Well I've been chugging along with this for the past 19 months: P3-700e overclocked to 933MHz 512mb pc133 GeForce2 GTS 32mb etc. and now I'll be upgrading...I have all my components decided except the power supply. I know AMD's are really picky and power hungry and I also hear the GF4 needs a nice power supply. I've narrowed it down to these and please don't suggest other ones, I can get these for good prices: Antec PP412X: More wattage (400w), 245 watt (!) combined on 3.3v & 5v, but possibly louder? Enermax EG365P-VE FCA: Less wattage (350w), only 185 watt combined on the 3.3v and 5v rails, but you can tone the fan speed way down to reduce noise. Noise *is* a concern to me but it's not the main concern (stability is). I also hear that the Antec has a ADDA fan in it, and aren't these relatively quiet? If I had the enermax I would turn the fan speed dial down all the way most likely. This is all the stuff it will have to power: -ECS K7S5A -Athlon XP 1800+ (no overclocking planned at this point) -512MB Samsung DDR (PC2100) -Abit GeForce 4 Ti4200 (overclocked to Ti4400 speeds and hopefully Ti4600 speeds) -SB Audigy -40GB Maxtor 7200rpm -15GB Maxtor 7200rpm -LG CDRW -Toshiba DVD-ROM -Linksys NIC -Firewire card (usually 1 or 2 firewire devices hooked up, but I don't think it's a real issue since the ext. HD is externally powered and the DV-Camera only sends data) -Floppy Both power supplies are about the same price, but I'm torn between them. Won't be ordering the parts til next week. Anyone?
