Verdict

The ASRock Z790 PG-ITX/TB4 is a high-end Mini-ITX motherboard featuring a robust 10+1+1 power phase design with 105A Smart Power Stages and a 10-layer PCB optimized for Intel 12th, 13th, and 14th Gen processors. Key specifications include support for dual-channel DDR5 memory up to 7000+(OC), a PCIe 5.0 x16 slot, and an impressive storage array of three M.2 slots (all PCIe Gen4x4) and three SATA3 ports. Its standout characteristics are the dual Thunderbolt 4 ports (40Gbps), Killer 2.5G LAN, and Wi-Fi 6E connectivity with DoubleShot Pro support, alongside a premium Realtek ALC4082 audio codec. Main pros include exceptional I/O for its size and stable VRM performance; however, users should note cons such as high VRM temperatures under extreme loads despite active cooling and a limited number of rear USB Type-A ports (six).
