1750 there and the Gigabyte Odin 800W costs R2000 here.
so will 50 watts make a differece in that setup?

I'd get something around 700W. Like the OCZ GameXStream.
According to ceewi1, 250W. Take a look at the first post. It falls under "Low-end/Integrated."

I know but just to be safe-er, I'd like to get a bigger one. After all, the PSU is the most important part of the comp, I don't think over-estimating on that one should be a big problem
Of course unless you buy a 1000W to power up a pair of 7600GS's for example

Thanks, tentative figures added for 4850 & 4870.
It can be done, but I'm not sure I'd want to be the person running that system after a year or two. That's pushing the HX520 a little
As mep916 said, that falls into the lowend category. 250-300W would be fine, assuming the rest of the system isn't at all power hungry (at that level, the effect of the video card on overall power consumption is not really all that significant).
