ASRock Z590 Taichi Review: An Intel Motherboard with Moving Parts (and Thunderbolt 4)by Gavin Bonshor on April 1, 2021 11:00 AM EST
The overall design of the Taichi series has followed a progressive trajectory over the last couple of years. Sitting now as one of ASRock's more premium models. the entire aesthetic has revolved around the use of cogwheels what the company itself dubs as the 'Philosophy of Infinite Potential'. For Z590, the Taichi moves to an all-black design, with a plain black PCB, black heatsinks, and primarily black PCIe slot armor. The Z590 Taichi has plenty of customizable RGB LED lighting, with four zones including two in the plastic rear panel cover, one area within the chipset heatsink, and along the right-hand side of the board which creates an under glow effect.
Dominating the lower section of the board is the PCIe slot area. The ASRock Z590 Taichi includes two full-length PCIe 4.0 slots that can operate at x16 and x8/x8, a third full-length slot electronically locked down to PCIe 3.0 x4, and a single PCIe 3.0 x1 slot. All three of the board's full-length slots include ASRock's Steel Slot reinforcement, with the PCIe armor blending in nicely with M.2 heatsinks. Touching on the storage, the Z590 Taichi includes one PCIe 4.0 x4 M.2 slot, and two PCIe 3.0 x4 M.2 slots that also support SATA. For SATA devices, ASRock includes a combined total of eight, with six powered by the chipset and two driven by an ASMedia ASM1061 SATA controller. As expected, the six SATA ports from the chipset support RAID 0, 1, 5, and 10 arrays. Below are the limitations on storage devices due to bandwidth sharing between slots/connectors:
- M2_2, SATA3_0, and SATA 3_1 share bandwidth, if one is used, it disables the other two
- M2_3, SATA3_4 and SATA3_5 and PCIE_4 share bandwidth. if one is used, it disables the other three
Along the bottom of the board towards the right-hand corner, there's a small overclockers toolkit which consists of a power button, a reset button, a two-digit LED debugger, and a small clear CMOS button. Around the board's edge is a total of eight 4-pin headers which include one for a CPU fan, one doubling up as a CPU fan and water pump header, and six for chassis fans. Other useful front panel headers include a single USB 3.2 G2x2 Type-C header, two USB 3.2 G1 Type-A headers (four ports), and two USB 2.0 headers (two ports).
The moving cogwheel built into the Z590 Taichi rear panel cover.
One of the new and interesting things about the Z590 Taichi's new design is that it has implemented a mechanical cogwheel into the rear panel cover. This can spin both clockwise and anti-clockwise with a stepping motor providing power and rotation to the cog. Within the firmware, users can adjust the time interval between the rotations, including 5, 10, 30, and 60-minute intervals, or of course switch it off altogether.
In the top right-hand corner, there are four memory slots in total, which include support for up to DDR4-5000 out of the box. This also includes support for up to 128 GB, with official support for non-ECC memory modules only. As with all of Intel's Z590 models, memory kits with Intel XMP 2.0 memory profiles are support.
The ASRock Z590 Taichi is using a premium 14-phase power delivery operating in a 6+2 configuration. The CPU section includes twelve Renesas ISL99390 90 A SPS power stages with six Reneasas ISL6617A doublers. ASRock includes two ISL99390 90 A SPS power stages for the SoC section, with a Renesas ISL69269 PWM controller operating in 6+2 mode. In addition to this, each physical power stage includes 90 A alloy inductors, with a total of fourteen present. Overall, the Z590 Taichi can deliver up to 1080 A of current on the CPU side, with two 8-pin 12 V ATX CPU power inputs delivering the power. Using doublers is a conventional way of adding in more operating phases which can effectively reduce the overall temperature with the aim of increasing thermal efficiency, without sacrificing too much in the way of VDroop and overall power efficiency.
Cooling the power delivery is a large pair of heatsinks, which are interconnected via a large single heat pipe. Integrated into the CPU section is a small cooling fan, which makes the power delivery an actively cooled solution. ASRock includes a pair of brackets, one for a 3 cm fan without included in the bundle, as well as a 4 cm bracket for users wishing to add their own. This can be installed onto the end of the SoC area heatsink, with pre-installed mounting holes available to use.
At the back of the board, the Z590 Taichi includes a half-cover backplate, which adds extra thermal properties to the back of the power delivery, as well as extra rigidity across the board. It's black, includes some Taichi cogwheel design, primarily behind the chipset heatsink, although the likelihood of seeing this within a system is slim in a conventional chassis.
