AsRock Z790 PG-ITX/TB4 is the topic of today’s review. Phantom Gaming motherboards are not among the most powerful motherboards (all flagship motherboards belong to Taichi and AQUA), but the Phantom Gaming motherboard is still a powerful motherboard for a modern PC with all of its peripherals and power options.
This Phantom Gaming series motherboard measures 170x170mm in Mini-ITX form factor and has 4 mounting holes for chassis installation.
The reverse side is not empty (and this is logical, because the compactness of the PCB forces engineers to place part of the important element base on the back side), there are a number of controllers, some IC and two slots for an M.2 drive. The textolite is well processed: at all soldering points, not only the sharp ends are cut off, but everything is well polished. On the same side, a aluminum plate is installed. Also, the plate helps to remove heat from the back of the PCB through the thermal interface and provides rigidity to the motherboard.
Intel’s 13th generation CPUs will feature higher core clock speeds, feature more E-cores, support an additional USB 3.2 Gen2x2 connection, and support faster DDR5 memory.
Raptor Lake will not support Intel’s AVX-512 instructions, a feature that was removed from Intel’s desktop CPU lineup with Alder Lake after it was added with their 11th Generation Rocket Lake processors.
Motherboard Layout
The Z790 system chipset received 28 PCI-e lanes (20 downstream PCIe Gen 4 lanes and up to 8 downstream PCIe Gen 3 lanes), a total of 38 high-speed ports (High Speed In Out, HSIO), up to 4x integrated USB 3.2 Gen2x2 (up to 20 Gb / s) ports (although each of them requires support from two USB 3.2 Gen2, no matter from the Z790 itself or third-party hubs). The 13th generation of processors gives another 20 PCIe lanes, while 16 lanes are PCIe 5.0, 4 lanes are PCIe 4.0.’
The AsRock Phantom Gaming Z790 PG-ITX/TB4 supports 12th and 13th generation Intel Core processors.

On the rear IO itself, there are a total of eight USB ports, 2 of which are USB 3.2 Gen 2×2 (Both Thunderbolt 4 Type-C ports). The other six Type-A are USB 3.2 Gen 2 Type-A ports. Also located on the rear IO are the Wi-Fi antenna headers, the Intel Killer 2.5Gbe LAN port, as well as a Realtek ALC4082 2-plug audio stack with SPDIF. When you’re using an Intel processor come with IGPU and need video outputs, HDMI and DisplayPort 1.4 here have that covered.
The AsRock board has two DIMM slots for installing memory modules. The board supports unbuffered DDR5 (non-ECC) memory, and the maximum memory capacity is 64 GB. Of course, XMP profiles are supported. DIMM slots included metal edging to protect them from both physical damage and interference.
The PCIe x16 slot has stainless steel reinforcement that increases durability (which can be important if you change graphics cards quite often, but more importantly, such a slot can more easily withstand bending loads in case of installing a very heavy top-level graphics card. In addition, such protection protects the slot from electromagnetic interference.
The first M.2_1 receives data from the CPU (PCIe 4.0) and is mounted alongside the PCH heatsink.
Intel Z790 Chipset is directly below the heat sink
One fan cools down the heat sink that connects directly to the heat pipe on the VRM components.
To power the board, it has 2 connectors: in addition to the 24-pin ATX (it is on the right side of the board (on the left in the photo), there is also an 8-pin EPS12V.
The processor power supply scheme is made according to the 10 + 1 + 1 scheme (12 phases in total, 10 for VCore, 1 for iGPU and 1 for VCCIO).
Each phase channel has a super ferrite choke and RAA 22010540 MOSFET from Renesas at 105A for VCore, ISL99360 at 60A for the integrated graphics core and SiC450 from Vishay for VCCIO at 40A. Powering the VCore and iGPU is Renesas’ RAA229131 PWM controller with a maximum of 20 phases, so we see that the power circuit is fully direct without doublers or parallel flows.
