Do you have sufficient PCIe lanes available?

I'm building my own PC, and I ran into an issue which I think might have to do with PCIe lane availability. My build is as follows: CPU: AMD Ryzen 7 3700x MB: MSI x570-A Pro GPU1: AMD Radeon Pro W5500 Workstation GPU GPU2: AMD Radeon RX 5700 XT Desktop CPU WD Black 1TB M.2 NVME SSD 4x Seagate Barracuda SATA HDD (probably gonna run in RAID 10) ASUS Intel Wifi/Bluetooth PCIe x1 Expansion Card Repurposed SATA ODD Edit 1: 4x 16GB Corsair Vengeance LPX DDR4 3200MHz DIMM Will I have enough PCIe lanes to run everything? If not, are there any solutions that don't involve sacrificing any of the parts? Edit 2: Update – It all works now, turns out all I needed was a BIOS update Edited June 20, 2020 by williamli9300 Update

The CPU provides 24 lanes while the X570 adds another 16.

They’re asking if the setup will suffice. With 24 GPUs, 5 lanes for SSD and Wi-Fi, plus SATA, USB controllers, and RAM, PCIe lanes are likely involved. They want to know the exact amount.

Choose a superior motherboard capable of handling x8/x8 lanes.

The number mentioned was negative, reflecting disappointment over the lack of a prem selling feature.

It added extra cost or made it permanent since AMD confirmed B550 would support it, eliminating the need for users to purchase a more costly board. Not every B550 model runs at x8/x8 lanes, while others continue using x16/x4 configurations.

Ryzen offers 24 lanes whereas Intel provides fewer. Ensure your slots support this, such as a 16x configuration that also features electronic communication.

AMD offers the same functionality, but they both charge a higher price for those who wish to access it. The current situation might have slightly increased costs. Prior to this, you could locate a board for roughly $150 or less.
