Compatibility Notes
Socket, memory, power, and case fit should be verified against retailer specifications before purchase.
Upgrade Path
The AM5 platform offers a direct drop-in upgrade path to future Zen architecture processors without needing a motherboard replacement. Storage can easily be expanded via the secondary M.2 NVMe slot on the rear of the ASUS ROG Strix B650E-I motherboard, while the 64GB DDR5 memory configuration provides substantial overhead for heavy video rendering before requiring higher density kit swaps.
Tradeoffs
To fit a flagship RTX 5080 and 12-core Ryzen 9 processor under the $2500 cap within a Mini-ITX chassis, motherboard expansion is limited to two DIMM slots and a single PCIe slot. A 240mm liquid cooler was selected to maintain strict top-mount radiator clearance inside the NR200P V2, which requires aggressive fan profiles during prolonged all-core rendering workloads.
