The volt rating of the RED WIRE in a PSU is _____.

Explanation:
In PC power supplies, wire colors indicate the voltage each wire carries. Red is the standard color for +5V. This convention helps identify rails quickly: yellow is +12V, orange is +3.3V, black is ground, and other colors cover additional rails like +5VSB. So the red wire provides +5V, a rail traditionally used to power logic circuits and components on the motherboard.
