I just recently purchased an Aurora R10 with Ryzen 3500 and a RX 5700 video card.

I am curious if I can add a second GPU? I am not sure what power supply I have. The GPU does not need to SLI or CrossFireX.  I've read Alienware can have issues with heat as well. My unit is only air cooled.  I looked at the motherboard and it does appear to have an extra PCIe x16 slot (the RX 5700 is currently in the other one).
