Just need some help identifying these connectors
VDG stands for Voltage, Data, Ground. This connector is designed for addressable RGB on motherboards using a 3-pin header, while the adjacent 4-pin plug fits standard RGB headers. Your setup includes RGB fans and possibly a fan controller or RGB controller. The wide ribbon cables likely connect to fan controllers, with four wires carrying voltage, ground, RPM sensor, and PWM signal for speed control. The remaining four wires probably handle addressable RGB signals or regular RGB data (voltage, data, ground or voltage, plus color channels). There may also be detachable extensions for easy management. It’s recommended to trace the wires carefully to identify their functions before disconnecting any components.
previously no 4-pin addressable RGB MBD connector existed except Corsairs. If it does, it must be RGB. Edited August 9, 2025 by thrasher_565
Right-side 4-pin addressable RGB header available – includes one NC pin for convenience
Hey, you're asking a lot of questions! The motherboard header has four slots but one pin is missing, usually labeled KEY. The connector you're using is a four-pin plug with one missing female contact. It's designed so that regular users can't fit it into the other four slots (like 12V, red, green, blue). This prevents them from inserting the wrong plug and possibly harming the LEDs. The three-pin header (voltage, data, ground) is meant for correct use only—placing it wrong could damage the LED strips. Some boards with only 5V addressable RGB strips use just the three-pin header, which is why cases include it. The case shows only data and ground wires; the RGB controller or splitter is likely powered through a different connector like SATA or Molex.
The setup involves a kolink observatory with an existing fan hub and a RGB lighting system that can be controlled via either the reset button or software. For now, let’s stick to the simpler side—press the button. The two connectors connected are likely for software management, so no immediate plug-in needed. (Confirm?) There’s a large chain connecting all the fans, and off it there are two connectors; one clearly labeled SATA. There’s also a puzzling 4-pin connector, though inspecting the PSU makes me curious—does it fit there? If so, would I need both SATA and 4-pin, or just one? Also, a few PSU connections remain unused; as long as they don’t reach the motherboard, it should be fine. The clearer the images, the better.
It seems you're trying to set up the PSU correctly. Based on your description, you're connecting the PSU directly to the chassis, only wiring the necessary components like SATA and power cables. Make sure all connections are secure and nothing is touching the motherboard to avoid issues.
