ASUS Prime H670-Plus DDR4 Intel Motherboard

The ASUS Prime H670-Plus D4 is a full-size ATX motherboard (30.5 cm × 24.4 cm) built around the Intel H670 chipset and the LGA1700 socket, making it compatible with 12th Generation Intel Core, Pentium Gold, and Celeron processors. It is a practical, feature-rich foundation for productivity-focused desktop builds that demand reliable power delivery, fast storage, and comprehensive connectivity. Memory support spans four DIMM slots with a maximum capacity of 128 GB of DDR4 memory running in Dual-Channel configuration. Speeds range from DDR4-2133 at JEDEC spec up to DDR4-5066 via XMP overclock profiles. ASUS OptiMem trace-routing technology reduces signal-path distance across PCB layers and adds shielding zones to lower crosstalk, contributing to improved memory stability and compatibility. Storage options are generous: three Key-M M.2 slots support PCIe 4.0 x4 (up to 64 Gbps each), with M.2_3 also accepting SATA-mode drives. Four SATA 6 Gb/s ports provide additional capacity. Intel Rapid Storage Technology enables NVMe RAID 0/1/5 and SATA RAID 0/1/5/10. Expansion is handled by one PCIe 4.0 x16 slot (CPU-direct) for discrete graphics, one PCIe 4.0 x16 slot operating at x4 mode, one PCIe 3.0 x16 slot at x4 mode, and two PCIe 3.0 x1 slots — all from the H670 chipset. The reinforced SafeSlot Core+ primary slot protects heavy graphics cards. Connectivity highlights include Realtek 2.5 Gb Ethernet with ASUS LANGuard surge protection, a rear USB 3.2 Gen 2 Type-C port, two rear USB 3.2 Gen 2 Type-A ports, three rear USB 3.2 Gen 1 Type-A ports, and a Thunderbolt 4 onboard header compatible with the ASUS ThunderboltEX 4 add-in card (supporting up to 40 Gbps bi-directional). Integrated display outputs include DisplayPort 1.4 (4K@60 Hz) and HDMI 2.1 (4K@60 Hz) for systems using Intel integrated graphics. Audio is handled by a Realtek HD 7.1-channel CODEC supporting up to 24-bit/192 kHz playback, with audio shielding, dedicated PCB layers, and premium capacitors to reduce interference. RGB customisation is available via two AURA RGB headers and three Addressable Gen 2 headers, all manageable through ASUS Armoury Crate software. The UEFI AMI BIOS (192 Mb Flash ROM) provides both an EZ Mode for quick setup and an Advanced Mode for granular tuning. ASUS Fan Xpert 2+ controls one CPU fan header, one AIO pump header, and three chassis fan headers. The Energy Processing Unit (EPU) automatically adjusts power draw to reduce consumption during light workloads.
