HI FRIENDS !
Can I connect many RGB fans or RGB fan's RGB cables or RGB strips using splitter cable directly from mother board without using any wired controllers or adapters?

Usually you can connect the LED cables with splitters or in series to your motherboard. The maximum power (voltage and amperage) the header supplies (either 4-pin RGB or 3 pin A-RGB) is listed in your manual. My X570 Pro4 can support 3A @ 12V for the AMD Fan LED Header, 3A @ 12V for the 4-pin RGB and 3A @ 5V for the adressable RGB header. And then you have to calculate how much power the lights use. With RGB fans my guess is (I don't use RGB stuff) that the power draw is somewhere listed in the manual or on the website from the manufacturer or retailer. With LED strips, it should be the same. If there is no indication anywhere, assuming 20mA per LED is a safe bet, as going above that is not advisable for most normal LEDs. And since RGB has 3 LED in one package (5050 package is pretty common I think) it is 60mA per "identifiable light" you can see. :) Hope that helps.

Define "many". If your motherboard does not already have a header for RGB devices, I would advise against this. You don't want to risk demanding too much current through the motherboard. I recommend you connect directly to the PSU.

I would only connect one fan per header. If you want to add more, I recommend using a fan controller that gets its power through a direct power connection from the PSU.

How can I extent my RGB header to work MSI mystic light? is cooler master RGB or ARGB controllers compatible to MSI mystic light?
