Except the very reason the discussion came up is it isn't, when a person with a 650 watt power supply (high quality, brand new) has to run his card in power saving mode to avoid system shut down and other crashes/issues, making it clear it is a power issue,, and tries to blame the card and AMD, all while ignoring their minimum recommended requirements. But.. each to there own. If a person wants to cripple his investment by running it in power saving mode and not being allowed to use it at it's full potential because the person doesn't want to admit it is a power issue, or others trying to argue it couldn't possibly be the power supply, so be it. Not my problem. I have never had an issue do to power, but then again, I never try to get by with what should be enough, and always get above the minimum requirements per the manufactor. Becuase what "should be enough" does not take in account for all the variables that can effect the draw on a power supply, or the output of the power supply. All it takes for a "should be enoigh" power supply to be a " not enough" power supply is live in an area with a bad power grid that is not effectively supplying clean power.
