    It depends on all the other components your using. Say your just using one Hard Drive and a CDROM drive with that and no more than two or three fans and no lighting in the case than thats fine. Full details on what your using it for would be nice :)

    The machine my son is using right now has a Duron 950, 448mb RAM, CD ROM, 2 trilight 80mm fans, and a 12"neon tube all running on a cheap 250watt PSU. Not saying that you will get the same mileage but it can be done.

    as long as the 12v rail puts out enough amps, you should be OK.
    most 250W supplies have weak 12v rail

    try this 'psu wattage calculator' to see if a 250W psu is enough (general estamate only)

    also seen in this thread: http://forums.tweaktown.com/showthre...threadid=16676

    but if the rest of the hardware is from the same era and in a typical config then a 250W psu should been enough, but like it's already been said the combined total of your hardware is what you need to be worried about and the link i posted will help you with
    I've gone too far and need to move on!

    From that URL...
    The Wattages listed below are maximum potential wattages for each item. The total amount this calculator figures is for all devices running at peak utilization.
    Ok, you must note that those are the maximum possible draw of power of all devices in the category. Only the processor/video/fan/pci cards are correct. Everything else is highly exaggerated. For example, a hard drive often requires as much as 15-20 watts during BOOT... and that only takes just 2-3 seconds to reach full spindle speed. Your processor will never be maxed out at boot, therefore you can figure 8-10 watts per drive.

    CD-Rom drives @ 20 watts? LOL, they take no power unless they are spinning, and even then we're talkin maybe 10-14 for a really fast drive.

    To conclude: I entered in my system specs into that page, and it suggested to me that I need a 500 Watt supply. I have an Antec 330 Watt, and it has never been a problem. (And before I got my Antec case 2 years ago, i was running the exact same system with a GENERIC 300 Watt supply...

    So you can take whatever that site suggests and chop off 40 percent or so...

    Ditto, I entered in my system and it said I should have a 371watt PSU. I've been running it on this generic Dell PSU for two years, not a hitch. For a Duron 900, you should be fine. : peace2: Mista K6
