Supermicro C9Z790-CG ATX Motherboard — LGA 1700 (Intel H Socket), Intel Z790, DDR5 4x UDIMM (up to 128GB), Dual PCIe 5.0 x16

Overview: Supermicro C9Z790-CG is an ATX motherboard built on the Intel Z790 chipset for LGA 1700 (Intel H Socket) systems. It supports 12th- and 13th-generation Intel CPUs and offers modern DDR5 memory support, multiple M.2 bays, and dual PCIe 5.0 x16 expansion slots with reinforced armor. CPU Compatibility: Supports 12th (up to 8+8 cores) and 13th (up to 8+16 cores) Gen Intel Core i9/i7/i5/i3 processors, as well as Pentium and Celeron processors on the LGA 1700 platform. Compatible with CPUs up to TDP 125W. Memory: Four Unbuffered non-ECC UDIMM slots for DDR5 memory, supporting up to 128GB. Native DDR5 speeds up to 4400MT/s, with 5000+MT/s available via overclocking (OC). Expansion Slots: Two PCIe 5.0 x16 slots (operating as 16/NA or 8/8) with Armor protection (armor protection available only for discrete graphics or storage cards). In addition, there are two PCIe 3.0 x1 slots for smaller add-in cards. M.2 Storage: M.2 support includes one PCIe 4.0 x4 slot and two PCIe 3.0 x4 slots. RAID levels 0, 1, and 5 are supported for applicable storage configurations. M.2 form factors supported: 2260, 2280, and 22110. M.2 Key: M-Key. Networking: Provides single-port Ethernet using an Intel single Ethernet PHY i219V and an additional single-port LAN using a Marvell AQC113. Chipset: Intel Z790 — delivers the platform features required for the listed CPU and I/O capabilities. This board is ideal for builders seeking LGA 1700 compatibility with DDR5 performance, multiple high-speed M.2 slots, and flexible PCIe 5.0 expansion.
