Found on the back of the PSU is three LEDs along with three potentiometers for voltage adjustment from the outside of the case. The LEDs are tri-colored to allow voltage warnings for both over and under voltage. An over voltage will turn the corresponding LED red and an under voltage will turn the LED yellow.
