    If you bought one then the fix to put more power on the cable should be fine. The problem is overrated imo. However the better advice is just wait for the aftermarket cards with proper power and cooling - the stock cooler is pretty weak, it really needs more power to o/c, and resale of stock cards will be bad. The only exception is if you think you can find one of those fake 4GB cards which is actually an 8GB one.

    That said this is another lesson from AMD in how to completely botch a release - as by the time the 480 aftermarket cards arrive the 1060 hype machine will be in full force and the 480 will old hat.

    I can't see the 1060 being in the same price range as the 480, at a guess I'd say it's going to cost around £280-300.

    People next expected a cheap 970 last time, Depends how much Nvidia wants to target that market area. It might not be bang on £200 but it could be near enough.

    I do not remember the power consumption been an issue when NV cards like the 750Ti draw 100-140W constantly from the PCI-E.
    Now everyone up on their arms because sometimes the RX480 consumes briefly 80W from the 75W PCI-E?

    Hypocrisy to all it's glory.

    nv wont leave a £200 gap in the range - the 1060 will be £300

    We will know inside 24hours either way. Would it shock me if it was £300 not really, But it would not shock me if a none founders edition was close to £200.

    We know very little about this really, If its the same gpu as the 1070 just cut down then it could be cheap.

    I think it's more to do with the way it draws it power than the actual power draw, if I've understood correctly AMD have split the card in two when it comes to power deliver, instead of aggregating the power draw across both paths.

    Except it isn't about the Wattage....It's about the current (Amps).
    Toms Hardware measured the card pulling 6.74A through the 12V pins...The PCIE specification states 5.5A as the maximum.

    Ahem: wattage is amps times volts. So, saying "5.5A from the 12V pin is the maximum" is literally the same as saying "66W from the 12V pin is the maximum."

    If you have two of the three, you can always get the third. 2A at 240V? 480W. 500W at 10V? 50A. 5W at 2A? Well, that must be a 2.5V power supply.

    Toms hardware has the 750 ti pulling 62-68 watts, GPU only, Bit-tech has a system including one pulling +74 watts under load (increased gpu and cpu) which probably agrees with the 62-68w from toms. given the slot is rated for 66-71w or thereabouts, this is a touch high, but not a big deal.

    The issue with the RX 480 is that they have been measured to be pulling 80w consistently(average) through the slot alone at stock/reference speeds and at 90+ consistently with any kind of overclock (which will include factory overclocks) which is significantly over that 66-71 that the slot is built for.
