Crosshair x670e Extreme - Are the Gen 2 RGB headers 3amp for all 3 or for each?

Page 1-18 in the manual Says

"The Addressable Gen2 header supports WS2812B addressable RGB LED strips (5V/Data/Ground), with a maximum power rating of 3A (5V), and the addressable headers on this board can handle a combined maximum of 500 LEDs."

But there are two headers and one is a double 3 pin so in total 3 sets of (5V/Data/Ground) on the MB. I can't tell from this which of the following may be correct.

3A total
3A total with 1A per 3 pin set. So 1A for single and 1A each for double header pin sets.
3A each header(3A single header, 3A double header total)
3A each per 3 pin set(3A for single header and 3A each for the two pin sets in the double header)

I am guessing this one but I am not sure. "3A total with 1A per 3 pin set. So 1A for single and 1A each for double header pin sets."
But on the other hand the Aura header for the 12V RGB is 3A on the single 4 pin header.

Anyone know for sure the Amp max per 3 pin set? Thanks

Hello, decimus28.

According to the user manual, the B Gen2_12 port is for 6 pins; however, it is also able to be installed with two 3 pins.
The A and B ports each have a maximum power rating of 3A (5V).

Thank you.
