    Default IBM ThinkCentre MT-M 8188 Upgrading Graphics Card ...No monitor signal!

    This is my first attempt at an upgrade!
    My PCU is 230 watt only and I've put in a WinFast A7600 GSTDH that requires 300 watts. I thought at least that the card would at least be recognized; But the monitor gets no signal. The current graphics card is integrated and works just OK with Windows 7. I'm unable to install drivers etc from CD without having the WinFast installed to be recognized. Only the fan spins when the WF is installed. I'm thinking of downloading drivers for the WF using the integrated graphics but maybe this won't work either. Could it be I just won't get anywhere without first upgrading the PCU to 300 watts?

    The WinFast slots in AGP.

    I would replace the PSU for a start. To something like 500-600W. 300 is still too low

    Is the card 1.5v?? It looks like it may have to be. If it's like old ASUS mobos, I think AGP cards were either 3 or 1.5v. If you put the wrong one in it wouldnt work (on ASUS boards), there was an LED beside the AGP port. If it came on, it was the wrong voltage.

    And if you put the wrong card in, it could fry the port

    Finding a PSU above 300W with required connections and size to fit will be an issue I think.

    Can't find any info on box, manual, or card, if 3or 1.5v.
    The mobo is labeled IBM. No Led. No beeps when insalled

    Problem solved; F1 - video setting change from PCI to AGP. Graphics card working perfect.

    Good on you, I was going to suggest checking the BIOS (honest). The PSU may be a bit marginal but the "minimum" specified PSU values are always given a very large safety margin to allow for whatever else you may have installed and for the unfortunately common practice over wildly exaggerated wattage ratings by some PSU manufacturers. Older PC's seldom need very large PSU's, 400W was huge not that many years ago.

    A calculator like http://www.extreme.outervision.com/p...ulatorlite.jsp will give a good approximation of what's actually required, and even then the recommended value has a bit of a margin.

    According to this page http://www.tomshardware.com/reviews/...er,2122-6.html a 7600GS like on the card you mentioned uses approximately 27 watts under load, hardly requiring of a 500-600W power supply sorry Speedy.

    I have a range of cards here I'm experimenting with litecoin mining with. It may interest you to know I've had a 7970 running at full load off a coolermaster 400W PSU - power draw measured at the wall = 370W (and you have to factor in the 75-80% efficiency to get the actual output so 280-300W being drawn from the PSU). The recommended PSU for a 7970 is generally 600-650W. I wouldn't recommend using a 400w for that card long term but it proves how much the recommendations are inflated by, even if you factor in another 95W for a high end PSU at 100% load (litecoin mining is 1-2% and uses a low end CPU. Moral of the story - stick with quality PSUs and you can use a lot less than people think (I'm making no claims regarding coolermaster, just happened to have it around)

    Thanks Dugimodo; Must admit I googled Bios and then twigged onto F1. Surprised myself how easy it was, here me thinking one had to be an IT nerd. Yeah I read 32 watts but thought maybe with video games the power use would increase a lot. I have a couple of games that came in the box but not game to push the loading up. I'm looking at replacing the PSU up to 3-400 watts. It would be great if I could just plug my existing wiring into a new PSU but looks like one needs to get the right PSU with attached plugs. Found this one Evo Labs 400W on Ebay CHEAP AT under NZ$30 delivered from UK. Cheap may not be good! And not quite sure it has all the plugs I'll need.

    { Shudders} Cheap and good PSU don't go together in the same sentence. Esp that cheap -- it will be rubbish. A PSU is one item you cant really afford to be skimping on, cheap ones (mean low quality) when they play up & they will (sooner or later) they can take out the whole PC.

    Just looked and theres next to no real world reviews on them = a worry.

    At that price I suspect it would be no more powerful than the original PSU, but more to the point: also much worse quality.

    Also note that the overall watts rating on the label means practically nothing because without knowing how much current is supplied on each rail, you only get half the picture.

    Besides that, ultra-cheap PSUs usually outright lie about their rating anyway, or at the very least, it's the peak rating, not continuous.
