    Its a lot more accurate than most peoples misconceptions of computer power requirements.

    However power usage is rated in Watts, thats why your meter counts in kWh.. Maximum amperate is important for powering devices from your rails, but again thats PSU efficency playing into effect again.. But generally speaking 12v rails on all quality PSUs would be very difficult to max out without being a total numpty.

    My Macron 300w with a knackered fan was stable on my machine where my 450w Qtec wasnt, not quite sure what your getting at

    Exactly that. 300W is enough for anyone, but buy a crappy PSU and it won't be.

    I bought my s12-500w mainly for it's quietness and efficiency. I know it's more power than I need but the 430w model had no pci-e power connectors and I knew I would be using most of the molex connectors. Therefore I didn't fancy an adapter to power my x800xt.

    Also if i do any upgrades that need more power the psu will be able to take the strain without problems and not generate excessive electricity bills through inefficiency. Wish I'd waited a bit before buying it though, at the time of my purchase there was only one place in the uk that sold them because they were brand new and seasonic had no real presence in the uk market.

    Nvidia recommends a 500W PSU as a minimum for SLI for a reason you know.

    mabee it wasnt the lack of power, i could be in a bad powersupply that it had huge fluctuations that the hard drive couldnt handle, whatever just seems good to get a good psu, a mate of mine had a generic one of his explode a few weeks ago, sparks and smoke everywhere apparantly, although the rest of the pc lived

    It's not misleading. Please have a closer look again

    "ATTENTION:
    The total Watts is important but the Total Amperage Available on the +12V Rail(s) is the most important, followed by the +5V amperage and then the +3.3V amperage. Because of the increased power consumption of the new high-power video cards the recommended minimum for +12V is 24A."
