Z890 is Intel’s enthusiast desktop chipset for LGA1851 Core Ultra processors. Its biggest reason to exist is not that it automatically makes games faster than B860. It is the 800-series option that gives you CPU, BCLK and memory overclocking together with Intel’s largest mainstream platform I/O and PCIe budget.
That makes Z890 a logical choice for unlocked Core Ultra builds where you actually intend to tune the processor, or for systems that need more storage, expansion cards and high-speed connectivity than a typical gaming PC.
If you plan to run the CPU at normal settings and need one GPU plus a few SSDs, B860 deserves serious consideration before you spend more.
The Z890 motherboards I would shortlist
MSI MAG Z890 TOMAHAWK WIFI II
The 2026 revision I would start with for a normal full-size Z890 build: strong storage, 5Gb networking, Thunderbolt and excellent debug features.
- 4 M.2 slots + PCIe 5.0 graphics and Gen5 storage
- 5GbE, Wi-Fi 7, Thunderbolt 4 and POST-code display
- Limitation: only one rear Thunderbolt 4 port
ASRock Z890 LiveMixer WiFi
Its reason to exist is the huge peripheral budget: an unusually good fit for streaming and creator desks covered in USB hardware.
- Dual Thunderbolt 4 plus extensive USB connectivity
- PCIe 5.0 graphics, 3 M.2 and Wi-Fi 7
- Limitation: 2.5GbE rather than 5GbE and only three M.2 slots
ASRock Z890M Riptide WiFi
The compact choice when you still want four DIMMs, three M.2 slots and dual Thunderbolt 4 rather than dropping all the way to Mini-ITX.
- Micro-ATX with 3 M.2 and 4 DIMM slots
- Dual Thunderbolt 4 + 2.5GbE
- Limitation: Wi-Fi 6E rather than Wi-Fi 7
MSI MPG Z890I EDGE TI WIFI
An unusually storage-rich Mini-ITX board with four M.2 positions, 5Gb networking and dual Thunderbolt 4.
- 4 M.2 slots in a Mini-ITX build
- 5GbE, Wi-Fi 7 and dual Thunderbolt 4
- Limitation: part of the storage and I/O depends on MSI’s expansion card

What changed with Intel Core Ultra 200S Plus?
Intel launched the Core Ultra 7 270K Plus and Core Ultra 5 250K/KF Plus in 2026, but you do not need a completely new chipset generation to use them.
Intel says the 200S Plus desktop processors remain compatible with existing 800-series motherboards. That means a Z890 board originally released for the 285K, 265K or 245K can also support the newer Plus processors, provided the motherboard has the required BIOS support.
The newer processors also increase official DDR5 support and introduce early support for 4-rank CUDIMM configurations on selected 800-series motherboards. The key word is selected: do not assume that every existing Z890 board supports every new high-capacity memory configuration.
Check the CPU support list and BIOS before installing a 200S Plus CPU
“Compatible with 800-series motherboards” does not mean every board shipped with the required firmware. Check the manufacturer’s CPU-support page and update the BIOS when necessary before troubleshooting anything else.
Do you actually need Z890, or is B860 enough?
This is the most important buying decision on the page.
Intel allows memory overclocking on both B860 and Z890. Z890’s major distinction is that it also enables IA/CPU and BCLK overclocking and gives motherboard designers a substantially larger high-speed I/O and PCIe budget.

| Feature | B860 | Z890 | Why it matters |
|---|---|---|---|
| CPU / IA overclocking | No | Yes | Required if manual CPU tuning is part of the build |
| BCLK overclocking | No | Yes | Additional enthusiast tuning control |
| Memory overclocking | Yes | Yes | You do not need Z890 simply to run XMP memory |
| Platform high-speed I/O lanes | Up to 45 | Up to 60 | More flexibility for storage and connectivity |
| Total platform PCIe lanes | Up to 34 | Up to 48 | Matters more in expansion-heavy builds |
| Typical fit | Stock-clock gaming / general builds | Tuning and high-expansion builds | Choose for the workload, not the badge |
Buy B860 if…
You plan to run the CPU at normal settings and mainly need one graphics card, a few NVMe SSDs, XMP memory and normal gaming connectivity.
An unlocked K-series processor can physically work on B860. What you give up is Intel’s CPU/BCLK overclocking support, not basic CPU compatibility or memory overclocking.
