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!

Rated 5 out of 5 by from Best VRAM in the B450 series Heat sinks and VRAM help keep this bad boy nice and cool even when overclocked with a Ryzen 2700X. Finished my PC build and now works like a beast

Rated 5 out of 5 by from Good board, bios already updated After building a pretty much new PC (specs below), I went to update the BIOS to make sure I didnt have any compatibility issues with NVMe, Ryzen 3600 etc etc., neednt have bothered as it was already the latest. So far, the board has performed as expected, the BIOS menu is easy to use. A few points: - Turned XMP on - worked fine, running at 3200Mhz as per mem specs - checked with CPU-Z - NVMe running to spec - checked with CrystalDiskMark - Fan profiles changed in bios for system and cpu fans - quiet for web surfing, full blast for gaming, linked to CPU load. - I would NOT recommend installing MSI Dragon Centre, caused me all sorts of problems as it kept resetting all sorts of settings without me instructing it too. - It is not advisable to use 'Gaming' mode which can be set in the BIOS or dragon centre - not first hand experience but you can unknowingly 'cook' your CPU reducing its lifespan. - Benchmarked my setup and am getting top 5-15th percentile on 3DMark (Firestrike and Time Spy). CPU running hot at stock under benchmark loads so will exchange the stock AMD cooler (not the MB's fault though).

Questions & Answers

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

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 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!
