X-bit Presents: Power Supply Unit Testing Methodology

Sidney · 2nd February 2005, 00:06

Recently, an interesting solution has been implemented in expensive PSUs (for example, in models from OCZ Technology or Antec): auxiliary regulators on saturated chokes are installed not only on the +3.3v rail, but also on the +12v and +5v rails. This ensures a very good (as computer power supplies go) regulation coefficient of all output voltages and also allows to adjust each voltage independently from the others by changing the parameters of its own auxiliary regulator. Once again, this design is a prerogative of expensive PSU models while middle-range products have the above-described dependence of their output voltages on the load on each of the power rails.
