I'm looking for recommendations on the best power supply and motherboard to support an RX 9070 XT and the upcoming 5080 Super. I want to ensure that the second GPU slot can run at full speed and provide sufficient power for both cards. Any advice?

For a solid dual GPU setup, I recommend the ASUS ProArt motherboard. It can accommodate two 2.5-slot cards without needing risers, which is pretty convenient. Just make sure to check out the pinned posts in the associated forums because there's a comprehensive list of compatible models. If you're planning to use a larger 3+ slot 5080 Super and want to install the 9070 XT vertically, you might want to consider different options. A 1000W PSU should cover you well for both GPUs.
Honestly, mainstream motherboards and CPUs typically don't support full-speed secondary PCIe slots. Most only have 20-24 PCIe lanes available, which limits the performance of dual setups. So while you can run your GPUs, they won't be utilizing their full potential in some configurations.