Buy Z890 if…
You intend to tune the CPU, need more PCIe and high-speed I/O flexibility, or are building a system with several storage and expansion devices.
Z890 is also easier to justify on high-end creator systems where Thunderbolt, multiple NVMe drives, networking and add-in cards all compete for platform resources.
An expensive Core Ultra CPU does not automatically require Z890
If your 270K Plus or 285K will run at normal settings with one GPU and two SSDs, the question is whether you need Z890’s tuning and expansion capabilities — not whether the processor is expensive enough to “deserve” the flagship chipset.
The four Z890 motherboards in detail
1. MSI MAG Z890 TOMAHAWK WIFI II
The WIFI II revision is the Z890 board I would use as the default comparison point in 2026. It is new enough to reflect MSI’s current Z890 lineup but does not make sense only for extreme overclockers.
Storage is straightforward: one CPU-connected PCIe 5.0 x4 M.2 position plus three additional Gen4 M.2 slots. Four SATA ports remain available for older SSDs and hard drives, so this is an easy board to recommend to someone carrying storage forward from an existing PC.
The main graphics slot is PCIe 5.0 x16, and MSI also provides two chipset-connected PCIe 4.0 x4-size expansion connections. That gives a full-size build much more flexibility than Mini-ITX and considerably more physical room than Micro-ATX.
Networking is one of its better practical features. MSI uses 5Gb Ethernet alongside Wi-Fi 7 rather than treating 2.5GbE as automatically sufficient on a higher-end motherboard.
Rear Thunderbolt 4 provides a 40Gbps connection for fast external hardware. The board also includes Flash BIOS, Clear CMOS, four EZ Debug LEDs and an EZ Digit Debug display. Those troubleshooting features are far more useful to an enthusiast than another decorative motherboard cover.
The compromise compared with some earlier or more expensive Z890 boards is that this revision provides one rear Thunderbolt 4 connection rather than two. If your workflow revolves around several Thunderbolt devices, that can make another board more attractive.
Buy it if: you want a full-size Z890 board with four M.2 slots, 5Gb networking and genuinely useful diagnostic features.
Skip it if: your workflow specifically requires multiple onboard Thunderbolt 4 ports.
2. ASRock Z890 LiveMixer WiFi
The LiveMixer earns its place through I/O rather than through a generic “premium” label.
ASRock explicitly designs the series around creators and streaming setups, and that makes sense when you look at the connectivity. The board includes dual Thunderbolt 4/USB4 Type-C connections and an unusually large number of USB 5Gbps connections across its rear panel and internal headers.
For a normal gaming PC that might be unnecessary. For a desk carrying cameras, capture devices, microphones, audio interfaces, controllers, lighting hardware and external storage, it can remove the need for several external USB hubs.
Expansion is also useful. You get a PCIe 5.0 x16 graphics connection plus additional physical PCIe slots for capture, networking or other add-in hardware.
Storage is a little less ambitious than the MSI’s raw count: one Gen5 M.2 plus two Gen4 M.2 positions. The wired network is also 2.5GbE rather than 5GbE.
Those limitations are why this isn’t simply ranked above or below the Tomahawk. Buy it because your USB and creator-device requirements make its design useful.
Buy it if: your streaming or creator setup genuinely uses a large number of external devices.
Skip it if: four M.2 positions or faster wired networking are more valuable to you than the extra peripheral connectivity.
3. ASRock Z890M Riptide WiFi
Micro-ATX makes sense when you want a smaller tower without accepting the largest compromises associated with Mini-ITX.
The Z890M Riptide keeps four DDR5 DIMM positions and gives you three onboard M.2 slots: one PCIe 5.0 position plus two Gen4 positions. Four SATA ports provide room for older storage as well.
The rear I/O is unusually capable for the format. ASRock includes two Thunderbolt 4/USB4 Type-C ports along with 20Gbps front Type-C support, 2.5Gb Ethernet and wireless networking.
The obvious 2026 compromise is the wireless module: it is Wi-Fi 6E rather than Wi-Fi 7. That sounds worse on the specification sheet, but it should matter only if you actually intend to use a Wi-Fi 7 network.
Physical expansion is the bigger reason to think carefully. Micro-ATX simply has less board area below a large modern graphics card. If your future plans include several capture, networking or storage add-in cards, choose ATX instead.
