Good Value Matx board

5 September 2019
Has everything you need - Matx means of course fewer PCI slots. But 2 x m.2 is nice, the 2nd m.2 is a sata m.2,.Uisng an nvme m.2 for boot, and a SATA m.2 for apps, this makes for a very clean build, no drive cables for the win! Overclocks ok, not sure how it would go with an 8 core + CPU, but no issues overclocking a 3600.

The RGB is okay, im not a huge fan of RGB, but thta is personal taste.

Came with Zen2 bios ( Ryzen 3XXX ) already loaded.

Best value B450 Ryzen board on the market - when on sale

26 August 2019
The features on this M-ATX board will rival many X470 boards. Bought this with Ryzen 2600 and 16GB Ballistic RAM 2666MHz CL16

I'd recommend this M-ATX board over the Full ATX version. The extra you pay for the full ATX and what you get for the extra money...it does not compute in my math. Unless you absolutely need more PCIe slots, then its cool.

Pros:

Can overclock you Ryzen chips (your mileage will vary depending on your chip and silicon lottery)

Decent amount of connectivity for this price range. It's best to buy these when on sale.

RGB heads and onboard RGB. (this ccan be disabled in Bios)

Bios is simple

4 x DIMM sl...

Good features for the price

23 August 2019
Probably the best b450 board out there right now, recognised my 3600 right out the gate. Seems to be reliable so far, hasn't kicked up any issues a month into use. Has a ton of modern features and plenty of pwm headers. Only complaints would be that the vrm is a bit average and the 'rgb' on the board is just fixed rainbow colours as far as i can tell. Audio is a bit weak power wise too.

Win 7 Upgrade (It can be done)

15 August 2019
If you are upgrading from WIn 10 To Win 10 on this motherboard then its a 4/5 stars. This MOBO loses 1 star for backwards compatibility issues. On Win 7 you DO NOT have USB support. If you are upgrading from WIn 7 to Win 10 then you have to do this. 1) Have a native PS/2 keyboard (a PS/2 mouse won't work) and an internal DVD/CD drive 2) Set the BIOS to legendary.3) Use the support DVD/CD that comes with the MOBO. 4) Navigate using the keyboard to the DVD/CD drive and load the all the drivers. You should now have USB Keyboard/Mouse access now. This board also lost 1 star due to the fact it has only 1 PS/2 port and other BIOS issues. If it's...

Best B450M Motherboard
