The motherboard shortlist

The best motherboard for gaming in the UK is the MSI MAG B850 Tomahawk Max WiFi, at £229.99 on Amazon UK at the time of writing (September 2026), with a 14+2+1 power design on 80 A stages, four M.2 slots (two at PCIe 5.0), 5 GbE and Wi-Fi 7. The ASUS TUF Gaming B850-Plus WiFi at £189.00 is the value pick, and the ASUS TUF Gaming Z890-Plus WiFiat £199.99 is the board for Intel's Core Ultra 200S Plus chips.

Compare Electronic compared eight boards across AM5, LGA1851 and DDR4 platforms and priced what each step up the range adds. B850 is the chipset for most gaming builds in 2026: the ASUS ROG Strix X870-F Gaming WiFi costs £104.00 more than the B850 Tomahawk Max, adds two USB4 ports and gives up 5 GbE and two SATA ports.

What is the best motherboard for gaming in 2026?

The best motherboard for gaming in 2026 is an AM5 B850 board with 80 A power stages, a PCIe 5.0 graphics slot and at least one PCIe 5.0 M.2 slot, and the MSI MAG B850 Tomahawk Max WiFi is the best AM5 motherboard of that group at £229.99. The choice runs in three steps:

• Socket:AMD extended AM5 support "through 2029" at Computex 2026. Intel's LGA1851 is reportedly replaced by LGA1954 from early 2027, according to a leak.
• Chipset: B850 requires a PCIe 5.0 M.2 slot and allows CPU overclocking. X870 and X870E add mandatory USB4.
• Board: power stages, M.2 count, LAN and Wi-Fi separate boards on the same chipset.

The CPU sets most of the frame rate, so pick it first in the best CPU for gaming UK 2026 guide.

1. MSI MAG B850 Tomahawk Max WiFi - best motherboard for gaming

The MSI MAG B850 Tomahawk Max WiFi costs £229.99 on Amazon UK at the time of writing (September 2026). MSI specifies a 14+2+1 power design with 80 A smart power stages, a PCIe 5.0 x16 graphics slot, four M.2 slots (two at PCIe 5.0 x4), three rear 10 Gbps USB-C ports, Realtek 5 GbE and Wi-Fi 7.

Two PCIe 5.0 M.2 slots are the reason it leads. A PCIe 5.0 boot drive such as the Lexar NM1090 Pro 2TB, rated by Lexar at 14,000 MB/s reads, leaves a second full-speed Gen5 slot for a games drive. The Tomahawk Max suits buyers building around a Ryzen 7 9850X3D or 7800X3D who want every port a gaming PC uses without paying for X870.

Tom's Hardware's best ATX B850 pick (4 August 2026) is the newer MSI MAG B850 Tomahawk Max WiFi II, which adds an extra M.2 socket, OC Engine BCLK control and a 64 MB BIOS chip. Buyers who find the WiFi II at the same price should take it.

2. ASUS TUF Gaming B850-Plus WiFi - best value B850 motherboard

The ASUS TUF Gaming B850-Plus WiFi costs £189.00 on Amazon UK at the time of writing (September 2026), £40.99 less than the MSI MAG B850 Tomahawk Max WiFi. ASUS specifies the same 14+2+1 power design on 80 A DrMOS stages, a PCIe 5.0 x16 slot, three M.2 slots (one at PCIe 5.0), 2.5 GbE, Wi-Fi 7 and a rear 20 Gbps USB-C port.

The saving costs a PCIe 5.0 M.2 slot and half the LAN speed. ASUS notes that the chipset x16 (x4) slot is disabled when M.2_3 is in use, so a third SSD and a second expansion card cannot run together. The TUF B850-Plus suits a gaming PC with one graphics card and one or two SSDs.

3. Gigabyte B850 Aorus Elite WiFi7 - best budget B850 motherboard

The Gigabyte B850 Aorus Elite WiFi7 costs £172.99 on Amazon UK at the time of writing (September 2026), the cheapest B850 board in this guide. Gigabyte lists a digital twin 14+2+2 power design with 60 A DrMOS vcore stages, a PCIe 5.0 x16 slot, three M.2 slots (one PCIe 5.0), 2.5 GbE and Wi-Fi 7.

The 60 A stages are the trade-off: the ASUS TUF Gaming B850-Plus WiFi uses 80 A stages for £16.01 more. For an 8-core gaming chip rated at 120 W by AMD, 14 phases of 60 A stages leave headroom; buyers planning a 16-core Ryzen 9 should step up to 80 A. The Aorus Elite suits buyers who want Wi-Fi 7 and PCIe 5.0 at the lowest B850 price in this guide.

