I have a ChiefMax 550 watt ATX switching power supply problem. When I hit the power button the fan jerks and than nothing. I took it out of the computer and jumpered the green start wire to a black wire and hooked a CD Rom for a load and when I put power on it the Fan jerks the light on the CD Rom flashes and thats it. I have looked at all the components and no blown fuse, no bulging cap's and nothing that shows any sign of failure. I know it's cheaper to buy another but I'm fooling around trying to learn electronics, what better way than this haha. Does anyone have any idea what I should check first, would it be the high voltage side. also maybe sombody knows where i could get a schematic for this model?? Jim
