Default Re: Power supply build quality pictorial. part 2

Ruky, my WAG is that that is a ~200W Newton Power (that "N" logo near the toroidal input inductor suggests this) or Delta, possibly mid 1990s vintage. I'm guessing the power based on the 390uF input caps, and the 1002 might be a Delta ASIC supervisor IC (Newton is owned by Delta).

The 10A 12V rectifier and 20A rectifiers for the 5V and 3.3V are consistent with that time frame and power level. Likewise the PJ series output caps. The 5A standby rectifier seems over-rated for the common .5A-1A standby current of that time-frame, though.
