Good mid-range mainboard. Easy system build.
5 Stars
Good mid-range mainboard. Easy system build.
Received MSI B450 Tomahawk AM4 on 1/19/2021 (a few days after placing order) and installed on 1/20/2021. Obviously, I have no data on durability. Also, I have had zero issues with the board, so no data on tech support. When assessing my Stability rating for this board, please understand that I do not overclock and only occasionally play computer games. When my old system failed (Asus board-six years old), I needed another stable and dependable mid-range system for productivity, web activity, and entertainment, including some gaming. My past system building experience has been with Asus mainboards, but the MSI board was the easiest system build I have ever done. I especially liked the placement of SATA1 and SATA2 connectors at bottom right corner of board for easy connection to hdds. My MSI board is AM4 socket, and I find AMD's (old-school) sockets and processors easier to manipulate than Intel parts. CPU cooler attached solidly to board, and I have had no cooling issues with cpu. I found board layout to be logical and easy to work with. My only complaint is with the flimsy metallic I/O port cover for the back panel connectors, but then I have never seen one of these that actually fit the mainboard properly. Components I'm using with my B450 Tomahawk include: AMD Ryzen 5 3600 cpu w/Wraith Spire cooler, Corsair Vengence LPX DDR4 memory, EVGA GEForce GTX 960 graphics card, Western Digital 1TB and 2TB hdds, EVGA 750W G2 Supernova power supply and Antec Nine Hundred case (see picture of running system). The remainder of my experience with this mainboard will consist of long-term evaluation. So far, I can attest that the MSI B450 Tomahawk mainboard installs easily with the hardware detailed above and has run Linux 20.04 LTS for about 36 hours now without any issue. Still early, but happy so far.
