Alright, so I've connected my Radeon RX460 through a pci e express 1x to 16x riser card USB and I'm having trouble getting it to even work. I have Windows 7 and am using a Supermicro X7DVL-3 motherboard.

Hi ralphmanlap. Is there a reason why you are using a USB riser card instead of plugging your GPU directly into your motherboards PCI-E slot?
What is the model of the riser card?

Is this being plugged in correctly? I have a feeling it isn't. The only way for me to flip it around is if I cut off the hook or something.
The adapter is correct. Make sure all settings are correct and the power is sufficient. If the GPU is not getting enough power then it won't work and I assure you that AMD card is a power hog. As for setup, I have no knowledge of the software you are using. If this were a video issue then I could help but this is a non standard use. 
Ok that is more than enough for your setup.
Does the system power on using the external video card riser or what exactly happens when you have the riser card installed? Have you verified that the video card works in your motherboards regular PCI-E slot and that the computer boots or is that something that isn't possible to check?

Unfortunately, I am unable to check that because the only PCI-E slot on the motherboard is an x8. When I plug everything in, everything starts up except for the video card.
Have you verified that the video card works in another PC? If so and since your power supply has enough wattage to handle that video card, then your motherboard may not be able to run a newer video card such as the RX 460 without using that USB riser card.
Try plugging the riser card into another motherboard PCI slot and see if that works.
