I want to wire my case's power_on LED so I can find it in the dark to turn on my PC. The mother board is a Z270 Taichi.

Has anyone done something like this?

Guess I'll be answering my own question.

The motherboard has a USB 3 A-Type female connector. The USB is powered prior to turning on the computer.

Parts List
Old USB 2 printer cable
560 ohm resistor
3-pin fan power cable extension.

The 3-pin fan power cable extension was used to connect the PC case's Power LED + and - connection.

The old USB 2 printer cable connected to the motherboard USB.

The 560 ohm resistor was used to limit current to the case's power switch LED.

Works just the way I need.
