Rated 5 out of 5 by from MSI Tomahawk max I've been looking into upgrading my pc for a while now, have a few friends big into gaming/pc building whereas I don't know so much. I thought replacing the main motherboard would be a really difficult job and then re-attaching all the new parts to it and getting everything in the correct place - how wrong was I. This MSI motherboard comes with all the info you need to know, really easy to follow instructions and now I'm thinking how could you get it wrong. Seriously really easy, great spec and a brilliant price! Buy one you won't regret it.

Rated 5 out of 5 by from Great Motherboard A great motherboard, looks good too, feels really durable and well put together. Super easy to attach the stock AMD CPU cooler to and the Bios is really easy to get around. Ontop of that, the instruction book is actually usefull for locating all the pins to connect front panel peripherals to, even if they are positioned about as far away from the front panel as you can get.

Rated 5 out of 5 by from Excellent Value for Money! I usually upgrade my PC every 12 months, and I generally spend a few weeks looking at reviews and feedback or products before I buy them. After reading hundreds of articles, I eventually decided on the MSI Tomahawk Max for my Ryzen 3600X build. I was originally looking at the more premium MSI X570 Gaming Carbon, however the price difference is big, and the features on the Tomahawk are more than enough for my needs at the moment. I don't usually cut costs on motherboards, my last couple of boards have been close to the £200 mark, however this time around my budget was a little lower than usual. First impressions are that this is much more premium board than its £90 price tag would imply. The packaging is solid, the board is well protected inside, there's a decent manual, a CD with drivers (although I feel a USB key would better these days) and the board itself looks great. I didn't want a fancy RGB board as I was looking to keep costs down for this build. There is some LED lighting on the Tomahawk - but not too much, so if that's what you're looking for, maybe look at something else in the MSI range. The board itself is a sleek gunmetal grey colour, with some nice chunky heatsinks. It looks very 'military', which is in keeping with the product being named after the Tomahawk missile. Connectivity is good - 6 SATA connections, plenty of system fan points, and M.2 socket which is important to me as that's where I'll be running my games from. My system contains 3 x SSD, 1 x mechanical drive and an M.2 drive, it's not in a large case, and yet I found the motherboard very easy to work with - it's very well-spaced out, and the important connectors are situated in thoughtful places to allow for easy cable management. I'm using a Corsair H100i for CPU cooling and it fits beautifully on the board - the pre-installed cooler mounts are perfect for it. On the rear I/O panel there's a Flash BIOS button which is a great addition (it saved the day earlier today!). The BIOS itself is really good as well - A full-featured GUI with decent overclocking options. For me personally, the product's strengths are: Decent layout Great connectivity Well priced Good looks If I had to pick one criticism, it's that the 4 x SATA ports could be moved a bit lower. My graphics card (Radeon RX 5700 XT) pushes down on them, as a result I had to unplug 2 of them and move them to the 2 sockets at the bottom of the board because the RX 5700 was causing them to drop out. However, this was only a minor niggle for me. I did have some trouble flashing the BIOS today - it repeatedly froze on a blank screen after flashing. I reset a few times and no joy, however the Flash BIOS button on the board rescued things! Using the button and a USB stick, I was able to roll back to a previous BIOS version and everything was fine. I would highly recommend this motherboard to anyone looking to build a Ryzen system on a budget. You really won't be disappointed.

Rated 5 out of 5 by from Excellent motherboard overall Really good quality and the motherboard is really easy to use. Supports all the new generation AMD CPU's. Would totally recommend for any budget or high end build.
Date published: 2019-12-28
Rated 5 out of 5 by from Great and nicely priced board I don't know a whole lot about building pc's but built my first 2 using these and alongside a 5700xt and ryzen 3600 I can say world of warcraft looks fantastic and I'm sure many other games would look good with it too.
Date published: 2019-12-24
Rated 4 out of 5 by from This product is great The product is easy to set up and runs very well with my graphic card. It allows me to play the games I enjoy playing.
