I just order a gigabyte radeon HD 4650 (agp) and an amd athlon xp 3200+. Do you think my 350 W PSU will be enough? I will
place them on an asus A7N8X-X motherboard.
no experience with them myself, quick google search they look like decent psu's and your model has 18 amps ... so you should be fine with your cpu/ a 4650
