ASUS Prime Z790-A Wifi CSM DDR5 Intel Motherboard

The ASUS Prime Z790-A WiFi CSM is an ATX form-factor motherboard built on the Intel Z790 chipset, designed for Intel LGA1700 socket processors spanning the 12th and 13th Gen Core, Pentium Gold, and Celeron families. It supports Intel Turbo Boost Technology 2.0 and Turbo Boost Max Technology 3.0, making it a strong foundation for both productivity and content creation workloads. Memory flexibility is a highlight of this board: four DIMM slots accommodate up to 128 GB of unbuffered DDR5 RAM in dual-channel configuration, with native speeds of 4800 MT/s and XMP overclocking support reaching DDR5-7200+ (OC). The ASUS OptiMem II routing technology helps maintain signal integrity at high memory frequencies. For storage, the board provides four M.2 Key-M slots — three supporting up to 22110-length drives and one accommodating 2280-length drives — all running PCIe 4.0 x4. Four SATA 6Gb/s ports complement these, with Intel Rapid Storage Technology enabling PCIe RAID 0/1/5/10 and SATA RAID 0/1/5/10 configurations. Three M.2 heatsinks cover all four slots to help prevent thermal throttling during sustained transfers. Expansion is handled by one PCIe 5.0 x16 slot (from the CPU), one PCIe 4.0 x16 slot running at x4 mode, one PCIe 4.0 x4 slot, and two PCIe 3.0 x1 slots — all sourced from the Z790 chipset. Connectivity is comprehensive: onboard Wi-Fi 6E (802.11a/b/g/n/ac/ax, 2x2, tri-band 2.4/5/6 GHz) pairs with Bluetooth 5.3, while wired networking is handled by an Intel 2.5 Gb Ethernet controller with ASUS LANGuard protection. The rear I/O panel provides eight USB ports — including a USB 3.2 Gen 2x2 Type-C (20 Gbps) and three USB 3.2 Gen 2 ports — plus DisplayPort 1.4 (up to 8K@60 Hz) and HDMI 2.1 (up to 4K@60 Hz) for integrated graphics output. Audio is handled by a Realtek S1220A codec delivering 7.1-channel surround sound with a 120 dB SNR stereo playback output and 113 dB SNR recording input, supported by dedicated audio PCB layers, audio shielding, and premium capacitors. Power delivery uses a 16+1 teamed power stage design with 60 A-rated MOSFET packages and ProCool 8+8-pin solid-pin CPU power connectors. The ASUS Corporate Stable Model (CSM) designation provides up to 36 months of product lifecycle support, a 6-month end-of-life notice, and bundled ASUS Control Center Express IT management software — making this board well-suited for enterprise and commercial deployments.
