ASUS Prime H770-Plus D4 DDR4 Intel Motherboard

The ASUS Prime H770-Plus D4 is an ATX form-factor motherboard built on the Intel H770 chipset, designed for Intel LGA 1700 socket processors including 12th and 13th Generation Intel Core, Pentium Gold, and Celeron series. Its full ATX dimensions of 12 x 9.6 inches (30.5 x 24.4 cm) make it compatible with standard mid-tower and full-tower cases. For storage, the board provides three M.2 Key-M slots all running at PCIe 4.0 x4 for sequential speeds up to 64 Gbps, alongside four SATA 6 Gb/s ports. The primary PCIe slot runs at PCIe 5.0 x16, suitable for current discrete graphics cards, while two additional PCIe 4.0 x16 slots (operating in x4 mode) and two PCIe 3.0 x1 slots round out expansion options. Memory is handled by four DDR4 DIMM slots supporting up to 128 GB of unbuffered, non-ECC RAM in dual-channel configuration. Native speeds up to DDR4-3200 are supported, with overclocked profiles reaching DDR4-5066 via XMP. ASUS OptiMem technology optimises trace routing to preserve signal integrity and reduce crosstalk. Connectivity on the rear I/O panel includes a Realtek 2.5 Gb Ethernet port, three USB 3.2 Gen 2 ports (two Type-A and one Type-C), three USB 3.2 Gen 1 Type-A ports, two USB 2.0 Type-A ports, a DisplayPort output, an HDMI port, a vertical M.2 Key-E slot for optional Wi-Fi/Bluetooth modules, and three audio jacks backed by a Realtek 7.1 surround sound HD audio codec with 24-bit/192 kHz playback support. A Thunderbolt (USB4) internal header is also present for compatible expansion cards. Thermal management is addressed by a VRM heatsink, an M.2 heatsink with captive screws, and a PCH heatsink, complemented by one CPU fan header, one AIO pump header, and three chassis fan headers—all manageable via Fan Xpert 2+ software. Three Addressable Gen 2 headers and two Aura RGB headers enable synchronised RGB lighting through Aura Sync. The board ships with ASUS 5X Protection III safeguards including DIGI+ VRM, LANGuard, SafeSlot Core+, overvoltage protection, and a stainless-steel back I/O shield. UEFI AMI BIOS (192 Mb Flash ROM) with EZ Mode, CrashFree BIOS 3, and EZ Flash 3 is included. Bundled accessories include two SATA cables, an I/O shield, an M.2 rubber package, and two M.2 screw packages. Supported operating systems are Windows 11 and Windows 10 64-bit. The product carries a 3-year warranty.
