When we were shown Vega at CES back in January, AMD was very careful to not really show the card at all. Well it looks like AMD was showing Vega in all its glory at the Ryzen announcement event. This system is running an AMD Ryzen 7-1800X and an AMD Radeon Vega 10 graphics card. This reveals to us the look of the reference card and the power connectors.
As you can see the reference Radeon Vega 10 graphics card is air-cooled and draws power from a combination of 8-pin and 6-pin PCI-Express power connectors. For reference NVIDIA’s reference GeForce GTX 1080 uses a single 8-pin PCI-Express power connector and the Titan X Pascal uses the 8-pin and 6-pin combination.
You can notice red LEDs near the power input, AMD’s R9 Fury X has something like this as well. In that case the LEDs are used to indicate faulty power draw or power input. In the image only the section of LEDs over one connector is lit up, maybe this is to indicate that the card is drawing power from only one connector?