Buy it if: you want Z890 CPU tuning and strong connectivity in a smaller four-DIMM motherboard.
Skip it if: you need several add-in cards or Wi-Fi 7 is an important requirement.
4. MSI MPG Z890I EDGE TI WIFI
The Z890I Edge Ti is the most unusual main recommendation here because MSI manages to expose storage and networking normally associated with a much larger motherboard.
There are four M.2 positions in total: one CPU-connected Gen5 slot and three Gen4 positions. One of those M.2 positions, along with the board’s SATA connections and some front USB connectivity, is provided through MSI’s 5-in-1 expansion card.
That is both a strength and a limitation. It lets MSI fit far more connectivity into a Mini-ITX footprint, but it introduces an additional vertical daughterboard and makes the internal layout more complicated than a conventional ATX motherboard.
Rear connectivity is excellent for SFF: two Thunderbolt 4 ports, seven 10Gbps Type-A connections, another 10Gbps Type-C port, 5Gb Ethernet and Wi-Fi 7.
But Mini-ITX still means two DIMM slots and one primary PCIe expansion connection. Do not pay the small-form-factor premium if the system is going into a large case anyway.
Buy it if: you genuinely want a small Intel system but still need serious NVMe and network connectivity.
Skip it if: a normal Micro-ATX or ATX case fits your plans and you value simpler expansion.
What actually matters when choosing a Z890 motherboard
1. Decide whether CPU overclocking is actually part of the plan
This is the first question because CPU/BCLK tuning is one of the clearest reasons to choose Z890 over B860.
If you have no intention of adjusting CPU clocks and simply want XMP memory, B860 remains an option. Intel supports memory overclocking on B860 as well as Z890.
Do not spend more on the chipset merely because your CPU model ends in K. Spend more because you intend to use the feature.
2. Count the expansion devices before comparing VRMs
Z890 has a substantially larger platform I/O and PCIe budget than B860, which matters when you install many devices simultaneously.
List your graphics card, M.2 SSDs, capture cards, networking hardware, audio cards and other PCIe devices before choosing the motherboard.
For a one-GPU gaming machine with two NVMe drives, an enormous expansion layout is mostly unused potential.
3. Check M.2 count and PCIe lane sharing separately
Never stop at “this board has four M.2 slots.”
You also need to know which slots use CPU lanes, which run through the chipset and whether populating a particular M.2 connection reduces the bandwidth available to another PCIe slot.
These details become especially important on high-end systems because the buyer is more likely to populate most of the connectors.
4. Thunderbolt 4 matters only if your devices use it
Thunderbolt can be genuinely valuable for fast external storage, docks, professional interfaces and display workflows.
It adds very little to a gaming PC whose external devices consist of a keyboard, mouse and headset.
Count the devices you expect to attach before paying extra for multiple Thunderbolt connections.
5. Don’t buy by advertised DDR5 maximum
Motherboard memory specifications regularly advertise speeds far beyond what an ordinary gaming build will use.
Memory capability depends on the CPU, memory type, rank configuration, number of DIMMs and BIOS support. Four populated DIMM slots generally create a more difficult electrical load than two.
Treat enormous DDR5 OC figures as evidence of the board’s tuning ambitions, not as a speed you should automatically target.
6. Core Ultra 200S Plus makes memory compatibility more complicated
The 2026 Plus processors increase official memory support and introduce early support for very high-capacity 4-rank CUDIMM configurations on selected boards.
If you are planning an unusual high-capacity memory build, check the board’s current memory QVL and BIOS documentation rather than assuming “Z890” guarantees compatibility.
7. 5Gb Ethernet is not automatically better for your PC
The Tomahawk and MSI Mini-ITX board provide 5Gb Ethernet, which can be useful for fast NAS and workstation traffic.
If your router, switch and storage are all 1Gb or 2.5Gb devices, however, a 5Gb motherboard port does not magically make the rest of the network faster.
8. Build and diagnostic features are worth real money
BIOS Flashback, Clear CMOS, debug LEDs, POST-code displays, tool-free M.2 mechanisms and easier GPU-release systems can save far more time than many decorative motherboard features.
This matters particularly on Z890 because people buying an enthusiast chipset are more likely to tune memory, change BIOS settings and swap components later.
