when it comes to picking a Power-Supply that the graphics card requires, most inexperienced users will opt for the generic, no-name 550W PSU which glows in 20 different ways and retails for less than $30. Yep, nothing like protecting a $400 investment with a glowing, $30 device that promises twice the max voltage of competitor's units.
