Rated 5 out of 5 by from Great MOBO on my first build This was my first build and after as lot of research I took the plunge and went with this MOBO. It arrived quickly and very well packaged, it was reasonably priced and Scan updated me regularly. It was very easy to install and install the various Peripherals were easy tom stall on the MOBO. The manual was clear and concise making the build much easier Highly recommended

Rated 5 out of 5 by from Quality product It may not be in the top end list of Motherboards but it certainly can hold its own with what you get for the money. The minute you unpack it, you can see the quality and it doesn't disappoint.

Rated 5 out of 5 by from For the Price this Mobo is a Monster Have done my research and wanted a very good mobo for my new Ryzen 3700x and have noticed that the new X570 boards are way to expensive and not as good as this Monster for the price. This mobo is actually an upgrade from its predecessor which supports the new Ryzen 3 chips straight out of the box. Which also comes with an upgraded Bios software which is very nice. Also comes with a fancy RBG lights which you can setup as you wish. If your looking for a great mobo for the new Ryzen 3 chips and do not want to spend a fortune for a mediocre X570 board then this board here is for you. I think MSI has done a great job on this product. I would highly recommend this Board.

Rated 5 out of 5 by from One of the best motherboards from B450 series One of the best motherboards from B450 series so far! It comes out of the box and already compactible with 3nd ryzen processors! Price is really good for that kind of motherboard. I always choose MSI products if I can, and never was dissapointed. If you need good motherboard, with good VRAM, affordable price, and compactible with 3rd ryzen processors, get this one!

Rated 5 out of 5 by from Excellent MB for Ubuntu install - Win7 forget it! Really smooth install of Ubuntu and Debian systems - took Ubuntu Studio 19.10 with no problems, low latency kernel quite happy. Windows 7 was a disaster though - endless loops of updates to drivers, and after a day and a half I gave up. Probably a bit optimistic to try such an old-world O/S on a modern board, but I refuse to go down the spyware rabbit hole wihich is Win 10. Really happy with the board!

What BIOS version ships with this Board? I'm looking to pair it with a 3600X and it requires a recent BIOS version for the 3000 series to be supported

Asked by: ST44RK7
Bought this board a few weeks ago and it shipped with the latest BIOS: 7C02v35.

Can I have a ssd installed straight onto the motherboard if so where?
Asked by: Ethan8273
You know the answer to this. You can fit a M2 SSD onto the board, MP510 980GB works flawlessly.

Will this fit a M.2 PCIe 3.0 x4 NVMe SSD 2280
Asked by: Ethan8273
You will lose two SATA ports if you go that route - just be aware! Double check with the MSI site for a list of compatible SSDs.

what would be a good comapatible gpu for this mobo?

I'm new to pc builds so I don't want to buy the wrong stuff, which I have already learnt is easily done
Asked by: PoPeYeXC
Depends what you want to do, and how much you want to spend. Any nVidia or AMD GPU will do a grand job, and some of the AMD processors include on-board graphics - so this https://www.scan.co.uk/products/amd-ryzen-3-3200g-w-radeon-rx-vega-8-graphics-am4-zenplus-quad-core-4-thread-36ghz-40ghz-turbo-4mb-6 would do the job for not too much cash. I run an MSI AMD 580 GPU on the board, works without a hitch, and gives me up to 120 fps in X-Plane (my gaming weakness...) which is superb! If you went that road, it would cost you £170 for the CPU (Ryzen 5 3600, scan code LN99201) plus £160 for a GPU (Asus 580 board, scan code LN105692). So you really need to know what you want to do with the system before choosing! A word of caution - if you go for the on-board NVME solid-state drive option, you will lose two channels for SATA drives. In my case, I need all 6 SATA slots so I went for a single SSD as my operating system drive, and used the rest for DVD drive and RAID array etc. Blue skies - keep safe!