4. ASUS TUF Gaming Z890-Plus WiFi - best motherboard for Intel

The ASUS TUF Gaming Z890-Plus WiFi costs £199.99 on Amazon UK at the time of writing (September 2026). ASUS lists a 16+1+2+1 power design with 80 A DrMOS stages, four M.2 slots (one at PCIe 5.0), a rear Thunderbolt 4 port, a 20 Gbps USB-C port, Intel 2.5 GbE, Wi-Fi 7 and CUDIMM memory support.

Z890 is the only Intel 800-series chipset that unlocks CPU overclocking, the point of a K-series chip such as the Core Ultra 7 270K Plus. The weakness is the socket: Tom's Hardware reported on 3 September 2026 a leaked schedule that moves Intel's next desktop chips, Nova Lake, to LGA1954, with the first CPUs reportedly in the first quarter of 2027. Intel has not announced it. The TUF Z890-Plus suits buyers who want Intel now and accept that the board will probably only host Arrow Lake chips.

What does the extra money buy on a gaming motherboard?

Each step from £151.45 to £333.99 buys one or two concrete features, and the best-value step is the £21.54 from the MSI PRO B650M-A WiFi to the Gigabyte B850 Aorus Elite WiFi7: PCIe 5.0 graphics and M.2 slots, a third M.2 slot and Wi-Fi 7. Each row shows what the board adds over the one above it.

• Whole ladder: £182.54 separates the bottom board from the top (£333.99 minus £151.45). The first three steps total £78.54 (£21.54 plus £16.01 plus £40.99) and cover every feature a single-GPU gaming PC uses.
• Price per M.2 slot: the Tomahawk Max costs the least per slot (£57.50), ahead of the Gigabyte (£57.66) and the ASUS TUF (£63.00). The MSI PRO B650M-A WiFi is the cheapest board but, with two slots, costs £75.73 per slot.
• The X870 step buys USB4: the ASUS ROG Strix X870-F Gaming WiFi adds two rear USB4 40 Gbps ports for £104.00 and keeps four M.2 slots with two at PCIe 5.0, but drops to 2.5 GbE and two SATA ports. Dearer X870E boards add a third PCIe 5.0 M.2 slot.

How do the gaming motherboards compare on paper?

On paper, the MSI MAG B850 Tomahawk Max WiFi matches the ASUS ROG Strix X870-F Gaming WiFi on M.2 slots (four, two at PCIe 5.0) for £104.00 less, and beats it on LAN (5 GbE against 2.5 GbE) and SATA ports (four against two).

B850 or X870: which should gamers buy?

Gamers should buy B850. AMD's chipset table shows that X870 mainly adds mandatory USB4 and a guaranteed PCIe 5.0 graphics slot, and every B850 board in this guide already wires its graphics slot at PCIe 5.0.

• AMD's figures are the minimum. B850 guarantees four PCIe 5.0 lanes for one M.2 slot; board makers can wire more, as the Tomahawk Max shows.
• B840 and A620 lock the CPU: no CPU overclocking and no PCIe 5.0 lanes. AMD EXPO memory profiles work on every AM5 chipset.
• Price ranges overlap. The MSI X870E Gaming Plus WiFi at £189.98 costs 98p more than the ASUS TUF Gaming B850-Plus WiFi, so compare power stages, M.2 slots and LAN, not the chipset letter.
• USB4 is the X870 case: 40 Gbps external drives and docks. For gaming alone, the £104.00 step from the Tomahawk Max to the ROG Strix X870-F buys nothing a game uses.

The USB4 pick: ASUS ROG Strix X870-F Gaming WiFi

The ASUS ROG Strix X870-F Gaming WiFi is the X870 board to buy for USB4, at £333.99 on Amazon UK at the time of writing (September 2026), with two rear USB4 40 Gbps ports and four M.2 slots (two at PCIe 5.0 x4). ASUS lists only two SATA ports and Intel 2.5 GbE, so builds with several 2.5-inch drives suit a B850 board better.

Is B650 still worth it against B850?

B650 is worth it only for a Micro-ATX build or at a clear discount: the Gigabyte B850 Aorus Elite WiFi7 costs £21.54 more than the MSI PRO B650M-A WiFi and adds a PCIe 5.0 graphics slot, a PCIe 5.0 M.2 slot, a third M.2 slot and Wi-Fi 7. B850 makes a PCIe 5.0 M.2 slot mandatory; on B650 it is optional, and the graphics slot stays at PCIe 4.0 unless the board is a B650E.

