I'm building a system in the USA with a Ryzen 9 7900X, RTX 5080, and DDR5 memory. I need a white AM5 motherboard that can run an Elgato 4K60 Pro MK2 and an Elgato HD60 Pro internal capture card at the same time, while also supporting three 4TB M.2 SSDs. Ideally, I'd like to stay under $300, but I'm willing to consider slightly more expensive options if necessary. Will these components work together without problematic PCIe lane sharing?

The MSI MPG B850 EDGE TI WIFI looks like a strong match and costs roughly $280 in the USA, depending on the retailer. Its white design also fits the aesthetic requirement. Before buying, verify the motherboard’s PCIe slot and M.2 lane layout to make sure both capture cards and all three SSDs can operate together.
The Elgato 4K60 Pro MK2 needs at least a PCIe 2.0 x4 connection, while the HD60 Pro needs PCIe 2.0 x1. For the SSDs, you’ll probably want three PCIe 4.0 x4 M.2 slots. The non-white MSI MAG B850 Gaming Plus Max WIFI is around $200 and covers nearly everything, but its third M.2 slot is limited to PCIe x2. That usually has little noticeable impact, but it is technically slower. The white MSI MAG X870E Gaming Plus Max WIFI is a better fit and has been available around $259, making it the safer choice for your requirements.
I already own an MSI MAG X870E motherboard. I’m checking whether that model’s specific slot and lane configuration will handle the two capture cards and three M.2 drives together.
Does it support both capture cards and all three SSDs simultaneously, or are there any lane-sharing limitations?
