The ASUS TUF Gaming Z890-PLUS WiFi is an ATX motherboard built for Intel LGA 1851 and Core Ultra Series 2 processors. It is designed for gamers, creators and power users who want a durable, AI ready foundation with extensive future proof connectivity.
In real world use it delivers stable, responsive performance thanks to its 16+1+2+1 80A DrMOS power stages and PCIe 5.0 support for graphics and storage. Users highlight easy first time setup with ASUS DriverHub and reliable handling of heavy multitasking, while Wi-Fi 7, Intel 2.5Gb Ethernet and Thunderbolt 4 keep transfers and networking fast.
Build quality is a clear strength, with an 8-layer PCB, alloy chokes, durable capacitors and large VRM, M.2 and PCH heatsinks. The reinforced PCIe 5.0 SafeSlot with Q-Release, four M.2 slots and hybrid fan headers managed by Fan Xpert 4 and AI Cooling II make assembly and cooling straightforward and effective.
There are some drawbacks to note. A few users have reported reliability issues like nonfunctional memory channels, which suggests quality control can vary. Its full ATX footprint and premium connectivity also make it larger and more feature rich than many casual builds need.
Overall the Z890-PLUS WiFi is a well balanced choice for a high performance Intel build that needs longevity and versatility. If you want DDR5, PCIe 5.0, Wi-Fi 7 and Thunderbolt 4 in a tough, intelligently cooled package, it is a compelling and capable option.
How They Compare
These two ATX boards share the LGA 1851 socket and DDR5 support, but the Z890 platform adds overclocking and extra lanes while B860 keeps the essentials. We evaluated each board per the spec sheet and according to owners, with attention to what actually changes your daily experience.
Power Delivery and Overclocking Support
The GIGABYTE B860 DS3H WIFI6E Intel Core uses an 8+1+2+2 phase design with 50A PPAK VRM components, which is designed for stock operation of Intel Core Ultra Processors (Series 2) with solid efficiency. The ASUS TUF Gaming Z890-PLUS WiFi Z890 LGA 1851 ATX steps up to 16+1+2+1 stages with 80A DrMOS, ProCool power connectors, an 8-layer PCB, alloy chokes and durable capacitors for more stable delivery under sustained load.
That difference matters because Z890 is the chipset that supports CPU and memory overclocking, while B860 does not. If you plan to run a locked Core Ultra at stock settings, the GIGABYTE power design is reviewed as capable and efficient. If you want to tune multipliers, push DDR5, or sustain higher power limits for longer, the ASUS board is the more premium choice with headroom to spare. As always, check cooler height and radiator clearance against your case and follow the manufacturer mounting instructions, and handle components with anti-static precautions.
Storage, PCIe and Expansion
Both boards offer PCIe 5.0 for graphics, but their storage layouts differ. The GIGABYTE B860 DS3H WIFI6E Intel Core lists PCIe 5.0 support with 2x M.2 slots in its key features and 3X M.2 in its overview description, plus USB-C, which covers a primary PCIe 5.0 drive and a secondary drive for most gaming builds. The ASUS TUF Gaming Z890-PLUS WiFi Z890 LGA 1851 ATX provides PCIe 5.0 x16 SafeSlot with PCIe Slot Q-Release and four M.2 slots, including one slot that supports PCIe 5.0, giving you more simultaneous NVMe options.
For a single GPU plus one or two NVMe drives, either board is assessed as practical. If you want a PCIe 5.0 boot drive plus multiple PCIe 4.0 drives for games and creation, or you plan to add capture or networking cards later, the ASUS layout is more flexible. The GIGABYTE board keeps expansion simpler and more affordable, while the ASUS board gives you room to grow without swapping drives.

Networking and Rear I/O
Networking is a clear split. The GIGABYTE B860 DS3H WIFI6E Intel Core includes WIFI6E and 2.5GbE LAN, which remains fast and widely compatible with current routers. The ASUS TUF Gaming Z890-PLUS WiFi Z890 LGA 1851 ATX moves to Wi-Fi 7 with Intel 2.5Gb Ethernet and adds AI Networking II, plus Thunderbolt 4 Type-C, DisplayPort and HDMI for versatile display and peripheral support.
In practice, WIFI6E is more than enough if your router is Wi-Fi 6 or 6E and you use wired 2.5GbE for your desktop. Wi-Fi 7 and Thunderbolt 4 on the ASUS board are more future oriented, useful if you own a Wi-Fi 7 mesh system, a Thunderbolt dock, or high speed external storage. Owners commonly report that both boards connect reliably, but the ASUS board offers broader high bandwidth I/O for creators who move large files. Consider your router and dock ecosystem before paying for the newer standard.
