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.

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.

    Big thanks for the explanation, BGentry.

    Asus is a large OEM manufacturer and just doesn't make anything interesting anymore. That isn't a bad thing, except for innovation.

    ASUS defaults to Intel recommended settings for turbo and voltage, and gives users the option to increase these in line with ASUS recommendations to get the best performance. The other manufacturers simply operate with their recommended settings out of the box, hence longer and higher turbos.

    Note that Intel actually encourages vendors to set their own turbo length and turbo power - what Intel provides is recommendations, but as long as the MB vendors aren't actually overclocking the frequency, they don't particularly care.

    We typically test with out-of-the-box settings, to give a sense of what performance that users without any knowledge of what a turbo power limit is should expect. Given ASUS' implementation, it means they fall down on this metric, which makes it appear if the board is worse. What we should have done in this case is posted both sets of numbers and specified the difference, which is our fault. How ASUS does their options is going to be the focus of our Hero review.

    Thanks for the comment Ian. I always do my own setting so I never noticed this, I'm glad you brought it to attention.
  • Peskarik - Thursday, May 28, 2020 - link

    Thank you, Ian! I look forward to it. For my next system I would like ASUS board + card, just to be sure all drivers etc are in line, that is why I am looking at the performance of ASUS boards in particular.

    I used to only buy Asus, but i keep hearing crappy things about their ROG lines. To get similar features cost almost double in the current ROG lines vs Giga or MSI.

    Seems like the lower Asus lines are ok. What are you guys experiencing?
  • khanikun - Tuesday, June 2, 2020 - link

    I got away from Asus. I stuck with them for like 10 years, but in the later years, my Asus boards kept breaking. I swapped to their WS line, which worked for a while, but then it seems they turned crappy too. They'd die in 1 to 1 1/2 years. Maybe I'm just super unlucky with Asus. I just gave up on them and moved to Gigabyte.

    Kind of makes me wish Abit was still around and was like their old heyday in the early 2000s. I had a good like 6-7 year run on my old IC7-Max 3 board, until the caps started leaking.

    Gotta love how the word "Taichi" totally matches well with the whole brass cogs and gears theme plastered all over the plastic coverings they use to hide the PCB for - well who knows what reason. PCBs in computers must be considered ugly or something. Next stop, PCB-free, RGB-equipped windowed desktop computers!!!

    When Jobs started NeXT - even the motherboard went through the aesthetic department.

    I support removing polychlorinated biphenyls from desktop computers - almost as insidious as RGB Disco lights. Windows are for cars, boats, airplanes, houses and not for PC cases.

    I rather like the look of printed circuit boards in PCs - and the idea that you have several billion precision manufactured features in every CPU.

    ASRock have come a long way. I used be an ABit guy before latching on to ASUS up until Haswell. I had the opportunity to get a great deal on ASRock's Supercarrier Z270 paired with a 7700K. Superb board, tons of features, stable and overclocks quite well (5.1 GHz all cores with no effort).

    I must say, I miss the glory days of overclocking, i.e. tweaking the hell out of a DFI NF4 + TCCD + BH5 and employing crazy sh!% like the OCZ DDR booster.
