Rosie G. Used for: Less than a month
Cons
The bundled fan extension card is another thing to find room for
Comment
Superb board, but the fan hub card has nowhere obvious to mount in my case and it came with no adhesive pads.
Charlie P. Used for: Less than a month
Pros
Every part of the build was easier than it should have been
Cons
It costs as much as a decent graphics card
Comment
This is my first build in a long time and I deliberately overspent on the board to make the rest easy, which turned out to be the right decision. The Q-Release button pops the graphics card out with one press. The M.2 drives clip in with no screws and the heatsinks come off with a latch. The front panel connector is one block. The BIOS flashback button meant the firmware was current before the processor came out of its packaging. Every one of those took a job that used to be fiddly and made it trivial. Electrically it has been perfect from the first boot, 6400 memory profile enabled, both drives detected, network up before Windows finished. Only the first few weeks so far, but nothing has wobbled. The only argument against it is money, and there is no getting round that.
Jack P. Used for: 6–12 months
Pros
Two USB4 ports, 10G LAN and the tidiest layout ASUS has done
Cons
Armoury Crate, again
Comment
Built around a 9950X3D for work that is half rendering and half gaming, and this has been the board that stopped me thinking about the platform. Memory training with 96GB took one attempt and has been instant on every cold boot since. The 10G port feeds a NAS at full speed, both USB4 ports drive displays and an enclosure at the same time, and the VRM has not been above 50 no matter what I run. That is most of a year now with no change in any of it. The software is still the weak point. Armoury Crate wants to own the machine, so I set the fan curves and the lighting in the firmware and left it off entirely.