• MSI PRO B650M-A WiFi, £151.45: a PCIe 4.0 x16 slot, two PCIe 4.0 x4 M.2 slots, 2.5 GbE and Wi-Fi 6E on a 24.4 x 24.4 cm Micro-ATX board, per MSI.
• UK range: B650 and B650E boards run from £109.99 to £158.99 on Amazon UK, overlapping entry B850 boards from £105.00.

For gaming alone, B650 loses less than the spec sheet suggests. A PCIe 5.0 SSD such as the Lexar NM1090 Pro 2TB (£309.99) runs at PCIe 4.0 speed in a B650M-A slot, and TechSpot's SSD load-time test found that "it generally does not matter whether it is PCIe 3.0, 4.0, or 5.0". The best NVMe SSD for gaming UK 2026 guide matches drives to slots.

Which motherboard for a Ryzen 7 9850X3D or 9800X3D?

The MSI MAG B850 Tomahawk Max WiFi is the best motherboard for a Ryzen 7 9850X3D or 9800X3D, and neither chip needs an X870 or X870E board. AMD rates both 8-core chips at 120 W. TechSpot measured the 9850X3D at 162 W average EPS power, 27% more than the 9800X3D's 128 W, and every ATX B850 and X870 board in this guide runs a 14-phase vcore design or larger.

• Ryzen 7 9850X3D, £382.99: scores 100% in Tom's Hardware's 1080p CPU hierarchy (26 August 2026), against 97.0% for the Ryzen 7 9800X3D. With the Tomahawk Max, board and CPU cost £612.98.
• Ryzen 7 7800X3D, £299.00: scores 85.6%. With the Gigabyte B850 Aorus Elite WiFi7, board and CPU cost £471.99.
• Ryzen 5 7500X3D, £229.00: TechSpot measured it 11% slower than the 7800X3D. With the MSI PRO B650M-A WiFi, board and CPU cost £380.45; check the board's CPU support list for the BIOS version first.
• Memory:AMD tests its X3D chips with 32 GB of DDR5-6000, and TechSpot's AM5 bench runs DDR5-6000 CL30. The Patriot Viper Venom DDR5-6000 CL30 32 GB kit costs £429.99, more than any board in this guide, including the £333.99 ROG Strix X870-F.

Extra power stages matter more for 16-core chips such as the Ryzen 9 9950X3D, which AMD rates at 170 W, than for an 8-core X3D chip.

What is the best motherboard for Intel Core Ultra 200S Plus?

The ASUS TUF Gaming Z890-Plus WiFi at £199.99 is the best motherboard for the Core Ultra 7 270K Plus and Core Ultra 5 250K Plus, because Z890 is the only Intel 800-series chipset that unlocks CPU overclocking.

• Z890 costs less than the best B860.Tom's Hardware names the MSI MAG B860 Tomahawk WiFi its best B860 board. At £210.96 on Amazon UK, it costs £10.97 more than the TUF Gaming Z890-Plus WiFi.
• CPU: the Core Ultra 7 270K Plus costs £293.97 and scores 77.5% in Tom's Hardware's 1080p hierarchy, against 85.6% for the Ryzen 7 7800X3D.
• Memory: TechSpot lists an official DDR5-7200 rating for the 200S Plus chips, and LGA1851 boards are DDR5 only.
• Socket life:Nova Lake on LGA1954 is a leak, not an Intel announcement, but Tom's Hardware reports that Z990 boards have been shown. An LGA1851 board is a finished platform, not an upgrade path.

Do Ryzen 9000 CPUs need a BIOS update?

On a B650 or X670 board, possibly: AMD states that "a BIOS update may be required for Ryzen 8000 and 9000 series processors on 600 series boards", and older boards are more likely to need one. A newer chip such as the Ryzen 7 9850X3D can also need a newer BIOS than an 800-series board shipped with, so the board's CPU support list is the check to make before ordering.

BIOS flashback updates the firmware from a USB stick with no CPU or memory fitted, and every AM5 and LGA1851 board in this guide has it:

• ASUS BIOS FlashBack: TUF Gaming B850-Plus WiFi, ROG Strix X870-F Gaming WiFi and TUF Gaming Z890-Plus WiFi.
• MSI Flash BIOS Button: MAG B850 Tomahawk Max WiFi and PRO B650M-A WiFi.
• Gigabyte Q-Flash Plus: B850 Aorus Elite WiFi7.

