For any others who come across this thread, I needed a solution to handle the excessive amount of RGB LED I wanted to incorporate into ASUS Aura so it could all be controlled simultaneously.
The solution that worked for me was to buy:
(1) XSPC splitter - Click Here
(2) Thermaltake TT Sync's - Click Here
Step 1 - Connect the XSPC splitter to the 5v Header (DO NOT CONNECT TO 12V Header) on your MB.
Step 2 - Connect the XSPC splitter to SATA power
Step 3 - Connect all of your RGB Lighting to the TT Sync's following the instruction manuals for them
Step 4 - Connect all of your fan controlls for the TT Sync's
Step 5 - Connect both of the TT Sync's 5v Headers to the XSPC Splitter
This worked for me with two TT Sync's but I imagine that since the power is coming from SATA, you could potentially connect eight TT Sync's to the splitter. But I am no expert on this so I could be wrong. Thanks to Tack for all of his help steering me the right way on this!
