Overview
The ASUS Prime Z390-P is an ATX-form-factor motherboard built around the Intel Z390 chipset and designed to support Intel's 8th and 9th generation Core, Pentium Gold, and Celeron processors via the LGA 1151 socket. Measuring 30.5 cm × 23.4 cm (12.0 in × 9.2 in), it fits standard mid-tower and full-tower cases while delivering a thoughtful balance of overclocking capability, connectivity, and protection features suited to enthusiast desktop builds. Memory support is a highlight: four DIMM slots accept up to 64 GB of non-ECC, unbuffered DDR4 in dual-channel configuration. Speeds range from native 2133/2400/2666 MHz up to DDR4-4266 via overclocking, with Intel XMP profile support. The OptiMem II trace-routing and ground-layer optimisation helps preserve signal integrity at elevated frequencies. Storage options are flexible. Two M.2 Socket 3 (M-key) slots support 2242/2260/2280 devices — the first running SATA or PCIe 3.0 ×4, the second SATA or PCIe 3.0 ×2 — complemented by four SATA 6 Gb/s ports. RAID 0, 1, 5, and 10 are supported via Intel Rapid Storage Technology, and the board is Intel Optane Memory Ready. Connectivity on the rear I/O panel includes one DisplayPort and one HDMI output (integrated graphics via Intel UHD), two USB 3.1 Gen 2 Type-A ports, four USB 3.1 Gen 1 Type-A ports, a Gigabit LAN port (Realtek RTL8111H with LANGuard surge protection), and three 8-channel audio jacks. An M.2 Key-E socket adds optional Wi-Fi/Bluetooth via an Intel CNVi or 2230 module (sold separately). Audio is handled by a Realtek ALC887 8-channel HD CODEC with dedicated PCB audio layers, audio shielding for analog/digital separation, and Japanese-made audio capacitors. The UEFI AMI BIOS (128 Mb Flash ROM) supports ACPI 6.1, SM BIOS 3.1, CrashFree BIOS 3, EZ Flash 3, and a searchable settings interface. ASUS 5X Protection III encompasses SafeSlot Core (reinforced PCIe slot), LANGuard, Overvoltage Protection, Stainless-Steel Back I/O, and a 9-phase DIGI+ VRM. Fan Xpert 4 provides PWM/DC fan and AIO pump control across the board's one CPU fan, two chassis fan, and one AIO pump headers.