Update the BIOS first, then switch on AMD EXPO: Zen 5's official memory rating is DDR5-5600, so a DDR5-6000 kit reaches its rated speed only with its EXPO profile enabled.

Does a gaming motherboard affect fps?

Rarely: frame rate comes from the CPU, graphics card and memory, and a motherboard's job is to feed them without holding them back.

• Power delivery:the Ryzen 7 9850X3D averages 162 W in TechSpot's measurement, well inside what 14-phase boards are built for.
• Storage: TechSpot found load times barely move between PCIe 3.0, 4.0 and 5.0 SSDs, so extra Gen5 M.2 slots add capacity, not frames.
• Memory speed: the AM5 boards here are rated for DDR5-7200 to DDR5-8400 overclocked, well above the DDR5-6000 that AMD and TechSpot test with.
• Memory type is the exception:Tom's Hardware measured an 11 to 14% average gaming loss with DDR4 against DDR5 on LGA1700 CPUs (28 July 2026), and up to 25% in some games.
• Overspending: How-To Geek lists overspending on the motherboard among the five most common PC-building mistakes.

The £104.00 between the Tomahawk Max and the ROG Strix X870-F goes further on a card from the best graphics card UK 2026 guide.

DDR4 boards: is AM4 or LGA1700 still worth it?

Yes, for tight budgets: 32 GB of Corsair Vengeance LPX DDR4-3200 costs £209.99 on Amazon UK at the time of writing (September 2026), £220.00 less than the £429.99 Patriot Viper Venom DDR5-6000 CL30 kit.

• LGA1700 saves £361.49 against the budget AM5 build (£810.44 minus £448.95), but costs fps. The MSI PRO B760M-P DDR4 (£89.99) takes 12th to 14th gen Core chips, the 11 to 14% DDR4 penalty applies, and a 14th gen chip should run microcode 0x12F or later.
• AM5 undercuts LGA1851.The B850 and Ryzen 7 7800X3D build costs £21.97 less than the Z890 and Core Ultra 7 270K Plus build (£923.95 minus £901.98) and scores 85.6% against 77.5% in Tom's Hardware's hierarchy.
• AM4 suits owners of a Ryzen 5000 chip. The Gigabyte B550 Eagle WiFi6costs £88.99 and takes DDR4-3200. Tom's Hardware judged AMD's 2026 10th Anniversary Edition of the Ryzen 7 5800X3D $70 to $100 too expensive for anyone without an AM4 board already.
• Rumoured: Intel is reportedly planning an LGA1700 refresh with DDR4 support in 2027. Intel has not confirmed it.

Why DDR5 costs this much is covered in the 2026 RAM shortage explained; owners of an AM4 or LGA1700 PC should read how to upgrade an old gaming PC first.

Who should skip these boards, and what should UK buyers check?

Owners of a working B650 or X670 board should skip a new motherboard entirely: a BIOS update is the cheaper route to a Ryzen 9000 chip.

• Non-overclockers on one SSD: a B840 board from £89.99 or an A620 board from £69.95 runs a six-core Ryzen 5 chip, with no CPU overclocking and no PCIe 5.0 lanes.
• Small cases:the four ranked boards are ATX. The MSI PRO B650M-A WiFi is the Micro-ATX option here; Tom's Hardware's best Mini-ITX B850 is the ASRock B850I Lightning WiFi.
• Buyers who would rather not build: the build vs buy a gaming PC UK 2026 guide prices both routes.
• Warranty and rights:MSI's UK policy covers motherboards for 36 months. The Consumer Rights Act 2015 gives a 30-day right to reject a faulty board for a full refund.
• Wi-Fi 7 needs a Wi-Fi 7 router to reach Wi-Fi 7 speeds.

Verdict

The MSI MAG B850 Tomahawk Max WiFi at £229.99 is the best motherboard for gaming in the UK: two PCIe 5.0 M.2 slots, 5 GbE, Wi-Fi 7 and a 14+2+1 80 A power design on the AM5 platform AMD supports through 2029. The ASUS TUF Gaming B850-Plus WiFi at £189.00 keeps the same power design for £40.99 less, and the Gigabyte B850 Aorus Elite WiFi7 at £172.99 is the budget B850 pick. Intel buyers should take the ASUS TUF Gaming Z890-Plus WiFi at £199.99, and buyers who need USB4 should step up to the ASUS ROG Strix X870-F Gaming WiFi at £333.99.
