Review: Excellent budget motherboard with nice io - My ryzen 5600 worked straight out the box! Had to get this one due to the board I was originally getting didn’t have next day. Therefore ordered this instead. Was surprised to see it was ryzen 5000 ready with a sticker showing on the box. Was prepared to use the built in bios flash back. Nice to have all usb 3 / 3.2 ports on the back. And the addition of NVME drives. Which I will be getting soon. Really simple board to wire up and was fun to move to amd after using intel for years. Will enjoy this board until I need to upgrade my 1070 in the coming year or 2 which will be replaced for one with PCI-E Gen 4 to maximise performance for a newer GPU 5 stars all day.

### ⭐⭐⭐⭐ Great! but a few minor issues
*by C***Y on 20 March 2024*

motherboard works extremely well and is great value for money, but when you plug in the gpu it is not easy to plug in my wifi card. one slot is completely blocked off and the other when the card is in presses against my cpu. but apart from that, this board has amaxing value
