650w psu and 6950 2gb crossfire

Hello,

Looking to upgrade my video card to the best it can handle and was looking at maybe 6950 crossfire/ 6850 crossfire / 560 TI sli or maybe a gtx 580

Im using a Antec Truepower Trio 650w had it for about 3 years.

i think this is the specs http://www.antec.com/specs/TP3_650_spe.html

using the power calculator on the eXtreme site seems to suggest its ok http://extreme.outervision.com/PSUEngine

PC Specs
- i5 750 oc default voltage
- Gigabyte ga-p55-ud4p
- 3 sata 7200 rpm 1 5200 rpm HDD
- 2 sticks DDR 3
- 8800 gt
- 2x 20cm fan
- 3x 140mm fan

would the current required be an issue?

    Thanks for the reply :) just wondering according to this http://www.bit-tech.net/custompc/reviews/111407/antec-truepower-trio-tp3-650.html Rail 3 12v outputs to the 2 pci-e ports which has 19A so would crossfire 6850s be overloading it

    maybe best to just get a 6970 and wait till i upgrade the psu and get another 6970 then

    Need to read better reviews

    " And on the load tester, I found that there actually is no OCP, so there is no 19A per 12V rail "limit" either. Just seems to be a single +12V rail PSU! Which actually isn't such a bad thing, but dammit! The label says I get three +12V rails and the PSU is called the "Trio" after all! "
