Graet Board 2/16/2020 6:19:38 AM

Pros: Makes Ryzen chip most reliable

Cons: The box was wet but the board was dry, the delivery box did not seem to be wet. Missing speaker buzzer, which I do not use anyway.

Overall Review: I have purchased two of thees and use the m.2 slot which knocks out 5 and 6 sata ports so if you need more make sure to order an extra sata card.

Not Reliable 2/13/2020 12:35:59 PM

Pros: None

Cons: 1st one DOA.
2nd one DOA.

Overall Review: I have been building PC's since the days of 286's, so it is not my inexperience. Components these days are just mediocre at best. Look around, look at reviews. Very high dissatisfaction industry wide. Now, not only do I have junk I cannot get my money back on, I have to dispose of it. I can't just throw it in the trash. Maybe I should box it up and mail it back to Newegg? Buyer beware.

Dear Matt,

Thank you for sharing your experience with the MSI B450 TOMAHAWK MAX motherboard. We certainly value your feedback and please accept our sincerest apologies for any inconvenience you have experienced. Please make sure you are installing a compatible CPU on the motherboard. We recommend double-checking all power connectors are fully seated. This includes the 24-pin Motherboard power connector and the 4+4-pin CPU power connector. Once you have ensured that the connectors are fully seated, we recommend booting with a bare configuration, which means only the CPU, motherboard, power connectors, and a single stick of RAM. If this does not work, we would advise testing the power supply using either the "Paper Clip Test" or testing it on a secondary PC. Lastly, you can also attempt to build the motherboard outside of the case to prevent any potential grounding issues. If you have any further questions regarding this product or have any suggestions for improvement for us, please do not hesitate to contact us directly at usrma@msi.com and we will be more than happy to assist you. If you require further technical assistance, please feel free to contact our technical support department directly at 626.271.1004 from M to F, 9am to 6pm Pacific Standard Time.

Thanks for choosing MSI!

Excellent board 2/11/2020 6:52:52 PM

Pros: Easy to setup
EXCELLENT instruction manual

Cons: Ryzen 5 3600 Wraith Cooler fan INTERFERES with the A1 memory slot, fan supposedly must be rotated, although I haven't tried this yet.

Overall Review: Affordable for a modest PC build.
It would be nice if information on how to rotate the CPU fan was included in the manual, since the board is advertised to people with AM4 processors.

Rock solid motherboard 2/10/2020 6:02:51 PM

Pros: Bought this for my Ryzen 3600x and it was a wise purchase slapped in the processor and ram and everything worked perfectly with no hassle read my 3600mhz G Skill ram with the XMP profile has addressable rgb lights on the top right side of the motherboard while i cant test it according to reviewers the vrm cooling is superb so this should last a long time.

Cons: Sadly the first motherboard came DOA for anyone that might scare off don't worry it can happen from time to time thankfully newegg and msi stood by there products and customers and exchanged it with no hassle.

Overall Review: Would buy from them again amazing motherboard and for anyone looking to drop ryzen into look no further than this.

Post Problems and OS Shutdown Problem 2/10/2020 1:55:33 PM

Cons: No boot
OS shutdown problem
Frequent crashes

Overall Review: Since I got the board and booted for the first time it was iffy. Sometimes it would boot other times it would try then quit. I went to latest bios startup didn’t improve. I got a beta bios from MSI and it caused my board to not even begin to boot. This was a terrible experience. Terrible board would not recommend.

This MoBo made the build easy, and the PC is FAST 2/8/2020 8:26:19 AM

Pros: Easiest RAM seating I have ever experienced.
CPU/Heatsink (screws, not clips) was also very easy, compared to some past builds.
MoBo has everything my wife needs and nothing she doesn't.
BIOS and User Manual both have some "learning curve" but this is the first MSI board I've tried. It will not be the last!

Cons: None at this time.

Overall Review: I was able to build a system better than MaximumPC's mid-level system (bigger SDD & HDD, better-spec'd PSU, twice the RAM) -- for the same price.
I'm happy.
