Full review

The ASUS Prime Z790-A is a full-ATX motherboard built for enthusiasts and builders who want a dependable foundation for high-performance Intel systems without stepping into flagship pricing. Designed around the Z790 chipset, it supports 13th and 12th Gen Intel Core processors, giving builders flexibility whether they're starting fresh or upgrading an existing LGA1700 setup. The board features a robust power delivery system with durable power stages, optimized thermal design, and a large heatsink array that helps maintain stable performance under sustained workloads, whether that means gaming marathons, content creation, or multitasking across demanding applications.

Connectivity and expansion are where the Prime Z790-A really shines for its class. It offers support for DDR5 memory with generous overclocking headroom, multiple PCIe 5.0 and 4.0 slots for graphics cards and NVMe SSDs, and PCIe Q-Release along with Q-Latch mechanisms that simplify component installation and removal. Rear I/O includes USB 3.2 Gen 2x2 Type-C, multiple USB 3.2 and 2.0 ports, and 2.5Gb Ethernet, ensuring builders have ample bandwidth for peripherals, external storage, and fast wired networking. Onboard features like BIOS FlashBack and Q-LED indicators make troubleshooting and firmware updates straightforward, even for those building their first PC.

Aesthetically, the Prime Z790-A leans into a clean, professional look with a mostly neutral color scheme, subtle styling, and PCB protection elements that reduce flex and extend longevity. Addressable RGB headers and Aura Sync compatibility allow for lighting customization without forcing a flashy design on users who prefer understated builds. Overall, this motherboard fits squarely into the mid-to-upper tier of the Z790 lineup, appealing to PC builders who want reliable power delivery, modern connectivity, and straightforward usability for custom builds centered on current-generation Intel CPUs.
