What's the difference between B650 and X670?

Both are AM5 chipsets. X670 has more PCIe lanes, more USB ports and often more M.2 slots. For gaming, a B650 board gives you the same performance.

Do I need a BIOS update?

Sometimes. A board from an earlier production run only recognises a newer processor after a BIOS update. Some boards can do this without a processor via BIOS Flashback; the manual explains how.

Does a micro-ATX board fit an ATX case?

Yes. An ATX case has mounting points for ATX, micro-ATX and mini-ITX. An ATX board won't fit a case that only supports micro-ATX, though.

Q: Which motherboard fits my processor?

One with the same socket: AM5 for a Ryzen 7000 or 9000, LGA1700 for Intel Core 12th to 14th gen and LGA1851 for Core Ultra 200S. Also check the board's CPU support list.

The motherboard connects every part of your PC and decides which processor, which memory and how many SSDs you can use. At COZO you'll find boards for AMD AM4 and AM5 and for Intel LGA1700 and LGA1851, in ATX, micro-ATX and mini-ITX, from ASUS, Gigabyte, MSI, ASRock and other brands. Filter on the left by socket, memory type and form factor to find the right board quickly.

Start with the socket and chipset

The socket must match your processor: AM5 for Ryzen 7000 to 9000, AM4 for older Ryzen, LGA1700 for Intel Core 12th to 14th gen and LGA1851 for Core Ultra 200S. The chipset then decides what the board can do.

AMD AM5: A620 (entry), B650 and B850 (the sweet spot), X670 and X870 (more connectivity and M.2 slots, X870 always with USB4).
Intel LGA1700: H610 (entry), B760 (mid-range), Z790 (overclocking K processors).
Intel LGA1851: B860 for most builds, Z890 if you want to overclock.
