Since the "Comet Lake-S" processors require a new socket due to the optimized power supply, the Intel Socket LGA1200 is used on the 400 series mainboards. Despite the increased number of pins, the actual size of the socket remains the same with older sockets, so that CPU coolers for socket LGA 115x can also be mounted on the mainboard.
The features of the ASUS ROG Strix Z490-A gaming motherboard at a glance:

- 2x USB 3.1 (external, 1x Type A, 1x Type C)
- A total of 7x USB 3.0 (4x external / 3x internal) and 6x USB 2.0 (internal / external)
- 2x M.2 (1x PCIe 3.0 x4 / SATA & 1x PCIe 3.0 x4) / 6x SATA 6G
- Supports max. 128 GB DDR4 RAM up to 4,800 MHz
- Integrated RGB LED lighting including RGB LED headers

The ASUS ROG Strix Z490-A Gaming in detail
The ASUS ROG Strix Z490-A gaming motherboard in ATX form factor offers three PCIe-x16 slots, one PCIe-x4 slot and one PCIe-x1 slot for plug-in and expansion cards. An x16 slot is connected with a full 16 lanes, the second and third can share the 16 available lanes with the first. Another PCIe 3.0 x4 slot is connected with two lanes. As a high-end motherboard, the ASUS ROG Strix Z490-A Gaming also supports multi-GPU setups via AMD Crossfire / XDMA. Other features of the mainboard also include a striking cooler design and integrated RGB LED lighting. Three headers for RGB strips allow the connection of further RGB LED components.
Up to 128 GB DDR4 RAM in dual-channel mode can be used in the four DIMM slots. The Z490 chipset supports clock speeds up to 2,933 MHz, but the OC enables the ASUS ROG Strix Z490-A Gaming to operate RAM kits with up to 4,800 MHz! Two M.2 slots for PCIe / SATA-M.2 SSDs and six SATA-6G connections enable data storage media to be connected. Both M.2 slots are connected to the chipset with four PCIe lanes and support the NVMe protocol, which enables data transfer rates of just under 4 GB / s. This makes M.2 PCIe SSDs up to eight times faster than SATA 6G SSDs!
The ASUS ROG Strix Z490-E Gaming has a USB 3.1 port on the I / O panel with a Type-C socket. This innovative USB Type-C port is particularly thin and can be inserted on both sides. USB 3.1 or USB 3.1 Gen 2 achieves maximum speeds of 10 Gbit / s per port and USB ports with this standard generally support the quick charging function of smartphones and tablets. In addition to a further USB 3.1 port of type A as well as four USB 3.0 and two USB 2.0 ports, a 2.5 GBit LAN connection can also be found on the I / O panel. Internally, the mainboard provides a large selection of connections and headers.
