So, I took delivery of my CTO mac pro today (2.26 octo, 4870, airport)...put my HDDs and eSata card in it...go to plug in power and I hear loud cracks and flash of light (electricity). Removed everything down to stock, and it plugged in...but buzzed audibly when turned on. Added eSata card, same thing. Added HDDs....very loud buzzing when plugged in - not willing to turn on. Would I be right to confirm that my 6k Mac has a dead PSU?
