Can an Ultra X-Finity 600-watt power two ultimate 6670's?

hi im wondering if this
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2132071&CatId=1483

can power two of these
http://www.newegg.com/Product/Product.aspx?Item=N82E16814102950&Tpk=6670%20ultimate

im also running an a8-3850 but in the near future plan to overclock it to around what these guys did
http://www.overclockers.com/overclocking-amds-llano-apu/

and on there it says it took up to 212 W on load with only overclocked cpu and i plan to overclock around there in the near future

im not going to buy two 6670's this year but next year i'll most likely so wondering if i should start saving up for a good PSU

also you dont have to answer this but you guys think it can power a single 6950 since if next year amd's trinity (bulldozer with integrated GPU) comes out for FM1 socket i might buy 1 and a 6950 if the price is right

Well it looks like the 6670 draws somewhere between 75-92W under full load or a max of ~6-8 amps.

If you put the CPU on one 12v rail and the two 6670's on the other 12V rail you should be OK if the PSU really delivers the full 18A & 20A advertised on the 12v rails. The reason I say this is because they do not show the full load available on the two rails in total wattage as better PSU makers do.

The PSU should just be able to power a single 6950 which uses 182W or ~15 amps.

1) I say go for a better brand of power supply first, then worry about the graphics card. I've had very bad experiences with Ultra power supplies. I would suggest an Antec, Corsair, or a Seasonic PSU. They are much more reliable and stable than Ultra.

2) I wouldn't be set on the graphics card till it comes time for you actually buy one. Also, Crossfiring two lower end cards is a waste. Better off just buying one more powerful card. It will give you way better performance.

thanks for replies and the reason im getting a lower end card instead of a single more powerful card is because i'm on a budget but i could save up to get something better

soon i'll have around 200$ to spend probably more but i plan on getting a 50$ cpu cooler since im still running on stock fan

saw some benchmarks of 6670's in crossfire and now thinking about getting the 6850 but will it be bottlenecked by my cpu?

and will this psu be powerful enough to slightly overclock the 6850?

and ill try to get enough money for a good antec 750w next year or another high quality brand psu if i see one on sale
