My HTPC has an Athlon XP 3200+ in it (77 watts) but I may swap that with my Sempron 3300+ (seems to be the same except 64 watts, see my thread in CPUs). In any case, I'm probably going to get a Sapphire HD Radeon 2400 Pro (AGP) and I suspect I'd need a new PSU for it. I do want to replace the current unit with something quieter anyway; what do you recommend that's quiet and enough to run these power hungry beasts at stock? Also figure on 2 or 3 optical drives, 1 HDD for now.
