    According to Nvidia, the maximum power the gtx560 can use is 150W = 150W/12V = 12.5 Amp. That is standard reference card with 1GB of memory so yours will be slightly more. I expect it would be split. In any case if you use your two 30A you should be good.
    yeah.. but my question is.. what does the card really wants?
    the box says 24 amps..
    is it 24 amps per conection? or 24 total...

    It is 12.5A total. The card only uses 150W. I don't know where they got 24. What brand?

    Your card can draw up to 75W from the PCI-E slot (6.25A) . The auxiliary connectors allow it to draw more. A 6 pin Aux PCI-e power connector is rated at 75W (6.25A), an 8 pin at 150W (12.5A). The power will be shared among them.

    With two 6 pin aux connectors, you should be safe up to 3 x 75W = 225W, more than the 150W maximum for your card, assuming the card draws power from the PCI-E slot. Even if it doesn't the two PCI-E aux connectors will give you 150W an only draw up to 6.25 A each.

    I believe they are talking about the 12V rail must supply minimum of 24 amps total which is 288W - enough for a processor and a 150W graphics card + disk/etc. They do this because some PSU have lower than that on their 12V even though it may have a total 450W. That card is 150W maximum = 12.5A.

    Their spec sheet says they have a 24x7 tech support - though you may not get a knowledgeable tech for all I know - you can ask them.

    In any case, the power will be split between the two PCI-e aux connectors so you are OK.

    Here is a link to the power measurement of a EVGA 560 Ti Superclocked. It draws more power than the non-Ti. They measured 190W Max = 16 Amp

    Specs on that Acer,

    Short and simple answer is that there is nothing to upgrade. You want a faster GPU in your laptop, you're going to have to buy a new laptop.

    I recently updated an old Dell Dimension E310 desktop, so it could run Windows Aero on Windows 7.
    Installed a PNY Geforce 8400GS PCI video card. Windows Aero works perfectly OK now.
    The problem is, when playing a DVD movie with subtitles, it stutters a lot.
    The stock PSU is 230 watts. I read in the 1st post a Geforce 8400GS needs 300 watts. Can this be the cause? CPU is a Pentium 4 2.8 ghz, 2 gb RAM.
    Thanks in advance.
