Was great while it lasted 2/25/2020 4:39:54 PM

Pros: RGB Headers
A good amount of fan headers
Com port and 2 usb 2.0 headers
2 full sized PCI-E slots
Good price

Cons: It died.

Overall Review: We bought this board for a new workbench PC for our office. We got it to boot and messed around a little last week then didnt use it as we were busy with existing projects.
I went to boot it this week and it reported USB over current.
The only USB devices plugged into it was a mouse. The keyboard was using the PS2 port.
I changed power supplies and disconnected everything (including the front IO) from the mobo except the GPU. Still got the USB Over current error.
Time to RMA.

crashes constantly wont work with non MSI components 1/21/2020 11:38:49 AM

Pros: i was having a problem with this board crashing with a power color vega56 gpu and msi just said to use an msi gpu instead offered no help with problems I will never but an MSI microstar international product again and will never recommend one again.

the powercolor gpu and all other hardware is perfectly stable in an ASUS strix b350 f motherbord however.

Cons: it crashes and msi wont help figure out why even after 2 returns.

Overall Review: boooooooooo

Solid once it starts, but super slow to POST 12/26/2019 2:46:00 PM

Pros: Runs great once it gets started

Cons: Insanely slow to POST, even with the new BIOS (7B86vAC) that is supposed to speed up boot time. The Windows task manager reports POST times of 80-90 seconds (!!), and it takes about 180 seconds from pressing the power button until the Windows startup logo appears. It doesn't even manage to show any feedback for troubleshooting, in all that time it doesn't manage to get the monitor turned on. As soon as Windows boots, all the hardware runs fine, but something is very wrong in the startup sequence.

Overall Review: If I could get this motherboard to POST in under ten seconds, it'd be a definite buy. As is, I can't recommend it.

worked great for 1 year 1 week 12/4/2019 7:47:05 PM

Pros: It was an impressive value, features vs price was unbeatable

Cons: It only lasted 1 year and 1 week before failing. Too good to be true I guess.

Overall Review: I can't recommend something that doesn't last.

Pros: Excellent buy for the specs

Overall Review: Can't go wrong for this AMD chip series. A good buy with integrated graphics and an adequate cpu cooler provided.

Terrific board 9/27/2019 8:12:03 PM

Pros: OOB was very simple.
Clean layout with plenty of room for large fingers.
Lots of connection points.
Solidly built
Good quality components
No RGB on by default, thank you.

Cons: none

Overall Review: Straightforward set up and boot. A few simple clicks and the R5 1600 boosts up to 3.4 GHz with no issue at 35C. I used an Arctic Cooling Alpine 64 Pro which is rated to 90W TDP and once seated properly cool blowing air could be felt from the fan. The RAM I used was Team Force DDR4 3000 2 by 8 GB set that initially ran at 2400 but again a few simple clicks later was running tickety boo at 3000. I booted into HiRen and ran few simple tasks and everything responded as expected.

I haven't yet decided whether to do a rebuild or a from scratch install on this but then again I might try both, just for fun.

Setup was a breeze 9/26/2019 6:30:54 AM

Pros: XMP Profiles
M2 3 x 4.0 slot
Metal PCI-e slot

Overall Review: My first MSI board and setup went off without a hitch. Will definitely stick to MSI boards going forward. For the price of this board and everything that comes with it you can't beat it.