What I would avoid when buying Z890
Do not buy the most expensive Z890 because it has the biggest VRM
Power delivery matters, especially for sustained high-power workloads and CPU overclocking. But once a board comfortably handles the processor and settings you intend to use, an even larger phase count does not automatically increase gaming performance.
Spend the additional money only when the more expensive board gives you something the build will use: additional M.2 storage, networking, I/O, diagnostic tools or specialized overclocking hardware.
Other Z890 motherboards worth considering
GIGABYTE Z890 AORUS Elite WIFI7
A strong conventional ATX alternative with four M.2 positions, PCIe 5.0, Thunderbolt 4, Wi-Fi 7 and useful tool-free installation features. It is especially worth checking when its current price undercuts the MSI.
Check Current Price on Amazon →ASUS ROG Maximus Z890 Apex
This is not a normal “premium” recommendation. Its two-DIMM layout and enthusiast controls make sense specifically for serious memory and CPU tuning. For an ordinary stock-clock gaming build, it is unnecessary.
GIGABYTE Z890 AORUS Tachyon Duo X ICE
A specialized 2026 option for extreme memory work. GIGABYTE lists support for very high DDR5 speeds and quad-rank unbuffered/CUDIMM configurations. That makes it interesting for memory enthusiasts and unusual high-capacity builds, not as a default gaming motherboard.
Which Intel CPUs make sense with Z890?
Core Ultra 7 270K Plus
Z890 makes sense if you want CPU tuning or a high-expansion platform. For a stock-clock gaming build, also compare B860 before deciding.
Core Ultra 5 250K / KF Plus
The motherboard budget deserves particular attention here. Spending so much on Z890 that the platform loses the CPU’s value advantage can be counterproductive.
Core Ultra 9 285K
High-end Z890 becomes easier to justify for sustained productivity and tuning workloads, but board choice should still be driven by expansion, I/O and overclocking requirements rather than CPU price alone.
Core Ultra 7 265K
A well-equipped mainstream Z890 is usually sufficient. Extreme OC boards make sense only when memory or processor tuning is part of the project.

Z890 motherboard FAQ
Does Z890 support Core Ultra 200S Plus processors?
Yes. Intel states that Core Ultra 200S Plus desktop processors remain compatible with existing Intel 800-series chipset motherboards. Check the motherboard manufacturer’s CPU-support list and install the required BIOS.
Do I need Z890 for a Core Ultra 7 270K Plus?
No. The processor can work with other compatible 800-series chipsets. Z890 is most useful when you need CPU/BCLK overclocking or its additional platform I/O and PCIe flexibility.
Does B860 support memory overclocking?
Yes. Intel lists memory overclocking support for both B860 and Z890. Z890 additionally enables IA/CPU and BCLK overclocking.
Is Z890 better than B860 for gaming?
Not automatically. If both boards correctly support the CPU, GPU and memory, Z890’s main advantages are tuning, expansion and connectivity. Those features do not inherently produce higher game frame rates.
Is there an Intel Z890E chipset?
No. Intel’s consumer 800-series desktop lineup includes H810, B860 and Z890. Do not confuse motherboard model names or AMD’s X870E naming with an Intel “Z890E” chipset.
Does every Z890 motherboard have Thunderbolt 4?
No. Z890 provides a larger platform connectivity budget and supports integrated Thunderbolt capability, but motherboard manufacturers decide which ports and controllers are actually exposed on each model.
Does every Z890 motherboard have Wi-Fi 7?
No. Wireless implementation is board-specific. Many modern Z890 boards include Wi-Fi 7, but some use Wi-Fi 6E or omit integrated wireless networking entirely.
How many M.2 slots do I need?
Two or three is enough for many gaming systems. Four or more becomes more useful for large game libraries, creator workloads and workstation storage. Always check lane sharing as well as the number of slots.
Should I buy a Z890 motherboard with 5Gb Ethernet?
Only if your network can use it. A 5Gb motherboard connection is valuable with a suitably fast NAS, switch and cabling, but it provides little immediate benefit on a 1Gb network.
Are two-DIMM Z890 motherboards better?
Not for everyone. Two-DIMM layouts can be advantageous for extreme memory tuning because the memory traces can be optimized more aggressively, but they reduce conventional capacity and upgrade flexibility. They make the most sense on specialist overclocking boards.
