ASRock X570 Phantom Gaming-ITX TB3

Well-known in recent times for its impressive mini-ITX motherboard, the ASRock X570 Phantom Gaming-ITX TB3 includes a very solid feature set. The ASRock X570 Phantom Gaming-ITX TB3 joins a small handful of small form factor X570 models at launch but looks to stand-out from the crowd with a major feature; a Thunderbolt 3 Type-C connector on the rear panel.

Following in line with the rest of its premium X570 product stack, ASRock has equipped the board with a hefty looking 10-phase power delivery, and official support for DDR4-4533 memory across two available slots with a total capacity of up to 64 GB. A single full-length PCIe 4.0 x16 slot is located at the bottom of the board, with a single PCIe 4.0 x4 M.2 slot, and just four SATA ports. The networking is handled by an Intel Gigabit LAN port, while the Wi-Fi 6 802.11ax wireless interface is controlled by the Killer AX1650 interface with support for BT 5 devices.

On the rear panel alongside the single Thunderbolt 3 Type-C connector which is the highlight of the board, the ASRock X570 Phantom Gaming-ITX TB3 also includes two USB 3.1 G2 Type-A and two USB 3.1 G1 Type-A ports. This is contradictive on the official specifications that were given to us at Computex which stated this model has two USB 3.1 G2 Type-A ports on the rear, as well as two USB 2.0 ports which also seem to be missing from the rear panel. On the display model at Computex, there is a clear CMOS button, a DisplayPort input and HDMI video output, with a PS/2 combo port, and five 3.5 mm color coded audio jacks with a S/PDIF optical output due to the use of a Realtek ALC1220 HD audio codec.

The ASRock X570 Phantom Gaming-ITX TB3 mini-ITX motherboard looks to stand out from other brands mini-ITX offerings with the Thunderbolt 3 which has been a mainstay of its desktop-focused small form factor models of recent times. A solid looking 10-phase power delivery similar to that of the ASRock Z390 Phantom Gaming-ITX/ac model we reviewed makes this even more appealing to users looking to push out the overclocks on the new Ryzen 3000 series processors. The X570 Phantom Gaming-ITX TB3 has an MSRP of $300, which is by no means cheap in comparison to its other mini-ITX models of late.

    IIRC the x16 PCIe from the CPU can only be split down to x8/8 so you'd need to add an extra (expensive) chip to farther split it to x8/4/4.

    Otherwise you only have 1 x4 from the CPU itself. The x16/4/4 that AMD claims is somewhat deceptive since one of the x4's is used for the chipset and thus not available for general use.

    Doesn't this disagree with you? Reply

    Does any of these motherboards support IPMI or something equivalent? Reply

    ASUS ROG Crosshair VIII Impact:

    "Also featured in addition to the dual PCIe 4.0 M.2 slots are eight SATA ports which is quite an impressive feat given the board's smaller form factor."

    No, it has 4 SATA ports.

    All the VRM core counts are wrong. Its as if some numbskull just counted caps and knows nothing about motherboards or cores. Reply

    This is the information we have received from the vendors themselves. Until we take a look at each board and do the analysis, it would be hard. Unless you know someone who has images/inspected each of the 35+ boards in person to do this? Reply

    Really thinking that a simple comparrison chart that listed all the MOBO's you tested on one axis and the features people might look for on the other axis with prices at the far end would have helped you reduce the wasted space on your conclusion page as well as present the findings in a more concise manner. Just food for thought. Reply

    The industry needs to make up its mind when it comes to USB C. Laptops are launching with only USB C and meanwhile $700 motherboards only have 1 USB C port and 8+ "outdated" USB A's Reply
