LGA 1200 Intel Z490 ATX Motherboard
The ASUS Prime Z490-A supports 10th and 11th generation Intel Core processors in the LGA 1200 socket. It provides four DDR4 memory slots with a maximum capacity of 128 GB running in dual-channel mode. The board targets builders who need a full-size ATX platform with robust 12+2 DrMOS power delivery and comprehensive cooling for sustained workloads.
PCIe 3.0 and SATA 6Gb/s Interface Limits
Three PCI Express 3.0 x16 slots handle graphics and add-in cards at the speeds defined by the 3.0 specification. Six SATA 6Gb/s ports connect traditional drives, while two M.2 sockets accept storage modules without guaranteeing a specific protocol. The onboard Intel 2.5 Gb Ethernet controller is limited to 1 Gbps maximum throughput as stated in the specifications.
128 GB DDR4 2666 Maximum Memory Capacity
The four 288-pin slots accept DDR4 modules up to a combined 128 GB at the standard 2666 MT/s rate. This ceiling determines whether the board suits memory-intensive tasks such as content creation or virtualization. Exceeding this limit is not possible, so buyers planning larger memory configurations must select a different platform.

คำถามเกี่ยวกับสินค้านี้
Which memory kit should I pick for the four DDR4 288-pin slots?
The board runs four DDR4 slots in dual-channel mode up to 2666 MT/s and supports a total of 128 GB, so a matched 4-module kit rated at 2666 or higher will fill every slot and run at the rated speed with XMP enabled.
What does the 12+2 DrMOS power-stage design deliver for a 10th or 11th Gen Core i9?
The 14 DrMOS stages feed the CPU through ProCool connectors on a six-layer PCB, giving clean, stable current for sustained all-core turbo on flagship 1200-socket processors without throttling.
How fast is the onboard 2.5 Gb Ethernet compared with the 1 Gb RJ-45 port listed in the specs?
The Intel 2.5 Gb controller provides up to 2.5 Gbps throughput over the single RJ-45 jack, so real-world file transfers can exceed the 1 Gbps ceiling of standard Gigabit LAN when paired with a 2.5 Gb switch or router.
