Thomas B. Used for: 6–12 months
Cons
Wi-Fi antenna connector works loose over time
Comment
Board has been solid for eight months but I have had to reseat the aerial twice after the connection went flaky, which is not something I have had to do on any previous build.
Daisy B. Used for: More than a year
Pros
Has run flawlessly for well over a year
Comment
Long term this has been a good buy. No failed posts, no lost settings after a firmware update, and no thermal drama at all with a 9700X under it through two summers.
Oscar N. Used for: More than a year
Comment
Over a year in and still doing everything I ask of it without complaint
Ella C. Used for: 1–3 months
Pros
Fast Wi-Fi, cool VRM, tidy cable placement
Cons
The lighting software is bloated and wants to run at startup
Comment
Two months of daily use and the hardware side is genuinely excellent. What lets it down is the software. To control the board lighting you install a suite that pulls in a service, an updater and a launcher, all of which want to start with Windows, and none of which can be removed individually. I ended up setting a static colour in the BIOS and uninstalling the lot, which works, but I paid for lighting control I now cannot use properly.
Charlie C. Used for: 1–3 months
Pros
WiFi 7 and a clean layout
Comment
Connected to a WiFi 7 router and getting speeds I did not think were possible without running a cable. Layout is tidy and the M.2 covers come off without tools.
