Visual Inspection

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.

    What?

    I was replying to the comment comparing a mechanical visual embellishment to fan that serves a function. If you bring up one thing in relation to another that typically means drawing a comparison or in this case a likeness between them. However in the case one of them is functional and does something while the other is pointless and stupid, thus making it an unfair comparison.

    Taichi - from "we give you only the necessary and meaningful features..." to "have a turning cog just because". Reply

    This is the beginning of the end for sensible looking hardware. By 2023 motherboards will be 50% greebles by weight. Reply

    ‘Although PCIe 4.0 has been seen on AMD platforms for over a year, it's a solid statement from Intel as they look to regain its position as the king in the processor market.’

    The king of 14nm.

    I find 2.5Gbit Ethernet at these price levels more than a bit disappointing. I think the RealTek 2.5Gbit would sell at rather similar cost to their Gbit offerings as BOM, so "premium" isn't what comes to mind at this speed.

    Currently you have to either sacrifice an entire PCIe 4x (or greater) slot or a Thunderbolt port to get 10Gbit via Aquantia/Marvell, 8x for Intel 10Gbit (which might not be NBase-T but 1/10GBaseT, only), when a single PCIe 4.0 lane should suffice.

    Surely 3 Watts for a 10GBase-T PHY aren't too much to ask when the CPU gobles 400 and the GPU not much less!

    As of 30th March they've posted a new BIOS/Firmware that fixes a bunch of CPU issues. What version were you testing? Reply

    If I pay more than $400 for a motherboard, I will definitely get one with 12 or more REAL power phase, not ones that using doublers. Reply

    I don’t think doublers are necessarily bad. It’s in the implementation.

    In the bigger picture, just get Zen 3 and don’t worry about overclocking and VRMs.

    So you'll pay more for something that functions identically? Arguably doublers have the benefit of being easier to sync since they only use 6-8 controllers instead of 12-16, which allows for better voltage control. Reply

    Not all doubler implementations are as good as implementations without them. Some are particularly poor. It comes down to the implementation but, in the simplest example a doubler is not as good as having separate phases. There are a lot of variables involved, though. Separate low-quality phases are going to be worse than high-quality phases using a doubler.

    Buildzoid explained all of the details in his videos. I don't remember all of the specifics but some VRM implementations are full of fakery, like adding lots of chokes or something to fool people into thinking they're getting something more powerful.
