Yea, ain't he the World Record holder for the FX 8370?

In all likelihood nobody knows this stuff like The Stilt.

https://en.wikipedia.org/wiki/Voltage_drop
Quote:
Voltage drop describes how the supplied energy of a voltage source is reduced as electric current moves through the passive elements (elements that do not supply voltage) of an electrical circuit. Voltage drops across internal resistances of the source, across conductors, across contacts, and across connectors are undesired; supplied energy is lost (dissipated). Voltage drops across loads and across other active circuit elements are desired; supplied energy performs useful work.
Bascally saying. Voltage drops because the resistance of voltage output to CPU changes when load occurs.
When hotter the cpu and metal tracks where voltage and current goes may have more mroe resistance, due to increaced heat.
Therfore, power is lost in those areas, simularyly when a transitor uses more power heat is generated and power is lossed there.
Equating to change in voltage supply

Theres voltage drop, when theres an load or a great load. Voltage drop will be insane when theres a overload on the powersupply.
When theres a great load the powersupply gets hot and resitance will increace

Quote:
For example, an electric space heater may have a resistance of ten ohms, and the wires which supply it may have a resistance of 0.2 ohms, about 2% of the total circuit resistance. This means that approximately 2% of the supplied voltage is lost in the wire itself. Excessive voltage drop may result in unsatisfactory operation of, and damage to, electrical and electronic equipment.
Further more, heres how I understand it. wihout voltage regulating circuit voltage drop will always happen.
and voltage drop is caused whenver electric is converted into light, heat, sound
