Hi there,

I recently got the Raijintek orcus 240 and it works like a charm. The problem is that the RGB hub still needs to be connected to the mainboard (Asus maximus xi hero). The cable just isn't labled as a regular 12V RGB cable (it fits in every direction and the manual doenst state which way it should fit)

Has anyone managed to install that thing properly?
Is anything at risk of being damaged if the cable is oriented incorrectly?

Thanks in advance!

There's supposed to be a notch or catch or key or even a '1' on one side of the connector which lines up with the header. If there isn't any, you'll have to guess.

Diodes are 1-way usually, and leds are most definitely polarity sensitive, so if it plugs in and doesn't work, flip it.
Rgb works by controlling amperage through 3x diodes. The higher the current, the brighter the individual led. So if you have 0.2A through red, 0.2A through blue and 0.0A through green, the red+blue led in the bulb light up, green doesn't and your eyes interpret that as purple.

4 pins. V/R/G/B, one is V+, the other 3 are basically going to ground. So Yes, orientation matters.

Thanks for the reply! How does one figure out the proper orientation when the manual and the website both lack the information though? Thanks in advance!

Thank you so much! I will try it this weekend. :)

Since I didn't have time this weekend I still need to try to connect that thing. The cable that is supposed to connect the hub to the MB looks like thishttps://www.raijintek.com/en/controlset-03.html
I am kind of hesitant to just connect and flip if it doesn't work, since I heard that it might cause damage. As far as I can tell there is not real indicator for the 12V pin, just the hook on the top of the cable. Is that supposed to be the side that points upwards?
Sorry to bother you again Sir

After rethinking everything I just went for it and it worked. I have the notches pointing upwards when aligned with the RGB header of the MB. Hope that helps anyone having the same problem as me. Thank you again @Karadjgne for your help!
