Down and dirty with the Asus GeForce RTX 2080 DUAL OC 8GB, it is solid and mostly heatsink. It is a 2.7-Slot Design, with a couple fans with 0dB Technology and IP5X dust resistance seals , which is a nice touch.
The fans have 4 pin connectors for power and management. Power Connectors 1x 6-pin + 1x 8-pin, with the 6-pin permenetly blanked off. It’s a PCIe 3.0 x16 Gen card, most likely one of the last from Nvidia.
