AS stated I have an Antec Fusion HTPC case (the one with the VFD but no IR or remote). I want to get a Radeon 7770 or 7850 or an equivalent Nvidia card, I dont want to spend a lot and I want to know if my PSU will give me problems? I believe its around 400-450W... I'm not sure how to confirm it.
Thanks, sounds like good advice. Is there a great deal of difference between the 2? If the 7850 is a lot better then I might take the gamble. My PSU is by Antec so I don't know what that means WRT quality.
