I built my main rig around the ASUS TUF Gaming Z890-PLUS WiFi three months ago, pairing it with the Intel Core Ultra 5 245K and an RTX 4070 Super. The board has handled everything from 8-hour Cinebench stress runs to marathon Baldur’s Gate 3 sessions without a hiccup. The 16+1+2+1 power stage design kept VRM temps under 65C even during extended all-core loads.
The Thunderbolt 4 Type-C port on the rear I/O is genuinely useful. I hooked up a Thunderbolt dock for my editing workflow and got 40Gbps throughput to my NVMe enclosure. WiFi 7 hit 2.8Gbps in my home lab, faster than my wired 2.5Gb connection to the router. The 2.5Gb Ethernet port handled game streaming without dropping a frame.
ASUS packed the board with four M.2 slots, and I filled three of them with PCIe 4.0 drives for games, scratch disks, and backups. The M.2 heatsinks actually work — I saw a 12C drop on my Gen4 drive under sustained writes. The PCIe 5.0 x16 slot held my RTX 4070 Super with zero flex, and Steel Armor reinforcement on the slot gave me confidence.
BIOS setup through ASUS DriverHub was painless. The AI Cooling II feature auto-tuned my fan curve based on component temps, and AI Networking II prioritized game traffic over background downloads. One minor gripe: Armoury Crate got flagged as a potentially unwanted program by my antivirus, which is annoying but not a deal-breaker.
VRM Performance Under Load
I ran Cinebench R23 multi-core for 45 minutes straight, and the VRM stayed under 68C with the default fan curve. The 80A DrMOS stages handled the 245K’s boost behavior without throttling, even with P-core clocks at 5.2 GHz. For sustained workloads, this board is rock solid.

Buying Guide for Intel Core Ultra 5 245K Motherboards
Choosing the right motherboard for the Intel Core Ultra 5 245K comes down to understanding chipset features, power delivery, and expansion needs. The 245K is a K-series chip, which means you want a Z890 board to unlock overclocking. B860 boards work but lock CPU multipliers, limiting performance tuning. Let me walk you through the key decision factors.
LGA 1851 Socket and Z890 Chipset Explained
The Intel Core Ultra 5 245K uses the LGA 1851 socket, which replaced LGA 1700 with the Core Ultra Series 2 launch. The Z890 chipset is the flagship 800-series option, offering CPU overclocking, DDR5 memory overclocking, and full PCIe 5.0 support. B860 is the mid-range option without CPU overclocking but with most modern features.
For the 245K specifically, Z890 is the recommended choice. The K-series chip is designed for overclocking, and pairing it with a B860 board wastes that capability. If you do not plan to overclock, a good B860 board will work, but you will not see the full performance potential of the 245K.
VRM and Power Delivery Considerations
The 245K has a 125W base TDP with boost power pushing past 150W. You need a motherboard with at least 12 power stages rated for 60A or higher. Boards with 16+ stages and 80A+ Smart Power Stages handle the 245K comfortably, even under sustained loads.
VRM thermals matter as much as the stage count. Look for boards with large heatsinks, heatpipes, and high-quality thermal pads. The boards in this roundup all stayed under 75C during stress tests, which is well within safe operating limits.
Memory Support: DDR5 Speeds
All Z890 boards support DDR5, but speed support varies. Entry-level boards cap at DDR5-6400 or 7200, while premium boards support 8000+ MT/s with overclocking. For the 245K, DDR5-6000 is the sweet spot for price-to-performance, but faster kits deliver measurable gains in memory-sensitive workloads.
XMP and EXPO profiles let you run your RAM at rated speeds without manual tuning. All boards in this roundup support XMP, though ASUS AEMP III and MSI Memory Boost offer additional automatic tuning.
Storage: M.2 and PCIe 5.0
Most Z890 boards include at least three M.2 slots, with premium boards offering five or more. PCIe 5.0 M.2 slots deliver 14,000 MB/s read speeds with compatible Gen5 NVMe drives, though Gen4 drives at 7,000 MB/s are still excellent for most workloads.
If you plan to run multiple NVMe drives, check the M.2 slot configuration carefully. Some boards disable certain SATA ports when M.2 slots are populated, which can affect storage expansion.
Connectivity: Thunderbolt 4, USB, WiFi 7
Thunderbolt 4 is becoming standard on Z890 boards, delivering 40Gbps throughput for docks, storage, and displays. USB-C with Power Delivery is useful for charging devices and connecting front-panel ports. WiFi 7 is the latest wireless standard, offering speeds above 2 Gbps in close-range conditions.
For wired networking, 2.5GbE is standard, with 5GbE and 10GbE appearing on premium boards. If you have a fast NAS or internet connection above 2.5 Gbps, 5GbE is worth the upgrade. Otherwise, 2.5GbE is plenty for gaming and most productivity workloads.
