Good budget board

Pros: Looks good and I have never had any trouble with this brand. Not sure if good for OC but my gaming pro carbon ac is good for that but it cost more than this one. It runs cool and worked out of the box with 2600 and M.2 drive.

Cons: Software is not that great.

Reasonable AM4 budget MB

Pros: - carefully build (as all MSI products)
- USB type C available

- great BIOS, lots of possibilities for OC,

Cons: - if you know what you have ordered there should be no cons

Overall Review: - maybe the lack of a 3rd sys fan connection but considering that it is micro ATX and it will go to a small case two of them are more almost enough

Mostly great board

Pros: - I found it surprisingly difficult to find a black and red colored board considering that they go with AMD (team red).
- It will be interesting to see what happens to the prices of B450 and X470 boards when the 500s become mainstream, but it is worth the $100 as of a month before Zen 2.
- Speaking of Ryzen 3000. MSI confirmed that basically all their boards will be Zen 2 compatible. So if you want something now with an inevitable upgrade to a next gen processor you're good.

Cons: - I/O looks a bit out of place with the black/red theme of the board. I would like to see a one piece I/O cover and shield become standard.
- USB connectors would have a better home on the rear of the board rather than the bottom. If your case has shorter front panel cables this could become a problem when trying to cable manage.
- The PCIe slots are odd to work with. The 3.0 is mostly fine. You may run into an issue with an overly thick graphics card, but most cards will not have an issue. You will, however, have an issue if you plan to use the 2.0 slots. Any graphics card will cover the first of the 2 slots, and most graphics cards will cover go right up to the second. So if you can fit say a USB or sound card in there it will be choking your GPU fan. Even without a discrete GPU the second of the 2.0 slots is right next to the fan and USB jumper connections. Any thickness on the device you use, lets say a capture card, and you will be covering those connections, and at the very least increasing the likelihood of crimping any wires plugged in to them. More likely though is that if you have something plugged into the USB headers, like your front panel cables, the second 2.0 slot is rendered useless. Personal opinion: the PCIe 2.0 slots are a waste on this board. I want one for use with my capture card, but I just don't see where it would fit without being hazardous to some other component.

Overall Review: - I don't regret this purchase. It matches well in my with my black and red build, and all the features needed for a "quality build on a budget" are there.
- I can't speak on the fan connections aside from them working. The case I got had fans with 4-pin and molex connectors on them, and I opted to use the molex just so that I could hide them. Not the boards fault.

Nice, Simple, and Elegant MOBO

Pros: - Easy to setup. I might be biased since lately I prefer a more smaller scaled build so this micro MOBO just fits my fancy.
- Aesthetic wise, this MOBO is simple, but quite elegant.

Cons: - Nothing at the moment.

True simplicity is beautiful

Pros: Everything fits nice physically. The board is thin enough that the I/O shield was able to stay in place when lowering it onto the standoffs in a very narrow space. Installed a Noctua NH-U9S cpu cooler with no problems and the wide brackets had plenty of room around the cpu socket. M.2 slot is raised above and away from the video card and exposed to nice airflow if you have a side panel case fan. Running two 120mm and three 92mm fans (including the push/pull combo on my processor) using two splitters, all PWM.

The click bios is powerful (with UEFI option) after you turn on advanced mode and it was easy to setup my memory in an XMP profile at 3200Mhz. I like the built in fan controls (upgrading from a 970A with software controls in win7). Also has a button for "turbo" mode that overclocks the CPU by 450Mhz, although this seems kind of redundant with the Ryzen master utility nowadays.

Cons: The only thing I could think of is that it only has two RAM slots, but I won't need more than the 16Gb I put in for a long time.

Overall Review: Installed this with a Ryzen 5 2600 and Sapphire Pulse RX570 (which seems sturdy in place with the reinforced PCI-E slot) and dual channel G.Skill FlareX cl16, in a Fractal Core1100 case.
