Can my PSU handle the HD 4850 or 4870?

Ok, so this is my PSU

http://www.cluboverclocker.com/reviews/power/antec/TruepowerTrio550/index.htm Can it handle?

Help, thanks.

4850 yes, 4870 I think it will and it has the connections for both but not crossfire.

That psu has 42A on the 12V line, which can even power a 4870x2. (the 4870x2 takes 250W IIRC, which is 21A).Mr_NoName111
