I've just been having a look at the Sapphire forums and I see that a lot of people are having rebooting problems with this card....now I think I noticed is that a lot of them have ****** PSU with less than 480w and less than 30A on the 12v.
On question I have to ask is, Is my Antec 550W truepower 2 going to be enough?....
it has 36A on it's 12v rails, I would think that it should be plenty.
