[lockandchase]

Hello, I have the antec DP501 and the asus strix Z490A-Gaming, I dont know where to plug the cases rgb cable to. I tried plugging it onto the motherboard's rgb header, but its 4 pin and its so loose, why the cable only has 2 holes.
Please help me

Are you using the right cable?

I did some research and I dont need to use the vdg cable since I already have the 4 pin header thats missing 1 in the middle
