Amazing product

Pros: -All black color scheme should match any build aesthetic
-Built in wifi
-Lights look great without being overwhelming
-Lots of headers and ports, more than I ended up needing
-Solid build quality, feels well made
-Compatible with the ram i purchased
-Great heatsinks for what I need
-Bios were super easy to use

Cons: -I got lucky and was able to get one, but this board is rarely in stock from what I've seen
-Shield for M.2 a little confusing to use, instructions weren't too clear (or maybe it was just me)
-Had to split hairs for the cons, I personally couldn't love this board more!

Overall Review: I was looking for a solid b450 motherboard and saw a lot of people recommend this one so I went with it, and i could not be happier with my choice. It has everything I needed for mid level build, and even more. The board itself looks beautiful with a sleek black design, and the led lights are a nice subtle touch that is a welcome bonus. Card comes with wifi, so if you don't want to get a separate wifi adapter like me then this is perfect. Not much else to say, this board does its job perfectly and looks great too. Easily the best b450 board you can get in my opinion.

Works but...

Pros: Everything works.

Cons: Nothing.

Overall Review: Do you need a gpu for it to work. The Vga debug light turns on referring to that it’s missing or doesn’t have a signal to the gpu but if I don’t have a gpu does it just not work at all. Nothing shows up on the or anything.

Thank you for your review of the B450 Gaming Pro Carbon AC!

Amazing Board! The best B450 ever!

Pros: Easy to use and install
Good IO
BIOS flashback
Good Overclocking
RGB is cool
Wifi and Bluetooth
Lots of convenient features
Would totally buy again

Cons: None

Overall Review: The MSI B450 Gaming pro carbon ac is THE best B450 currently available to consumers. It has many premium features available, and all of these are very easy to use. I can OC my Ryzen 5 2600 to 2.9 Ghz no problem. The VRMs are amazing for overclocking. The M.2 Shield on the M.2 socket is nice for regulating SSD temps. The extra power connectors are nice, but my PSu doesn't have enough pins for that so can't test that. XMP is good, can get it up to 3200 MHZ. The RGB on this board is amazing. It syncs with my monitor, ram, and graphics card. No complaints there. BIOS is easy to navigate, EZ mode was helpful. If there was one thing ban about this, it would be that the Debug LEDs, while nice, are a bit harsh. Great motherboard! Would totally buy again! Highly recommended!

Working as directed

Pros: - The bios flash that you can do with a flash drive is REALLY handy. Worked first go.
- Easy bios configuration
- stable.
- lots of plugs for fans
- easy install
- pretty fast wireless (getting max speed through my cable modem at like 250mps)
- easy ram setup to 3200. (haven't tried OC'ing yet)

Cons: - Nice graphical bios doesn't work with 3700x bios

Overall Review: I built a new machine.

This motherboard, 3700x CPU, gtx 970 (will be upgrading to a 1080ti soonish), 32 gigs of ram, 1 TB crucial m2 drive (the slow one).

So far, it's solid as a rock, super fast, easy to set up.

I had the GPU in another machine with a core i7 2600k and this is a HUGE step up. Even with the same GPU, games are much smoother, I didn't bench but the 1% FPS on my 2600k was definitely an issue and now it seems like its really not an issue at all.

Games tried so far: Witcher 3, stellaris, civ6, DOTA. All run significantly better than before. Stellaris in particular seems like it runs so much faster it's basically a different game (i.e. playable at the end).

Great, when it works

Pros: - Nothing to complain about, has the slots available that I need, I'm not a number crunch kind of guy. The board runs well

Cons: - MSI was in no way prepared for the Ryzen 3000 series with their 4XX boards. 10 days after release I'm seeing every thread about this board and other MSI 4XX's being coin tosses to get running. CPU Debug Light is on and there's no consistent fix the internet has been able to find. All I can do is wait for a bios update. Won't be buying MSI boards again.

Overall Review: Disappointed / 10
