Best-value LGA1851 motherboards under £300 right now

The LGA1851 motherboards under £300 in stock on Amazon.co.uk, best value first. This list is generated from price, popularity and the specifications each Amazon listing states, not from hands-on testing.

This budget covers the whole B860 range and the entry Z890 boards, the only LGA1851 chipset with CPU overclocking. Thunderbolt 4, WiFi 7 and several M.2 slots, at least one of them PCIe 5.0, are common at this level. For a Core Ultra 5 or 7 run at stock settings, a good B860 board does the same job.

Tick two to four boards, then compare them side by side.

How this list is made

Nobody at motherboarddeals.co.uk has tested these boards. The list is generated from the data we hold: the price on Amazon.co.uk, how well the board sells, and the specifications its Amazon listing states. A board has to be in stock and under the budget to appear. It then scores points for being in stock (10), for its Amazon sales rank (up to 30, on a sliding scale), for selling below its own usual price of the last 90 days (one point per percent, up to 20, once we hold two weeks of its price history), for the features its listing states (up to 30: WiFi generation, 2.5 GbE or faster networking, the number of M.2 slots, PCIe 5.0 and a BIOS flashback button) and for how recently it was first available (up to 10). The line under each board names the factors that counted for it. A feature the listing does not state scores nothing, so a good board with a thin listing can rank lower than it deserves, and CPU and board bundles are left out. The order is recalculated whenever prices are checked, roughly every six hours; nobody can pay to move up it. How we track motherboard prices explains where the numbers come from.