Looking at the onboard audio solution of the Z590 Taichi, ASRock is using a Realtek ALC1220 HD audio codec, with an assisting ESS Sabre 9218 DAC with an SNR of up to 130 dB, and supports headphones with an impedance of up to 600 ohms. Flanking the HD audio codec are three Japanese Gold Nichicon audio capacitors, with four WIMA audio capacitors located at the bottom. The audio PCB is separated from the rest of the board with a gold-colored separating line, which is designed to improve signal quality and reduce interference from the board's other electronic components.
On the rear panel is a good selection of input and output, including dual Thunderbolt 4 40 Gbps Type-C, which also provide support for compliant and compatible Thunderbolt monitors. What's interesting here though is that ASRock hasn't labeled these Type-C ports with the official TB4 logos. Other USB connectivity includes two USB 3.2 G2 Type-A, and four USB 3.2 G1 Type-A ports. For audio, there are five 3.5 mm audio jacks and S/PDIF optical output located in the center of the rear panel, which is all powered by a Realtek ALC1220 HD audio codec and ESS Sabre 9218 DAC pairing, with one HDMI 2.0 video output providing access to Intel's UHD integrated graphics. On the networking side of things, ASRock includes two RJ45 ports, one driven by a Killer E3100G 2.5 GbE and the other by an Intel I219-V Gigabit controller, with a Killer AX1675x Wi-Fi 6E CNVi. Finishing off the rear panel is a BIOS Flashback button.
The two USB 3.2 G1 Type-A ports located between the HDMI 2.0 and audio connectors, are what ASRock likes to call its 'Lightning Gaming Ports'. One port is designated for a keyboard and another for a mouse. ASRock says this is patent-pending, and what makes it unique is one that runs from a separate USB controller, an ASMedia ASM1042A. ASRock claims this to improve jitter latency, by reducing the amount of traffic across the USB controller.
What's in The Box
Included with the ASRock Z590 Taichi is a pretty comprehensive accessories bundle that features everything needed to get a system running out of the box. The package consists of an installation manual, three black SATA cables, two M.2 screw installation kits, as well as two Killer antenna AX1675x Wi-Fi 6E CNVi. One of the interesting additions is a USB 2.0 to 2 x Type-A header which allows users to add two USB 2.0 ports to the rear panel. This is something I haven't seen included with a motherboard for a long time.
Also included in the accessories bundle is ASRock's patent-pending Graphics Card Holder. Designed to ease the burden and help eliminate sag on heavy graphics cards, this is supplied with ASRock's more mid-range and premium options. It has a sliding mechanism for easy installation, and all of the screws come supplied as well as mounting holes on the board.

powerarmour - Thursday, April 1, 2021 - linkThat gimmicky cogwheel is quite frankly ridiculous, ASRock have really gone all-in for their own personal shark jumping contest.
abufrejoval - Thursday, April 1, 2021 - linkOne would think it a product for this special day!
Exotica - Thursday, April 1, 2021 - linkI don’t understand why some mobo vendors implement thunderbolt4 but fail to include DisplayPort inputs for pass thru of the gpu output via thunderbolt. Major fail in my opinion of asus 13 hero, aorus extreme, and the ASRock Taichi. Give the user control over which video signal they tunnel via thunderbolt: either the igpu or a discrete gpu. At least the gigabyte vision d and the msi ace have DisplayPort input.
dotes12 - Thursday, April 1, 2021 - linkI came to the comments for your exact comment. I assume you can tunnel your PCIe GPU through the CPU's GPU just like you can on previous Intel boards, but what is the performance penalty for that? Seems like having a dedicated DP input to incorporate it into TB4 would make sense if there is a performance hit.
Linustechtips12#6900xt - Monday, April 5, 2021 - linkThey did have it on the x570 AQUA, but thats kinda different segment of mobo, i guess its just kinda a rare feature to want to do, since you're really just swapping one port for another that has built in usb and other junk.
vanish1 - Thursday, April 1, 2021 - linkI think it looks great
jeremyshaw - Thursday, April 1, 2021 - link> The second cogwheel, on the rear IO cover, is a mechanical moving part, and the first time I've personally seen a mechanical moving part integrated into a motherboard.
To be fair, we have seen a LOT of fans on motherboards in the past and present.
Oxford Guy - Thursday, April 1, 2021 - linkYeah. When I read the headline I was surprised because I expected it to refer to a fan — the only moving part that has any business being part of a board.
Operandi - Thursday, April 1, 2021 - linkNothing fair about that comparison at all; one of them performs a function while the other is superfluous bullshit.
Oxford Guy - Thursday, April 1, 2021 - linkUm... they’re both moving parts. Fairness has nothing to do with it.
