Bios and setting up fans and rgb not good. 8/26/2020 6:47:45 PM

Pros: WiFi, good availability of fan and rgb headers.

Cons: Bios is awful, looks like something from 20 years ago. Even worse is Dragon Master, never from one moment to the next what your rgb is going to be doing.

Overall Review: Dragon instability is the biggest drawback from me ever buying MSI again.

Solid performer, exceptional Wifi 5/21/2020 8:29:43 PM

Pros: Overclocked a 2x16GB set of inexpensive Timetec ram to 3600 CL 16 easily on this board. The layout is nice and simple, Second M.2 works off the chipset(?) so no unexpected surprises with suddenly losing primary x16 pciex functionality there like some boards. Smokin fast wifi, and rock solid Intel LAN. Rock solid VRM section with a large heatsink. It just works, but you can fiddle with more VRM settings beyond auto should you want to. Higher quality IO shield that has the cushion back without all the little grounding "feelers" that can aggravate a smooth install. Came with latest bios, but handy Bios Flashback function there just in case you need it.

Cons: You do lose two SATA ports to the primary M.2 which happens to most B450 boards, and most all the extra PCIE slots to the second m.2. Not really a con, but this does have MSI's stripped down black and white 'Click Bios". Main difference: You can only save Overclock profiles to a USB stick, -no room internally for that in bios.

Overall Review: This board gives the impression of quality, and the rainbow LEDs are tastefully done.
Some reviewers go on endlessly about how the second 4 pin auxilliary cpu power supply is not really needed, etc. etc.. As a person that has lost a perfectly good motherboard during a bios flash due to a flaky 8-pin, I for one think they should be standard, as they greatly increase the probability that all positive rails are connecting solidly there (take that, Buildzoid!)

Good motherboard and came Ryzen 3000 ready 5/18/2020 4:51:00 PM

Pros: Just a good budget gaming motherboard.
Mine even came with the bios already flashed for Ryzen 3000.
LEDs on the board look nice.
Onboard WiFi and Bluetooth is awesome! No need for a wifi card taking up a PCIe slot.

Cons: 2 USB 2.0 and 3 USB 3.1 is a little short for my preference, could use a few more USBs.
The two antennas in the back get in the way of rest of the back panel ports as they're in the middle the panel. Be better if they were on the bottom or the top.
But these things are pretty minor overall for me.

Overall Review: I wanted a B450 board as a more budget board for a Ryzen 3600X build. I bought this one specifically for the on board WiFi and the bios flashback button, expecting that I would have to flash the bios for Ryzen 3000. It ended up coming with the "Ryzen 3000 Ready" sticker. So that flashback ended up not be needed, Which made building a ton easier! Though, if still purchasing for new Ryzen CPUs be prepared for it not to come flashed, just in case. New bios is fine.

Came quick and as advertised 5/13/2020 9:08:07 PM

Pros: RGB - Oooh pretty colors
AMD 3000 Ready AM4 Socket

Overall Review: The MSI b450 AC Carbon runs great, Has a steel protected PCIe slot for your expensive GPU. I had seen a lot of reviews stating that even though it comes advertised to be AMD 3000 series ready, you still needed to Flash bios to get it to work with any AMD series 3000 CPU, which I ordered at the same time I ordered this board. I had already loaded the update onto a Flash drive prior to delivery to prepare for that, but to my surprise my Ryzen 5 3600 worked right out of the box as advertised. No flash required.
