    Hey guyz, does anyone here know if a 250 Watts power supply is sufficient enough for a Radeon 9800 Pro videocard? It is a 250 Watt power supply from an HP computer by the way, which is currently hooked up to a 80 gig hard drive, 1 dvd rom, 1 dvd burner, floppy drive, and one case fan. Thanx guyz

    There is only one way to find out buddy ;) try it, the worst that will happen is nothing :)

    But do get a good 400 or 450 watt PSU so you can add more stuff later one.

    I run a 400 genric PSU and my system is yet to lock, crash or BSOD :D

    yeah, thanx for da suggestions, but yeah, do you know if any of the power supplies that i buy would fit a compact case, the kind of case that barely have any legroom, and could only fit a micro ATX motherboard or uATX.(man I hate HP brand computers!! Grrr.) well, that aside, any other insights on the topic?

    Err.. on the side of caution, if you do overload your powersupply excessively then it will do some ugly things (and they don't smell too good either...).

    Also, does HP use its own custom PSU? Then you might not be able to get one that fits, but I suppose you could try gutting one from a SFF PC...

    I don't really know if they are custom PSU's or not, all it says on the PSU is 250 Watts, does not indicate any brand name whatsoever....But I suspect my PSU to be smaller than the normal ones, since my case is pretty small as well.....how can I find a PSU that fits? do you guyz know of any place that would sell smaller size psu's?

    no, get 350 watt psu , but soon you will replace your card with a better 1 so get 480 psu so u dont have to upgrade later.

    yeah dominant1 I would love to upgrade my PSU, but the problem is that I think my rig is fitted with a smaller sized PSU, not the standard ATX psu's, I've compared the sizes of the psu in my rig, to a friend of mines, which has a standard ATX case, and my seems to be a little bit smaller. The problem is, where do I find smaller size psu's? I have no idea where to find such a PSU, as most of them listed on the internet are Standard ATX ones. So I just wanted to know if 250 watts is good enough to run a 9800 Pro. Because upgrading my psu would be quite difficult.

    You're probably looking for a 1 unit sized PSU.
    HTPC and some SFF PC's [Not Shuttle] use the same type, so you're better off searching for PSU's for them.

    List your current PSU's amperage ratings [Can be found on PSU sticker].

    Go spend 80 bucks and get a new case with a high watt PSU. Transfer your stuff and be done with it.:D

    A 9800Pro need's a min of at least 300 Watts PSU, so really aim for a 350 > 450 to keep the system running smooth.

    Agreed. Thats the most sensible and cost-effective solution.

    Hey,
    i had the same problem with my HP awhile back, i'm guessing you might have the same model as me, the pavilion t134a. If so, don't worry about the size of the power supply, any normal sized one will go in there fine. I replaced mine with a 400watt. You definetly need a better power supply than the one that comes with the pc, my 9800 pro wouldn't run with it (250watt).

    Almost everything in mine has been modded or replaced, the only thing left standard is the exhaust fan, CPU and case :D.

    Here are some pics of what mine looked like a couple months ago before i replaced the motherboard and sleeved the cables: (sorry for the poor quality, mobile phone camera:D )

    9800pros do fine inside shuttle boxes and they have 250w PSUs at best. To answer the original post, yes a 250w PSU will be enough for the 9800pro. However, there is wisdom in upgrading your PSU. Get the most you can afford.

    Use http://www.jscustompcs.com/power_supply/ tool. I filled it in and it's too close to call. It depends a bit on your CPU. You could give it a shot, but it doesn't look good.

    If you want to be more sure before buying, add a few light bulbs on the 12V on your current setup. Not exactly fail safe, but it could give ya an indication.
