Which of the following voltages can be measured from a Molex connector on the power supply? (Select TWO).
The correct answer is C. 5 volts D. 12 volts. A standard 4-pin Molex connector (also called a peripheral or LP4 connector) provides two voltage rails: +5V (red wire) and +12V (yellow wire), along with two ground wires (black). These connectors were traditionally used to power IDE hard drives, optical drives, and case fans…

Explanation
A standard 4-pin Molex connector (also called a peripheral or LP4 connector) provides two voltage rails: +5V (red wire) and +12V (yellow wire), along with two ground wires (black). These connectors were traditionally used to power IDE hard drives, optical drives, and case fans. The other options are incorrect: 1.5V and 3V are not provided by Molex connectors, and 115V is AC wall voltage - power supplies convert AC to DC, so no internal connector carries 115V.
