      Designed for 9th generation Intel® Core™ processors, the Prime Z390-A delivers maximum performance with customizable style. 5-Way Optimization provides AI overclocking and dynamic fan calibration while dual M.2 and USB 3.1 Gen2 delivers maximum transfer speeds. Aura Sync RGB with addressable headers customize your build. The overclocking module of AI Suite's 5-Way Optimization has been revamped for the Z390 platform. This new version quickly delivers overclocking results that would typically take days of manual tuning. With x4 PCI Express 3.0/2.0 bandwidth, M.2 supports up to 32Gbps data-transfer speeds. Also, with backward compatible USB 3.1 Gen 2 Type-A and reversible USB 3.1 Gen 2 Type-C ports, you'll experience ultimate connection flexability and blazing data-transfer speeds of up to 10Gbps. With Fan Xpert 4 you can map the temperature of supported ASUS graphics cards to optimize cooling for GPU and CPU-intensive tasks. ASUS Aura offers full RGB lighting control with a variety of functional presets for the built-in RGB LEDs as well as strips connected to the onboard RGB headers. And it can all be synced with an ever-growing portfolio of Aura-capable ASUS hardware.

      Great motherboard
      This is my 4th asus motherboard. Built 4 computers and loved them all. I overclocked this one to 5.0ghz. Asus makes the best.
      By anonymous shopper
      No socket cover
      Was shipped without socket cover, missing the io shield, missing manual. Kind of disappointed.
      By Edward Jackson
      Buy this motherboard, all the others just cost to much.
      I just got done with a z370-g(worst asus motherboard ever made, i have many reasons why) this motherboard runs the way i think that asus mobo’s should. Everything works great.
      By Janina Hardenberg
      Horrible support
      Dont expect asus to go above and beyond.. Or even to do what is expected from a tech company. Purchased mine during a promotional period only to receive a faulty mobo. This happens and i understand so i had to send it back and get a new board. During this transit time the promo had ended and asus will not honor it. When i called to help troubleshoot the doa i was expected to setup a complete test bench by asus to do my own troubleshooting. Told i had to send pictures of components to prove im using what i was. Great motherboard, just dont expect much help if something doesnt work. Asus used to be a very reputable company... Now they're a joke. If you can go msi or gigabyte.
      By Mackenzie Wright
      Windows 10 had me like what?
      Pretty sure these motherboards are made with windows 10 requirements. Previously running windows 7 happily..... After switching out the board, processor, memory i was given nothing but trouble in order to install windows 7 and still was unable to operate the mouse and keyboard to install it.... Went out $300 for windows 10 only to find zero issues with the install at all!?! It isn’t an outletpc issues, or even a technical issue, my feeling is that it has something to do with intel being pressured by windows to lock down the new genetation of windows. Long story short.... Windows 10 is working perfectly with no issues... But i wish it wouldn’t have been so much of a headache to get this motherboard to work. Hope this helps other users figure out which issues they may have when moving into the new generation of intel processors.
