In our first Intel Z490 motherboard review, the ASRock Z490 Taichi takes center stage. With its recognizable Taichi clockwork inspired design, a 12+2 power delivery, three PCIe 3.0 x4 M.2 slots, and a Realtek 2.5 gigabit Ethernet port on the rear panel, it looks to leave its stamp on the Z490 market. The Taichi remains one of ASRock's perennial premium mid-range models.

Taichi My Cogs

Back in 2017, ASRock first introduced its uniquely styled and impressive cost-to-performance Taichi series on Intel's X99 HEDT chipset. Fast forward to the present day and the Taichi series has come on leaps and bounds in both design, specifications, and features.

Enter the latest version, the ASRock Z490 Taichi, which is an ATX sized model catering to the upper echelon of the mid-range segment with some very notable inclusions. Intel is also introducing its LGA1200 socket, which supports Intel's 10th generation processors. There isn't much difference between the new Z490 and the previous Z390 chipsets in terms of specifications, which leaves the onus on motherboard vendors to make its mark through designs, controllers, and refinements.

Over the last few years, ASRock has been updating the Taichi aesthetic with various design traits, including clockwork style heatsinks and patternings, with swathes of RGB integrated into the heatsinks. The ASRock Z490 Taichi is one of its most premium revisions yet, with a black and copper theme complemented by its fashionable clockwork styled chipset heatsink. The rear panel cover is a made from plastic, but visually it looks metal due to its brushed copper printing, with two RGB enabled zones specific to this area; the Taichi logo and around the model number.

Moving down the board is three full-length PCIe 3.0 slots which run at x16, x8/x8, and x8/x8/+4 and are surrounded by plastic PCIe armor and aluminium M.2 heatsinks. The chipset heatsink also includes some RGB LEDs which is designed to make the cogwheel inside 'pop' in a chassis, with some RGB LEDs also located on the underside of the board at the right-hand side. There are three PCIe 3.0 x4 M.2 slots with the bottom two including support for SATA drives, while the board also uses eight SATA ports, six from the chipset and two from an ASMedia SATA controller.

Overall vendors have upped its support for faster memory through its QVL listings on its Z490 models. This could be from better componentry and memory routing refinements as much as it is from a stronger memory controller on Intel's Comet Lake desktop processors. The ASRock Z490 Taichi has official support for up to DDR4-4666, with a total capacity of up to 128 GB is supported across its four slots. 

Realtek RTL8125BG 2.5 G Ethernet Controller on the rear of the ASRock Z490 Taichi

One of the most improved elements from Z490 models to Z390 models in terms of product evolution from vendors is on the networking front. The ASRock Z490 Taichi offers both a Realtek RTL8125BG 2.5 G and Intel I219-V Gigabit Ethernet controller pairing. Also present is an Intel AX201 Wi-Fi 6 module, with plenty of rear panel USB 3.2 G2 connectivity on the rear panel. The ASRock Z490 Taichi has a partially covered backplate, which includes cooling for the rear of the power delivery and the Realtek RTL8125BG which is located on the rear of the PCB.

Also improved for Z490 is the power delivery. The Z490 Taichi features a 12+2 power delivery driven by an Intersil ISL69269 PWM controller, with SiC654 50 A power stages which runs in 6+1 with the use of doublers. Interestingly ASRock has including an active power delivery cooling solution with dual fans which spin up only when it is running hot.

Only powers on when thermals are super high

Accompanying the power delivery is two 8-pin 12 V ATX CPU power inputs, while along the bottom of the board is a two-digit LED debugger, a power button, and a reset button.

In regards to performance, the ASRock Z490 Taichi is competitive with other Z490 models on test. It trades blows and nets some wins and losses, but all marginally, with the exception of our system tests. So far the ASRock Z490 Taichi is the most power-efficient Z490 model we've tested so far, with good performance in DPC latency. The only caveat comes in our POST time test.

Overclocking with the ASRock Z490 Taichi with our testbed Intel Core i7-10700K proved promising. We scored  consistent gains to performance when testing with our POV-Ray benchmark. The levels of VDroop when manually overclocking can be attributed to aggressive levels of loadline calibration, which when manually setting a CPU VCore, would automatically change LLC to level 1. Testing the four overclocking presets proved a little lacklustre, with not much difference in performance to default settings, which shows the Taichi to have a pretty aggressive boost profile. This was especially noticeable as default settings managed to hit temperatures hit 86°C on our premium 280mm AIO. Manually overclocking proved the best method, which is normal, with more control over all-core core frequency speeds and CPU VCore voltages.


