asrock H470 phantom gaming 4

When I google this LED LED strip, it looks to be an RGB strip.
But I cannot see what voltage.
Yeah you already know that, but there is a difference in the way LED strips work, and it is important that you connect it to the correct header (connector) on the board
You gave 2 White headers, the are used for 12Volt RGB
And you have 2 Grey headers, the provide 5Volt RGB
Check the manual

Page 4, headers 7 and 8, and headers 27-28

On page 24, you see the pinout of the connectors
I assume your RGB strip is a 12Volt RGB, then you have to use the white headers, and on the LED strip, usually yu see a tiny arrow, telling which pin is pin 1.
On a RGB LED strip, all LED's have the same color.
When your LED strip is a 5Volt Addressable RGB, you must connect it to one of the Grey headers, here you se that it has 1 pin missing (key pin)
Addressable RGB can have different colors at the same time, so part of the RGB strip has a different color.
First find out if this is RGB or ARGB, and the voltage, then conenct iot to the correct header.
