The cheapest compatible motherboard for your CPU and RAM
Cheapest compatible board picks start with socket and RAM type. ASRock’s DDR4 and D5 H610M-HDV boards share a name but take different memory.

Front Panel Header Wiring: MSI, ASUS, ASRock, Gigabyte
On a ten-position front panel header, leave pin 9 empty: Intel’s layout uses it for power. Also covered: 3-pin power LED plugs and keyed USB headers.
RAM slot order for dual channel on a 4-slot board
Dual channel slot order splits on one stick: ASUS, MSI and ASRock use A2, while Gigabyte’s Z790 AORUS PRO X manual accepts A2 or B2.
How many M.2 slots can you use at once without losing ports
None of these nine boards lists a SATA port lost to an NVMe drive. An extra M.2 drive costs a PCIe slot, USB4 lanes or graphics lanes instead.
Motherboard power connectors and which PSU cable fills each one
Motherboard power sockets on MSI’s MAG X870 Tomahawk WiFi include PCIE_PWR1, a third 8-pin wired like a PCIe plug, so a CPU cable doesn’t belong there.
Motherboard form factor case fit, from Mini-ITX to E-ATX
Motherboard sizes nest because six of nine micro-ATX screw holes sit on ATX positions, per Intel’s spec. Back-connect boards need a case cut for them.
CPU cooler socket compatibility, case height and RAM gap
CPU cooler mounts carry over from LGA1700 to LGA1851 and, with the stock backplate, AM4 to AM5. Then your case limit and RAM height decide the fit.
GPU motherboard compatibility and what sits around the x16 slot
GPU and motherboard fit on micro-ATX depends on slot position. One slot down, a 62.5 mm card runs 1.54 mm past the board’s fourth position.
Motherboard compatibility: socket, BIOS, slots and fit
For motherboard compatibility, ASUS lists the Ryzen 7 9700X as validated since BIOS “all” on the TUF B650-PLUS WIFI and since 2613 on its micro-ATX sister.
