ASUS Prime B365M-A DDR4 Intel Motherboard

The ASUS Prime B365M-A is a Micro-ATX motherboard built on Intel's B365 chipset, designed for Intel LGA1151 socket processors from the 8th and 9th generation — including Core i7, Core i5, Core i3, Pentium, and Celeron families running on Intel's 14nm process. Its compact 9.6 x 8.6-inch (24.4 x 21.8 cm) mATX footprint makes it well suited to space-conscious desktop builds without sacrificing expandability. Memory support spans four DIMM slots capable of holding up to 64GB of DDR4 RAM running at 2666, 2400, or 2133 MHz (Non-ECC, unbuffered) in a dual-channel configuration. The board also supports Intel Extreme Memory Profile (XMP) and Intel Optane Memory modules to accelerate attached storage and shorten boot times. Storage is handled by two M.2 Socket 3 (M-key, 2242/2260/2280) slots — one supporting both SATA and PCIe 3.0 x4 modes, the second PCIe 3.0 x4 only — delivering up to 32 Gb/s transfer speeds, alongside six SATA 6Gb/s ports with RAID 0/1/5/10 support via Intel Rapid Storage Technology. Connectivity on the rear panel includes HDMI 1.4b (up to 4096×2160 @ 30 Hz), DVI-D (up to 1920×1200 @ 60 Hz), D-Sub (up to 1920×1200 @ 60 Hz), one USB 3.1 Gen 1 Type-C, four USB 3.1 Gen 1 Type-A ports, a Gigabit LAN port (Realtek RTL8111H), PS/2 keyboard and mouse ports, and an 8-channel audio stack. Internal headers add two further USB 3.1 Gen 1 ports and four USB 2.0 ports. Audio is powered by a Realtek ALC887 8-channel HD Audio CODEC with audio shielding, dedicated PCB layers for left and right channels, and Japanese audio capacitors. ASUS Aura Sync is supported via a dedicated onboard RGB strip header. Protection features fall under ASUS 5X Protection III: SafeSlot Core (reinforced PCIe x16 slot), LANGuard (surge/lightning/ESD protection), Overvoltage Protection, Stainless-Steel Back I/O, and DIGI+ VRM. Thermal management is handled passively (fanless heatsink) and via Fan Xpert 2+ software, with one CPU fan header and two chassis fan headers. The UEFI AMI BIOS supports ASUS EZ Flash 3, CrashFree BIOS 3, and EZ Mode navigation. Warranty is 3 years.
