I'm putting together a new system and wondering if I will end up needing a bigger power supply to give everything enough juice. I don't plan on doing any overclocking (except for maybe my vidcard). I'm going to be running: AthlonXP 2000+ T-bred Vantec Aeroflow heatsink/TMD fan combo Epox 8RDA+ or Soltek SL-75FRN-L nforce2 board (not sure whcih I should get yet, Epox is $24 more). 2x256 PC2700 DDR ram (generic, cas 3 I think, still shopping around, don't want to spend alot) Abit Solureo GF4 Ti4200 128mb 8Xagp Seagate Barracuda IV ata100 HD Liteon 24x10x40x Cdrw Sony 56x CDrom Toshiba 6x DVDrom Soundblaster Live 5.1 pci Anyhow, not a speed demon, but an upgrade to my current Duron 950 setup. So will my Antec 300w PS that came with my case do the job? or should I up it to 350w or 450w? I don't plan on adding anything else to the system, and like I said, not planning on OCing except for alittle with my vidcard. Any suggestions? Thanks!
