I am looking for an RGB adapter which connects my be quiet Pure Base 500DX case with the ASUS TUF Z390-Pro gaming motherboard. Unfortunately, after buying it, I noticed that the RGB connector coming out of the front panel is a 3 pin. On the motherboard, I only have the option of connecting a 4-pin connector. Since I can't really see what the rectangular connector looks like in the pictures shown here, I'll ask around. Can anyone tell me if this adapter can help me ? Thanks in advance
