The Gigabyte Z890 Eagle motherboard provides four DDR5 slots populated to the 192GB maximum, leaving no free slots for expansion. It offers four M.2 connectors and four SATA 6Gb/s ports with RAID 0, 1, 5 and 10 support. Rear I/O includes USB4 Type-C, USB 3.2 Gen 2, USB 3.2 Gen 1 and USB 2.0 ports alongside Intel 2.5Gb Ethernet and Wi-Fi 7.

Pre-order checklist

Verify that the 360mm liquid cooler and full-size RTX 5080 fit your intended case clearance and power-cable routing. The 1000W 80 PLUS Gold PSU uses a 140mm fan and standard ATX connectors. Confirm your monitor inputs match the GPU outputs and that your desk space accommodates the 447 x 215 x 469 mm chassis.
