GUIDE [HOW TO] - Installing Cathode Lights

post #1 of 2
Thread Starter 
This is a simple guide showing you how to wire the light to the ends of the molex connector on your power supply.

Not everyone has easy access to a cathode light with a molex connector meant for computers. In my case, I used a cathode light meant to be used for motorcycles. It didnt have a molex connector so I improvised.

STEPS:

1) Make sure your cathode lights have an inverter. The inverter converts the 12v of your PSU to 1000+v needed to light the cathode tube.
(NOTE: Make sure your inverter takes in 12v DC power)

2) If your inverter does not have a molex connector get any old unused male molex plug. I took mine from a SATA to molex adapter.



3) Get any working power supply and connect the green wire to the black wire beside it using a paper clip. It looks like the red wire is beside the green wire in the picture but it is in fact a black wire.

This is to get the PSU to work if it is not connected to your motherboard. Otherwise disregard this step.



4) Plug in the male molex connector to the female connector of the PSU



5) Connect the red wire of the inverter to the yellow wire of the PSU. This is the 12v line. Next, connect the black wire of the inverter to the black wire on the molex.



6) Make sure the bare wires do not touch each other or any other metal wires. Power up the PSU and the cathodes should light up!





This is what happens if you plug the red wire of the inverter to the red wire (5v) of the PSU. Only half the tube lights up. This is a very common mistake because it seems logical that the red wire of the inverter should match up to the red wire on the PSU but this is not the way to install it.



FINISHED! Now sleeve the wires or wrap the spliced wires with electrical tape to prevent a short. Next, mount the cathode tubes and inverter inside your case using double sided 3M tape and you are done!
