It is FINALLY here 11/9/2019 9:56:00 PM

Pros: - Ryzen 3000 support right out of the box
- Lots of fan headers! I have seen X570 boards that only have 2 fan headers
- Color scheme works with any build (black/white themes work with any PC)
- As Buildzoid said, the B450 Tomahawk has quality VRMs
- Includes USB 3.2 Gen2 (Type A+C) ports
- Includes NVMe slot (haven't taken advantage of this yet)
- Ran Mystic Light to set RGB colors with no issues
- Includes a BIOS flash button (I didn't need it, but it is nice to have)
- Actually includes a paper manual - nice as I was only a second-time builder (my first build was an Intel Gigabyte board which did not include a manual)
- All the ports and RAM slots work with no problems
- Love MSI Update 6 (the ability to update the BIOS, drivers, and utilities without needing to hunt down which version of a file you need to update correctly - this program just automatically finds what you need for your PC - again, love this program)!

Cons: - Took forever to release in the USA (but it is finally here now)
- Cold boot issue with BIOS v33, no display on boot, BIOS v34 seems to have fixed the no display issue

Overall Review: PC Specs:

CPU: Ryzen 3700X
GPU: Zotac GTX 1060 6 GB
RAM: Crucial Ballistix 16GB 2400 MHz
HD: Crucial MX500 500 GB SSD

I could have purchased an X570 motherboard, but I went with the B450 Tomahawk Max. I needed a quality board for my gaming PC. I don't have fast Ryzen memory yet to test out. Waiting on Black Friday for that.

No regrets purchasing this motherboard, especially since a new update fixed the display issues. Just wished it was released sooner in the USA (I had been waiting since July for the Tomahawk Max to release).

Great value board 11/7/2019 7:53:07 PM

Pros: Mystic Light
12V RGB rails x2
Ryzen 3000 Ready
Great memory support

Cons: No 3v dARGB headers

Overall Review: Overall I think this board was a great solution from MSI for the Ryzen 3000 series chipset from AMD. I would have liked to have seen a bit more connectivity on the board for some additional RGB features such as a 3V Argb/Drgb rail for a bit more customization.

This board offered great value for 8/10 things I was looking for in a motherboard and is one of the main reasons why I chose it over more fancy x570 boards.

Perfect with Ryzen 3600 10/20/2019 11:42:51 AM

Pros: Very clean board
I upgraded to the latest BIOS (as of now, 7C02v33 with AMD ComboPI1.0.0.3abba) using the flash BIOS button before inserting the processor. It failed at first, and needed to reformat the USB key and put only the binary file on it.
The CPU voltage regulator heatsinks are barely warm, same for the chipset.
The build went smoothly, the resulting system is very stable on heavy continuous load (crunching for World Community grid in the background 24/7)
The feature called 'Memory try It!' made tweaking RAM settings easy.

Cons: I would have appreciated to get more USB ports, but I would certainly buy again, the predecessor (Tomahawk) is one of the most popular AMD 3000 MB for a reason

Overall Review: You can't go wrong with this board.
