ASUS Prime Z790M-Plus D4 CSM DDR4 Intel Motherboard

The ASUS Prime Z790M-Plus D4 CSM is a Micro-ATX motherboard built on the Intel Z790 chipset, designed for use with 12th and 13th Generation Intel Core, Pentium Gold, and Celeron processors via the LGA1700 socket. Measuring 24.4 cm x 24.4 cm, it fits compact builds without compromising on features or connectivity. At the heart of its power delivery is a 10+1 DrMOS design paired with a 6-layer PCB, ProCool connectors, alloy chokes, and durable capacitors, providing stable and reliable power under sustained workloads. The Digi+ VRM module gives precise digital control over voltages and frequencies, while the EPU automatically adjusts power consumption for efficiency. Memory support spans four DDR4 DIMM slots with a maximum capacity of 128 GB. Native speeds start from DDR4-2133 with overclocked profiles reaching up to DDR4-5333 (OC). Intel XMP is supported, and ASUS OptiMem II optimises trace routing and ground layers to preserve signal integrity during overclocked operation. Storage is handled by three M.2 Key-M slots — one CPU-attached and two via the Z790 chipset supporting PCIe 4.0 x4 — alongside four SATA 6 Gb/s ports, with Intel RST enabling NVMe RAID 0/1/5 and SATA RAID 0/1/5/10 configurations. Expansion slots include one PCIe 5.0 x16 slot from the CPU, one PCIe 4.0 x16 slot (operating at x4) and two PCIe 4.0 x1 slots from the chipset. Rear connectivity provides eight USB ports including a USB 3.2 Gen 2x2 Type-C at 20 Gbps, plus DisplayPort 1.4 and HDMI 2.1 outputs both capable of 4K at 60 Hz. A front-panel USB 3.2 Gen 1 Type-C header and Thunderbolt header are also present. Networking is handled by an Intel 1 Gb Ethernet controller with ASUS LANGuard surge protection. Wi-Fi requires an optional M.2 Key-E CNVi or PCIe module sold separately. Audio is delivered via a Realtek HD codec supporting 7.1 surround sound at up to 24-bit/192 kHz, with audio shielding, premium capacitors, and dedicated PCB layers to reduce interference. Cooling headers include one CPU fan, one CPU OPT, one AIO pump header, and three chassis fan headers, all manageable through Fan Xpert 4 with AI Cooling II. AURA Sync RGB lighting is supported via one AURA RGB header and three Addressable Gen 2 headers. Protection features under ASUS 5X Protection III include SafeSlot reinforced PCIe, LANGuard, overvoltage protection, and USBGuard with 120% higher overvoltage tolerance.
