SAQ wrote:Basic thing to keep in mind: on most cheap SMPSUs (the Fuel's is probably in this category, all PC supplies are), the voltage regulation reference is taken from one line and the other supplies are expected to track along with it, which they do mostly. Are the other lines also off on voltage?

Although i have no idea if they really use the stock model or even whether the pinout is the same..

Did you ever consider the possibility that the chips themselves might indeed be ok but the checking /algorithm/ is faulty?

Shouldnt than sgi can fixed that with a firmware upgrade? According to the post sgi replaced the boards.
