Was very happy with this board especially at this price. Pros: Looks good Works good Uefi is ok, easy to OC everything The vrm heatsinks are good, stays acceptably cool Good I/O selection (has USB type C, plenty of USB 3 Decent audio Cons: Hmmmmmmmmm.... Well first, the "polychrome" software is CRAP, but if your savvy you will eventually get it to work. But for me I finally got everything aRGB synched, the fans, the ram, the board etc, then the very next day the boards LEDS and everything synched to it wouldn't turn on. After a semi competent conversation with asrock, it seems the RGB controller itself is no longer working, so I no longer am able to sync anything and the Mobo lights just don't work. CRAP. JUST AFTER WARRANTY. If you use the lower of the two M.2 slots (the SATA one), be aware it shares it's SATA lane with SATA port #3, so you cannot plug an SSD/HDD into SATA port 3 AND have a SATA M.2 installed, it's one or the other, so if you plan to use that m.2 port you effectively lose one of the few SATA ports. Not sure if that's on all boards or what but it's kind of lame. No wifi option, I bought a good adapter and Intel WiFi/Bluetooth m.2 card, works great ($30) This is still the best looking board at this price, however the asrock quality should be a topic of consideration if you really care about the aRGB stuff. I will have a really hard time picking asrock in the future. EDIT: SO after a year, i finally decide to try asrocks ploychrome asrrgbled cant decide on name software, and guess what. Firmware updates automatically after starting up the program, and guess what happened? Go ahead, after reading my review, guess. MOBO LIGHTS! Are back on. Check out my review on the cpu cooler ive used the entire time, its the UpHere 5v argb one, you'll see my pictures there. I highly recommend that cooler and matching case fans. I give this board a bump from 3-5 stars for full functionality. It's asrocks software that should get 1 star.

I recently lost a motherboard due to a power surge. I also started noticing some issues with my gaming video card, so, when I replaced the motherboard, I did not install the gaming card. The board works great and starts quite quickly. And, to my surprise, I'm still able to play a lot of my games at decent quality with the motherboard alone. I am older, as are my games, but as an example, I'm able to play Borderlands 2 and Minecraft with the graphics turned up, and they look and play great. This is my first ASRock mb, and I highly recommend it. I haven't played with the lighting yet, but it looks great out of the box.

Purchased this for a build with one of my students. I bought two other motherboards (both MSI) and they BOTH were DoA. I've always used ASUS (until the MSI garbage) but happened to scroll across this ASRock B450M Steel Series. After reviewing the motherboard on the ASRock website (which is an awesome website for reviewing motherboards...their diagrams and pictures are perfect!) I decided that this would be a good motherboard for the build. Upon receiving the motherboard everything was intact and, pulling it out of the box, the attention to detail was terrific! The student installed it, along with all the components, turned it on and...SUCCESS!!! The RGB lighting is perfect and not too dominant. Along with his RGB case and fans everything looked amazing! We went with a Ryzen 5 5500 CPU and I do believe we have a winner! Never used ASRock before but I'm jealous of my student's PC. I love my all-white RGB build but I don't have an RGB mobo...and the ASrock is extremely aesthetically pleasing! As for the motherboard's performance, time will tell. But given how bad QC at MSI is I will definitely be looking at the ASRock brand for future builds/upgrades! Great product, pleasing to the eyes, great price and will hugely recommend!!!

Edit : bios options don't stick properly, will likely need an update. Ui doesn't display properly on 4k screen. Also due to the power phase design im assuming the stepping for ram voltage is pretty pathetic .05v jumps. I usually opt for higher end with more phases so I probably should have expected that on this one. Still a downside no doubt. Nice matx board with everything you need. Bought it to stick a 2600x in, works great without issue. Supports 3200mhz ballistix sport, haven't tried oc'ing but works at xmp speed. Had an issue with the polychrome argb utility, but after uninstalling then reinstalling through the app center it worked fine. Plenty of fan headers along with 2rgb and an arbg header. Huge plus on a matx board. Many of the others I looked at only had 2 fan headers. Two m.2 drives are a huge pro as I put this in a case with limited space. NOTE - the bottom m.2 is sata only and the upper one is nve only (almost sent the board back before recognizing this). I won't be using any other significant features with this board so I won't try to speak to them. Other than that it looks great, works for my needs. I actually bought this off the warehouse as they were out of New ones at the time. Was a bit worried, but didn't find anything wrong with it. I will say the ui is a bit crappy, but other than that I find it pretty difficult to find anything negative to say. I'm happy with it, if you're looking for a decent b450 this one fits the bill.
