What motherboard suits Core i9 13900TE, and how should power delivery, memory, and ports be balanced?

  The 13900TE uses LGA1700, but unlike a regular desktop i9, board support isn't guaranteed. It's an embedded SKU, so the safest bet is a Q670 or industrial board whose CPU list explicitly names the TE part. Some consumer H610/B760 boards will boot it, but their BIOS may not officially recognize it—confirm with the seller first. Memory follows the board: DDR4 or DDR5, pick one. If you're building an always-on appliance, Q670 is the right call for its VRMs, multi-NIC, and serial ports. If you just wanted a normal desktop, a 13700 would be the simpler choice.
