  • Well, just replaced my mouse and started playing BF3, was on for a couple of hours and poof, my computer died! Checked all of the cables in the back of the computer and all seemed in order back there. I currently have the Gateway LX6810-01 and it has a measely 400 watt power supply. I have recently upgraded my video card to a NVidia Geforce GT545 and did not have any issues with the computer for the last month or so, until now. This computer is 3 years old and I am guessing my power supply just took a dump on me. How do i know what power supply to get, compatible wise?? Or is this even an issue?? That is why i bought the video card that I did because it would run the GT545. Is it possible that the video card was running my power supply to hard so it failed?? Just looking for some input back from you guys to see what you think. Was thinking about getting a 700 watt power supply or so and putting it in, I will see if anyone post on this before I do anything. Thanks

  • First and foremost yes it is possible that your video card was sucking more juice than what was available, I had it happen with my 250GT when I had a 450w, and when I upgraded to a 650w, everything ran smoother, no more issues at all with anything and I got the full performance out of the card. So if your card IS running on a psu that cant fully support its capabilities, it is running at reduced performance.

    Second, if your gonna upgrade, MAKE SURE IT WILL FIT. Some of the premade computers out there come with cases that wont even fit a full size psu, and the max they will go to is like 350-400w.

    Thirdly, if it can fit that size psu, plan ahead, if you plan in the future to have 2 cards, get a bigger psu. If you are planning a new build, get a bigger psu (you can always transfer it over). Some brand names that I trust Coolermaster (own a 1000w right now), Corsair (have owned one in the past, very nice, but more expensive) and Seasonic.

    Personally I would get a 750-850, 850 would be enough to run duals of most cards on the market right now, cept maybe the most high end of cards.

    (On a side note, do you have your onboard video card disabled Witty? If not it is probably using up resources you need. If you want to do this it has to be done through BIOS.)

    Hope this helps,

  • If you're looking at just getting your computer back up and running.

    From the pic below it would seem that the case can accept any standard size ATX power supply (150 mm × 86 mm × 140 mm).
    Gateway LX6810-01
    pic from Newegg.

    Assuming your PC has the same or similar PSU specs as below (not certain, without conformation from Witty.):
    pic from Newegg.
    It's 12 Volt ratings are: +12V1=14.0A, +12V2=15.0A

    Nvidia recommends a +12 Volt current rating of 18 Amps for the GT 545.
    The +12 Volt current rating isn't (or wasn't) enough for the video card.

    The selection below should be plenty for your present needs:
    CORSAIR CX430V2 430 Watt (+12V=28.0A) $29.99 after mail-in rebate

    XFX ProSeries P1-450S-X2B9 450 Watt (+12V=34.0A) $38.99 after mail-in rebate
    http://www.newegg.com/Product/Product.a ... 6817207018

    CORSAIR CX500V2 500 Watt (+12V=34.0A) $39.99 after mail-in rebate
    http://www.newegg.com/Product/Product.a ... 6817139027

    SILVERSTONE ST50F-ES 500 Watt (+12V=34.0A) $59.99
    http://www.newegg.com/Product/Product.a ... 6817256061

    SeaSonic S12II-520 520 Watt (+12V1=20.0A, +12V2=20.0A) $59.99
    http://www.newegg.com/Product/Product.a ... 6817151094

    If you're thinking of building a new more power hungry computer in the future, then get a 750W + PSU. But for your current setup a 700W + PSU would be a little overkill.
