WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

ASUS PRIME B860M-K

What it brings

A PCIe 5.0 x4 M.2 slot plus a second PCIe 4.0 x4 M.2 slot and four SATA ports give several storage options for a small board.
Manufacturer source
Rated for DDR5 up to 8800+ MT/s (OC) with CUDIMM support, plus 2.5 Gb wired Ethernet and a front USB Type-C connector.
Manufacturer source

What to check

Only two DIMM slots (128 GB maximum), so a later capacity upgrade may mean replacing both modules.
Manufacturer source
The graphics slot is PCIe 4.0 rather than PCIe 5.0, there is no rear USB-C port and ASUS lists no Wi-Fi.
Manufacturer source

ASUS TUF GAMING B860M-PLUS

What it brings

3 M.2 storage positions and 4 SATA connectors provide several drive-connection options.
Manufacturer source
1 × Realtek 2.5Gb Ethernet provides a wired network connection.
Manufacturer source

What to check

M.2_1 supports PCIe 5.0 x4; M.2_2 and M.2_3 support PCIe 4.0 x4. The listed Intel RAID support is for SATA storage.
Manufacturer source
Check the exact processor, BIOS and memory kit before purchase. The 256 GB ceiling and listed overclocking profiles are configuration limits, not a tested build guarantee.
Manufacturer source
The inspected specification does not verify an included wireless module; plan around the wired connection unless the exact retail configuration confirms one.
