I'm building my first athlon system and don't know what size power supply to get.Parts I am planning to put in are 1.4ghz T-bird,Iwill kk266+R mobo,4-wd 30gb 7200rpm hard drives set @ raid 0,cd writer(undecided),zip drive,floppy drive,dvd drive,Ati AIW,soundblaster live 5.1,nic & 3 case fans.Is a 400w power supply enough to power all this or do I need to go larger????

Well, you can't go wrong with more power.. but 400w should suffice in this setup.

nice choice on the mobo. I'm running a very similar setup to what yours will be and I'm using a Sparkle 350W. CPU is a 1.33 @ 1.53 (161 FSB) and all my voltages are above where they should be. 5v rail is 5.12-5.20v, 12v is 12.07-12.10 and my I/O (3.3v) is set to +10% which gives me 3.56v.
