    Hi, just need an advice is it really a must to have a 500 watts power supply than the usual 300 watts power supply for a new casing?

    Specs are P4 524 3.06 - 1mb cache 533mhz / ECS P4M800-M7 audio+vga+lan+8x agp+S.ATA or MSI 865PeNeo3-V i848 audio+lan+8x agp+S.ATA / Seagate 80GB S.ATA / Inno FX5500 256DDR + TV-DVi 128bit / 1GB Kingston DDR400 / LG GS-H20L 16x Lightscribe

    thanks in advance. :)

    I was going to say the same--better off getting a good 300 Watt PS than a crappy 500 Watt.

    The thing is that 95% of the time, that 300 Watts would probably be fine--its only when you may have some peripherals hooked up that are sucking juice or adding new cards or hard drives or optical drives--they all need power. But I would say a basic one hard drive, one optical drive, one video card system probably will do fine with 300.

    I'd stick with a name brand and probably start my search around 400 watts and work up. For the configuration in question, 400W should be plenty.

    Thank you guys for your replies :) I'll check on the links. I'll just have 2 hard drives one internal and the other external and the rest is the specs that I already posted earlier.

    Antec, Enermax, Sparkle, Fortron, OCZ, PC power and cooling to name a few. Epower isn't too bad either.

    Can't do better than PC Power&Cooling but they cost big time.

    Another thought, a 500W high quality PSU will give you roomfor future expansion. I woul dsay 450W is the bare minimum I would use. But then I tend to look ahead at what I want inthe future.
