Yes, though they are for different voltages, typically 3.3V and 2.5V or
1.8V, see the voltage monitoring in the BIOS or MB monitor for the
values for a particular board.
You'll find two inductors, probably toroids, and a group of tall
aluminium electrolytic capacitors in the area. These

Assumed there should be a linear voltage regulator able to provide the

If you use it as voltage stabiliser + heater, it provides 100%
efficiency too. It's simply a question of the point of view.

Switching regulator MOSFETs provide the 3.3, 5/5VSB, and 12VDC output

had a single 12V regulator
