- Solid Supplier - Kyle, 25 April 2026
Left my review on Google, but I feel I didn't get enough in. Having the option for insurance built-in is an amazing stress-saver, and tends to work out cheaper for budgeters. Next upgrade is laptop RAM + an NVMe. You'll see me again ????
- No complaints - Donovan, 26 May 2025
Happy with the motherboard but one thing I didn't think to check is there are no headers for USB type-C. So if your case has type-C ports they won't work.
- Good features - Hugo, 27 March 2025
In a playback machine. 5600GT and RX6600 plugged in. Good performance. 4x dimm slots and two m.2's makes it a no brainier.
Enough heat sinks for the price as well. Should work excellently as a basic workstation motherboard if it has too. Just slap a 5700X or above and a decent GPU in and there you go. - Good Motherboard - Johan, 3 September 2021
Good motherboard and working very well paired with a Ryzen 5 5600G (no Graphics Card yet). I was surprised to see the motherboard already had the latest BIOS (was concerned that I may need to update for CPU support).
