[SOLVED] Gigabyte x99 Ultra Gaming + LED Strips

[insertcdhere]

Idk if its been discussed before so ill apologize in advance if it has; On the Gigabyte x99 Ultra Gaming motherboard it has a RGB header. I plan on using 2 16.4ft RGB strips for a project. Would i be able to connect both strips to the MOBO? I plan on cutting the 12v off the MOBO to wire in a separate 12v 20a PSU and leave just the "R,G,B" connected to the motherboard. Would this setup work or would i risk damaging something?

Sorry, you can use less than 1/2 that RGB strip with your MB, otherwise you will kill that header or maybe the MB too, because according to the manual ( page 26), the RGB header can only support up to maximum length of 2m ( or 6.5ft) the RGB LED strip.

The motherboard WONT be used to power the LEDs, the 12v 20amp power supply will provide the power. The header will JUST control the R G B which are grounds. Im not very electrical savvy so im not sure if supplying 12v and grounding from a different source will cause damage.

But from what I know, if you use the RGB pins from the RGB header only, and power the strips with the PSU, if you find the way that will be a big question, and the strips will light up, but you can't control the RGB. By the way I don't know how you power the strips with only one +12V pin from the PSU, there is not a ground wire connector, that means it is the open cycle.

If you want to finish this project, you will need a or two RGB hub controller(s), and don't use the RGB header from the MB.
