    i upgraded my video card to a ati radeon 9800 from a geforce 4 mx 440.

    ati says i need a 300w power supply, my pc has a 250w.

    the only devices hooked up to my power supply are two cd drives(one dvd-rw, one cd-rom) the floppy drive, and the hard drive. and i guess the motherboard is included right?

    i disconnected the cd-rom drive since i dont use it much.

    would there still be a problem? everything seems fine so far.

    It's a recommendation that I'd follow. The power supply is one of the most important parts of the computer and any trouble with power can lead to bad things. You may see no trouble but you could get to the edge of continuous power, not peaks, and not know it then a spike or heat could disable or even fry parts such as the mother board.

    Well, your choice but disconnecting that one drive is a very small power savings since at standby it's probably using no more than a couple watts. In use that'll jump to about 70. My experience on this site with folks who've used company tech support doesn't give me a lot of confidence.

    i know spikes are pretty umcommon, and i dont put a heavy work load on my box(games, imaging programs, etc etc).

    do you think im running a risk for the time being until i get some money to buy a power supply? say about 4-5 days?

    If it were me, and maybe others here might chime in, I'd wait the 4 or 5 days and get the new supply then have fun. It's not worth the risk at least for me. You could always put the old card in for a few days.

    Hi and welcome. I must wonder about the logic in the video card upgrade, since you said that you don't play games, or use imaging programs :confused:

    Howdy folks...

    platonjk...

    I think the HP tech is giving you the brush off, IMHO like what the others have said, just unplugging the CD-ROM isn't going to give you the needed power needed for this video card...

    Now you may be able to use it with the current PSU but...eventually sooner or later the PSU will fail, and it's been my experience that when a PSU fails it sometimes takes out other componets of the computer...

    Choice is yours...

    But if it were mine...I'd upgrade the PSU, but that's just me :D...

    As I see it, ATI's wattage recommendation can not have much to do with the power usage of the card itself. It is never going to draw 250 watts alone. So if the total demand on the board remains below 250 watts, and the rails are deliverying the amperage, I can't see how 250 is a problem.

    I expect if the board starts to get loaded with other peripherals, it will shut down when the draw gets too high for the transformer.

    Candy,
    I was a pro photographer by trade for many years. I play no games, because that's not why I own computers), but I do some involved graphics processing. Long before I did that though I discovered what a huge difference in graphics a really good and fast video card will make, probably because of how sensitive I am to color and refresh rate. While I won't go top of the line with video card I will get runnerup and never less than 256 meg. I mean let's face it we spend a lot of time staring at a screen close up so the best and easiest thing we can do for our eyes, is the most reassuring investment we can make so no bargains in monitors or video cards for this guy!

    Your P/S is pretty marginal for the system. Remember, if it goes, there's a chance that it'll take some other part with it.

    I suggest putting the old one back in untill you get enough money for the new PSU

    i put the old card in and got a new power supply(300w, compusa brand. got it real cheap at 15 bucks)

    also i wanted to upgrade the graphics card because im planning on getting a tv tuner card and was wondering if a graphics card would make a difference.

    the graphics card was free so i thought what the heck.

    thanks guys.

    Start planning replacement now for bargain psu, it will go in one wrong shutdown, and probably take cpu and motherboard with it.
