Socket and generation support

This ASUS ROG Strix motherboard uses the Intel LGA 1700 socket and the Z790 chipset. It accepts 12th, 13th and 14th Gen Intel Core processors as well as Pentium Gold and Celeron CPUs. A BIOS update may be required for some 14th Gen chips.

Memory type and capacity

The board provides four 288‑pin DDR4 slots running in dual‑channel mode. Supported speeds range from 2133 MT/s up to 5333 MT/s when overclocked, with a maximum capacity of 128 GB.

Storage layout and networking

Four M.2 slots and four SATA 6 Gb/s ports give plenty of drive options, all operating over PCIe 4.0 from the CPU or chipset. Networking includes Wi‑Fi 6E and Intel 2.5 Gb Ethernet, plus USB 3.2 Gen 2x2 Type‑C with 30 W Power Delivery on the rear I/O.

Questions about this item

What does the 16+1 power-stage design rated at 70A per stage mean for a multi-core processor?

The 16+1 power stages each rated at 70A deliver stable current to high-core-count 12th, 13th and 14th Gen Intel Core CPUs, while dual ProCool II connectors, alloy chokes and durable capacitors keep voltage steady under heavy multi-threaded loads.

How does the PCIe 5.0 x16 slot and the four PCIe 4.0 M.2 slots limit GPU and SSD bandwidth in practice?

The single PCIe 5.0 x16 SafeSlot runs at full 5.0 speed with 12th-14th Gen CPUs, while all four M.2 slots operate at PCIe 4.0 x4 — M.2_1 supports 22110 length with heatsink and backplate, M.2_2 and M.2_3 take 2280 drives with heatsinks, and M.2_4 also supports 2280.

What case clearance and mounting points does the ATX board with massive VRM heatsinks and integrated I/O cover need?

The board follows standard ATX mounting holes; the large VRM heatsinks with integrated I/O cover and high-conductivity thermal pads add height above the socket area, so verify CPU-cooler clearance, and the front-panel USB 3.2 Gen 2x2 Type-C connector with PD 3.0 up to 30W requires a matching case header.
