can my psu handle these cards?

as some of you may know,ive made a couple of topics regarding my psu because i want to upgrade my video card.i want to upgrade from my 3850 to either the 4770,5750 or the 5770,but im not sure if my psu could handle those cards.it says it ouputs a total of 29 amps through both 12v rails,which are at 10v btw.so that would be 290 watts of power through the 12v(10v in this case) rails,right?so i guess it would support those cards?thanks for reading.

edit:forgot to mention that it is a non brand 425w psu

yes

Well yeah, it should be plenty.

I have a 4850HD and it's over clocked, with 500 watts.

But it depends on other specs if you want to over clock and that good stuff.

Open your case and find the sticker on it that has the rails and amps for the rails on it.

What your looking for is +12v @ XXa.

Your also looking for like max +12v combined and stuff like that if there are multiple +12v which I assume there are going to be.
