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 for the Price
For a standard PC setup, this does the job brilliantly. I paired this with an AMD Ryzen 5600G, a Samsung 970 Evo Plus SSD, and it gives good performance for every-day use and acceptable performance on some of the earlier C.O.D. games. Do note however that if you have a case with more than two case fans you will have to buy a splitter, as there is provision for only 2 case fans (and 1 cpu fan). Fittimng of the AMD processor was not as straightforward as an intel equivalent, requiring access to the rear of the motherboard and the use of screws. So make sure you fit the processor before you install the motherboard in your case. In summary, a good motherboard at a good price.

Sturdy and relatively cheap
Good value for money if you want a cheap MB that does just that. It's quite sturdy and easy to install if you follow the instructions. Got decent ports at the back.

Faulty Motherboard - Avoid purchasing Like New computer components
I have been purchasing components from Amazon for quite a number of years and this motherboard ranks as the worst buy I have ever made. When taking delivery of the item, immediately noticed that there was was no brown outer packaging, just the Asus box with the motherboard inside. From immediate first impressions the box itself looked as if it had seen better days and did not look like a 'Like New' item at all. Opened the box up and the plastic bag containing the motherboard was caked in thermal paste as was the board itself. Screws were missing and the instruction manuals looked tatty. This product looked like it had already been previously returned by an unhappy customer and now sold on again. My suspicions were confirmed after piecing the components together. When fitting a new Ryzen 5 processor and heatsink to the motherboard, two of the screws of both retention arms were difficult to prize off. One of the screws was completely threaded and had to use a specialist tool to carefully remove it. That was a bad sign as was noticing that a pin on one of the sockets was bent. After putting everything together, there was no video output. Tried two different and compatible graphics cards and there was no output on the screen, plus an orange warning light appeared near to where the Graphics card was seated. This usually indicates a RAM issue, but the RAM was new out of the box and checked all the fittings accordingly. After four hours, gave up the ghost and disassembled everything. Minded to return what was a new processor which was awkward to uncouple from the heatsink and board, and now just hoping that it was not damaged in the process. Overall, the moral of the story is be careful what you wish for when buying Like New computer components and always buy brand new products. Will be returning this item and hopefully getting a refund. Very disappointed with the seller for allowing defective goods like this to be recycled and sold on to other consumers, hence the one star and four hours of my life that I will never get back

I was looking for a cheap motherboard which is very difficult to find now a days. I am using it with Ryzen APU 3400G, 16 GB DDR 4 3200 Hz ram. Its Micro Atx with 4 ram slots, has all feature to support OC. Wifi is not built it but you can buy a PCIe card and install it.