Thermal Design and Builder Friendly Features
Thermals and ease of building also separate them. The GIGABYTE B860 DS3H WIFI6E Intel Core provides a MOSFET heatsink and M.2 Thermal Guard, plus DIY features like M.2 EZ-Latch, PCIe EZ-Latch and WIFI EZ-Plug that simplify installation and antenna setup. The ASUS TUF Gaming Z890-PLUS WiFi Z890 LGA 1851 ATX uses large VRM heatsinks, dedicated M.2 and PCH heatsinks, hybrid fan headers and Fan Xpert 4 with AI Cooling II to manage airflow and noise more granularly.
If you prefer a quick, tool-light build with fewer cables to manage, the GIGABYTE EZ features are appreciated by first time builders. If you run multiple fans, a large air cooler, or an AIO and want automated fan curves, the ASUS thermal system and AI Cooling II give you finer control. Either way, verify CPU cooler clearance and M.2 heatsink height against your case, follow the board manual for fan header amperage, and note that BIOS updates are done at your own risk and may affect warranty.

Which One Should You Get
Choose the GIGABYTE B860 DS3H WIFI6E Intel Core if you want a straightforward Core Ultra Series 2 foundation for 1440p gaming and general use without overclocking. It is a good fit for a DDR5 build with 4 DIMMs, a single modern GPU on PCIe 5.0, and one or two M.2 drives, especially when you want WIFI6E and 2.5GbE without paying for extra lanes you will not use. Pair it with a mid tower that has good front airflow, a sensibly sized air cooler or 240mm AIO that fits your case, and you have a balanced system that leaves budget for your graphics card. You can explore cost conscious part combinations in our Budget Build Guides to stretch that saving further.
Choose the ASUS TUF Gaming Z890-PLUS WiFi Z890 LGA 1851 ATX if you want tuning, more storage, and richer I/O for a higher end Core Ultra build. The 16+1+2+1 80A DrMOS design, 8-layer PCB, four M.2 slots with one PCIe 5.0 slot, PCIe 5.0 x16 SafeSlot with Q-Release, Wi-Fi 7, and Thunderbolt 4 Type-C make it the better platform for overclocking, multiple NVMe drives, and Thunderbolt peripherals. It suits builders who plan to keep the board through several GPU generations, run demanding AI or creation workloads, or fine tune memory and power limits. If that is your path, the ASUS board justifies its position as the higher end pick.
Who Should Skip Both
Neither board is ideal for compact small form factor builds that require Mini-ITX or Micro-ATX sizing, since both are ATX and need a mid tower or larger case with proper standoff support. This pair is also not a good fit if you are on an older Intel socket or AMD platform and do not plan to move to LGA 1851 and DDR5, or if you need workstation class features like 10GbE onboard or extensive PCIe bifurcation. If you want the smallest possible system, a strict budget DDR4 reuse plan, or a board with different socket support, you should look at other chipsets and form factors instead.
Frequently Asked Questions
Can both boards run Intel Core Ultra Series 2 CPUs on LGA 1851 with DDR5?
Yes. Both the GIGABYTE B860 DS3H WIFI6E Intel Core and the ASUS TUF Gaming Z890-PLUS WiFi Z890 LGA 1851 ATX list support for Intel Core Ultra Processors (Series 2) on LGA 1851 and DDR5 memory. The GIGABYTE board specifies 4 DIMMs, while the ASUS board also supports DDR5 with its TUF memory tuning features.
Do I need Z890 if I do not plan to overclock?
Not necessarily. B860 covers stock operation, PCIe 5.0 graphics, and modern connectivity like WIFI6E and 2.5GbE for most gaming builds. Z890 is the right choice if you specifically want CPU or memory overclocking, more M.2 slots, or Thunderbolt 4 and Wi-Fi 7 for future peripherals.
How do M.2 and PCIe 5.0 differ between these two boards?
The GIGABYTE B860 DS3H WIFI6E Intel Core offers PCIe 5.0 with 2x M.2 slots per its key features, described as 3X M.2 overall, plus M.2 Thermal Guard and EZ-Latch. The ASUS TUF Gaming Z890-PLUS WiFi Z890 LGA 1851 ATX provides four M.2 slots including one PCIe 5.0 slot, PCIe 5.0 x16 SafeSlot with Q-Release, and larger heatsinks for sustained drive performance.
