ROG Enthusiast 3-way SLI Bridge Layout

The top cover of the ROG 3-way SLI Bridge is of an aluminum construction for rigidity with a dark brushed aluminum base and an ROG logo embedded in its center. The ROG logo glows red when powered.

The bottom of the ROG 3-way SLI Bridge resembles a typical 3-way hard NVIDIA-style bridge adapter with 3 sets of SLI bridge connectors. Each set of connectors is spaced to fit cards that are two slots apart. The bottom PCB is held to the top cover via two screws through the PCB.

ASUS also includes an external power cable to illuminate the ROG logo in the case where your cards cannot directly power the SLI bridge LED via the bridge ports. One end plugs into a MOLEX cable from your PSU and the other plugs into a two-pin power port located on the inside of the bridge assembly. The cable is sleeved with black sleeving material to blend in better to the background of your case and board.

SLI Bridge Design

After removing the screws holding the bottom PCB to the top cover, the bridge assembly easily separates into its component parts. The PCB and top plate are connected by a thin power cable for powering the LED in the cover via the PCB bridge connectors. The cable is removable from both parts as well. The LED module for the top plate is held in place via four screws at each of its corners.

With the LED plate removed, the inner side of the top plate is exposed. Upon inspection, you can see that the LED itself is not red. Rather, ASUS embedded a red filter in between the ROG logo cut into the top cover and the LED module.

The LED module is a simple assembly with the illuminated LED portion facing upwards toward the top cover when mounted to the cover plate. The bottom of the LED module contains several small power circuits in close proximity to the 2-pin power connector. The power cable from the bridge PCB plugs into this connector to power the LED.

The top of the bottom PCB resembles a typical NVIDIA-style hard bridge adapter with several additions. The PCB contains two power ports and power circuitry for powering the LED embedded in the top cover.

The top of the bottom PCB contains two power ports, one for connecting to the LED module in the top panel (labeled ROG) and one for connecting to the external power adapter (labeled EXT). To use the external power adapter, you simply plug in the two-pin connector into the EXT power port and thread the cable through the provided hole to the lower left of the ROG power port.
