I'm currently using a B450M DS3H motherboard with a Ryzen 7 1700X and a Radeon RX 570, powered by a 600W PSU. I just bought a GTX 1660 Super to replace the RX 570, but I remembered that some people were able to run dual GPUs. I'm curious if it's possible to install and utilize both of these graphics cards, even if just for virtual machine purposes, since I sometimes need to boot into Windows for After Effects. My specific questions are: 1) Can I run two different GPUs on this motherboard? 2) How do I physically install both? 3) Is my 600W PSU enough to power them both? Thank you for any insights!

If you’re not looking to game with both GPUs, using them together for any purpose, including virtual machines, should be fine. Just remember, if both cards are drawing maximum power, your 600W PSU may not suffice, especially if you factor in all other components. It's wise to calculate the total power draw before you proceed.
Yes, you can install both GPUs on the B450M DS3H motherboard. Just ensure you have enough space in your case and keep an eye on your power supply's capacity. If space is tight, consider using a PCI-E riser cable to reposition one of the cards. Don’t forget to check your motherboard manual for any limitations on dual GPUs since the second PCI-E slot might not offer full bandwidth, which can affect performance a bit.