Coming with an MSRP of $370, the ASRock Z490 Taichi has some fierce competition in the $350-400 price bracket. This includes the ASUS ROG Maximus XII Hero Wi-Fi ($399), the GIGABYTE Z490 Aorus Master ($389), and the MSI MEG Z490 Ace ($400). All of these models with the exception of the Maximus XII Hero Wi-Fi sit directly below the brand's flagship models at present and feature Wi-Fi 6 wireless interfaces and at least a 2.5 G Ethernet controller. One thing the Z490 Taichi has over the competition is a unique design and from a looks perspective, uniqueness is a good selling point when trying to select between models with similar specifications and pricing, something the Taichi has done well with over the last few years.

    Honestly this is the most inane post I've ever read. Times haven't changed for the better, Raven Ridge support took over a year after the SoC was released. I own two Raven Ridge devices. I would know.

    Even when AMD support hits mainline, it's in such a late kernel version that you better hope this "sane" distro you're referring to is willing to backport support in an update.

    Dunno what you mean about the Nvidia driver being painless to use. Its Wayland support is still comparatively unstable in Gnome and pushes KDE Wayland support from mediocre to bad. It also requires extra build tools.

    I can't edit posts but I explained a key usage of nested Hyper-V. "Anyone who wants to use the Windows 10X emulator needs it unfortunately." There's also plenty of other features that use Hyper-V these days from WSL2 to Windows Sandbox, so the antiquated views on Hyper-V are also quite dated. Times have changed for the better, and Hyper-V is very much part of the present.

    Congrats on your condescension though! It almost masks how wrong you are.

    Why in the world do you insist on benchmarking Non-UEFI POST Time when no one will use that?
  • TheinsanegamerN - Thursday, May 28, 2020 - link

    Because not everyone is you and there are those of us that DO use it. Wow, what an amazing thought.
  • Dorkaman - Thursday, May 28, 2020 - link

    I would love to see UEFI post time AND Windpows clean knstall boot time. My old Asus Rampage V Extreme was very slow (40s post+boot no mem test hybrid) and the new Asus ROG Maximus XII Extreme is also very slow.

    My Gigabyte Z390 Aorus Master posts+boots in 10+5 seconds.
  • Dug - Wednesday, June 3, 2020 - link

    Why would you be buying new equipment for outdated OS's that aren't supported?
    If that's the case, the boot time is irrelevant, and my post still stands. Why even bother benchmarking it?

    A good read, always a pleasure to peruse Anandtech. The aesthetics are not for everyone but personally I think it's a nice looking board. Out of my price range but Z490 is not for me anyway. As to Asus boards, I have an older Z97 Maximus Hero VII and a Z390 Prime. Both great boards that have given me no significant issues.

    Do the new CPUs have an additional 4x lanes from the CPU?

    I keep seeing boards that advertise 8,8,4 slots, with all of them coming from the CPU. And this motherboard for example that has the 4x gen 4 M.2, when the chipset does not have Gen 4
  • MDD1963 - Wednesday, May 27, 2020 - link

    The specs I read said the top GPU slot would be capable of PCI-e 4.0 x16, ...and one of the M.2 slots...( perhaps I missed where it said all 4 might be capable fo PCI-e 4.0 x4 operation?_)

    Even with the aforementioned limits, more than enough for 99% of most folks....

    Waiting to see how many people show up to the comments to wail about the tiny fans. After all, it wasn't anti-AMD sentiment that caused so many folks to show to all of the articles related to X570 boards (and a few that weren't) and do that, it was totally neutral concerns about longevity and noise.

    (Full disclosure - I am fully on-board with not wanting tiny fans on a motherboard... just feeling a little amused by the asymmetry of this. The only comment here so far on this topic has been a sensible one, not hysterical ranting.)
  • TheinsanegamerN - Thursday, May 28, 2020 - link

    So you smugly, disingenuously re-categorize the arguments of others and think you're...clever? Funny? Intelligent?

    Now, here's points for asrock that might blow your mind, these are STANDARD FANS. You can go buy brand new noctuas to replace these and silence them while maintaining cooling performance. Guess what you couldnt do with x570 chipset fans? These fans also dont spin 24/7, only when needed, and the VRMs here get a LOT hotter then the x570 chipset did.

    If X570 got into the 90C range without the active cooling (it doesnt) and they used standard 40mm fans (they dont) then the complaints would be baseless. But we saw how necessary those x570 fans really were. And oh hey, there are plenty of Z490 mtoherboards that dont use VRM fans! Just like that whole 1 X570 motherboard that cost like $700!
