ASUS PRIME Z490-A Intel motherboard

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.
