There are two types of RGB lighting systems. The plain RGB system uses a 4-pin mobo header that supplies a common 12 VDC pin and three separate Ground lines, one for each of the three LED colours (Red, Green, Blue). By manipulating the three Ground lines it can generate a huge range of colours. Along the strip ALL of the LED locations show the same colour, so the whole strip is one colour at any given moment.
The more complex Addressable RGB (ADDR RGB, ARGB, Digital RGB) uses a 3-pin header (looks like the 4-pin one with one pin missing) that contains common +5 VDC and Ground pins and a digital Control Line that carries addressed info packets. Along the strip the LED's all are in Nodes, with each Node containing one LED of each of 3 colours plus a control chip that listens to that Control Line. When it gets an instruction addressed to it, it does that display with its three LED's. Thus at any given moment all of the Nodes along the strip can be different colours, and you can see more complex displays like a rainbow that chases itself along the strip.
Because both the Voltage supply and the display control methods are so very different, you can NOT mix lights of the two different systems in one circuit on a header.
YOUR mobo has two header of EACH of these types. There is one of each type at top right, and one of each at bottom closer to the rear (See p. 15). the plain RGB ones are labelled LED_Cn, and the Addressable ones are labelled D_LEDn. It also has an uncommon feature to accommodate a version not very common any more: each D_LEDn header has an associated set of jumper pins labelled DLED_V_SWn. It has a jumper you must set to select the voltage jumper supply on the D_LEDn header, and this allows use of a (now rare) version of addressable RGB that did use 12 VDC. Set yours to the 5 VDC setting.
The headers on your mobo use a pin pattern that is now VERY widely used so many consider them "standard". Most commercial light strips (and fans that contain RGB or ARGB lighting in their frames) have this type of connector on them. However, some companies who got into this market early used different connectors on their units (even though, electrically, they all are the same) and have not changed. For these, it is common now that they may include with their lighting units an adapter cord to allow you to plug their "non-standard" lights into a "standard" mobo header. Keep an eye out for this when buying. MANY lighting "kits" designed for use with mobos that do NOT have any RGB headers include lights and a controller box and maybe a remote control unit, and the connectors on all of the system are non-standard so you can only use the parts in their system. Very often you can NOT connect these to a "standard' mobo header.
To help you recognize connectors, here is an extension cable for the plain RGB (4-pin) system
Note that it has female (with holes) connectors on both ends, and comes with a little gender-changer adapter to plug into ONE end to convert it to male.
Here is a corresponding one for a 3-pin ADDR RGB system.

See the difference?
NOTE that, on a 4-pin system, each connector has one end of it marked as the 12 VDC line (you can see that in the link above), and there is a similar mark on the pins of the mobo header. Because it is possible to plug it in either way around, YOU must be SURE to align the marks when you make any connection. On the 3-pin ADDR RGB system you cannot plug it in backwards because of the pin arrangement.
If you need more than two headers of one type to allow several lighting units, you can get plain RGB (4-pin) or ADDR RGB (3-pin) SPLITTERS that convert one header into two or more (up to five?) outputs. The limit here is that most mobo headers of this type can supply up to 3.0 A max load, so you need to know the max current required by the LIGHTS ONLY in whatever device you plan to plug in. (For example, in a "RGB Fan", the current for the fan MOTOR (which has its own separate power cable) is NOT part of the lighting load of that unit.)
