ASUS ROG Zenith II Extreme DDR4 AMD Motherboard

The ASUS ROG Zenith II Extreme is a high-end desktop (HEDT) motherboard engineered specifically for AMD Socket sTRX4 and 3rd Generation AMD Ryzen Threadripper Series processors. Built on the AMD TRX40 chipset, it delivers the platform bandwidth and power delivery that multi-core Threadripper workloads demand, whether you’re running CPU-intensive rendering, large-dataset compute jobs, or multi-GPU creative pipelines. At the heart of the power subsystem are 16 Infineon TDA21472 power stages paired with ProCool II power connectors, microfine alloy chokes, and 10K-rated capacitors. This robust VRM design handles the rapid current swings inherent to modern high-core-count processors, keeping the system stable even under sustained overclocked loads. An active-cooling VRM heatsink and a PCIe-zone M.2 aluminium heatsink work alongside an included Fan Extension Card II and dedicated water-cooling zone headers to keep thermals in check across the entire board. Storage flexibility is a key strength. The Zenith II Extreme supports up to five M.2 drives simultaneously: a DIMM.2 module hosts two M.2 slots (supporting SATA and PCIe 4.0 x4 drives in sizes up to 22110), two additional board M.2 slots run PCIe 4.0 x4 (up to 2280), and a fourth M.2 slot runs PCIe 4.0 x4/x2. Eight SATA 6 Gb/s ports round out storage, and RAID 0, 1, and 10 arrays are supported. Networking is equally capable. A dual-port LAN configuration combines an Aquantia AQC-107 10 Gbps controller with an Intel I211-AT Gigabit controller, while an onboard Wi-Fi 6 (802.11ax) module with Bluetooth 5.0 covers wireless connectivity. ROG GameFirst V traffic-prioritisation software is included. Four PCIe 4.0 x16 expansion slots support up to 3-Way NVIDIA SLI or 3-Way AMD CrossFireX multi-GPU configurations, using CPU-direct lane allocations in x16, x16/x16, x16/x8/x16, or x16/x8/x16/x8 configurations. USB connectivity is comprehensive: the rear I/O panel provides one USB 3.2 Gen 2×2 Type-C port (20 Gbps), five USB 3.2 Gen 2 ports (3× Type-A, 1× Type-C via ASMedia controller, plus one additional Gen 2×2 Type-C), and four USB 3.2 Gen 1 ports. Internal headers add further USB 3.2 Gen 2 and Gen 1 capacity. Audio is handled by a ROG SupremeFX S1220 codec delivering 8-channel HD audio with 120 dB SNR line output and 108 dB SNR recording input, supplemented by an ESS SABRE9018Q2C DAC, DTS:X Ultra, and an LED-illuminated audio trace path. An integrated colour OLED display and ASUS Aura Sync RGB system — including two standard RGB headers and two Addressable Gen 2 headers — provide system monitoring and aesthetic customisation.
