The red wire in a standard PSU provides which voltage?

Explanation:
Wiring color coding in ATX power supplies maps voltages to colors, with red indicating +5V. This rail powers digital logic on the motherboard and many older components that rely on five volts. Other rails use different colors: +3.3V is orange, +12V is yellow, and -12V is blue. A +5V standby rail (used when the power is off but the system can wake up) is purple. The -5V level is generally not used in modern PSUs. So the red wire provides the +5V rail.
