Great value
Fantastic value for money ! Great starter motherboard for anyone looking to get into PC's. No mvme support but thats a trade off I was willing to take . Be careful of the size of your GPU due to it being a smaller sized board . Overall impressed with this , overclocking feature too which is rare to see at this price point.

Cheap and Cheerful
Used this for my first ever build thanks to some great reviews on youtube, good compatibility, Bios was updated to ver 3.9 so didn't have to update it before installing my Ryzen 5 3500x. For compatibilty check the ASRock website, great exhaustive list of usable components and which version of Bios needed Bit of a no frills board, minimal connections but should be fine for any standard build. No integrated RGB controls if you want that from your Motherboard as I said it's bare bones offering, just giving you the essentials

Good budget MoBo
Struggled with a few wires when building the PC with this MoBo, but overall pretty good

Great motherboard. Would recommend a fan controller
Great motherboard, easy to find connection points. No fiddly ports however a lack of fan ports.

Does exactly what it's supposed to, easy to install and power and worked out the box.
Used with a Ryzen 3200g and 16gb of corsair ram. Plugged it all in, laser cut a new case for it and hooked up my gpu. Installed windows on a new m.2 drive I bought and have had ZERO problems whatsoever. The manual has enough information for the plugs and it was simple to install. Absolute bargain for the price and I'll happily keep it til it's dead.

Budget board for almost any AMD CPU
works very well with my AMD Ryzen 5 3600. i dont do overclocking so this board is perfect. it comes with a m.2 slot which comes in handy. Came with ryzen 3000 series out of the box which is amazing considering the price I purchased this board for. Comes with 4 SATA III ports but the downsides of this board is that the chassis fan headers are somewhat poorly placed. There is no sort of RGB header, which I can expect. Also just to point out, when installing components like the RAM and CPU, the board makes a slightly disturbing but very subtle cracking sound. On the plus side, if your looking for a budget gaming board or any sort of CPU testing board, this is probably a deal.

B450 for the price of a A320 motherboard !!!!
I purchased this motherboard because it is/was the cheapest B450 motherboard on Amazon at the time. I was wanting it for a slimline pc build. Paired with 16Gb of DDR4 3000 ram and a Ryzen 3200g the board works great. Mine even came with the latest bios supporting the newer 3100 cpu's. You even get an m.2 slot which you don't get on many A320 motherboards at the same price. Overall a good budget motherboard to get you started on a budget. Recommended !!!!!!

Warning! NOT Ryzen 3000 ready!
This mobo arrived with a label on the box declaring Ryzen 3000 ready, I had bought it with a Ryzen 5 3600x. The bios loaded with the mobo was 3.70 but the mobo would not work with the cpu, fortunately I have an old am4 processor I had used to upgrade another mobo when Ryzen first came out, this cpu worked, I then had to roll the bios back to 2.30 at which time the 3600x was recognised.......oh and another thing, I can't get this mobo to work with an m.2 drive on bios 2.70, it did recognise the m.2 on bios 3.70

Scheda madre arrivata con l'ultimo bios ufficiale (10.10), atto a supportare tutta la serie 5000. Utilizzata per sostituire una scheda A320 che ha esalato l'ultimo respiro causa sbalzo di corrente. Economica ma più che sufficiente per tenere in vita, in attesa di un futuro upgrade, un ancora performante Ryzen 7 1800X. Do il punteggio massimo perché non ho riscontrato alcun problema nè nell'installazione nè nell'uso, tutto perfetto. Tengo a precisare una cosa: avevo anche aggiornato il bios alla versione beta 10.42 presente sul sito AsRock. Se però avete una CPU tipo Ryzen prima serie, vi sconsiglio di farlo e vi spiego il motivo. Una volta installato il nuovo bios, il Ryzen 1800X restava fisso alla frequenza di 2.2ghz mentre col bios 10.10, l'ultimo ufficiale, raggiungeva regolarmente la velocità di clock reale, cioé 3,7ghz. Sono riuscito a tornare alla versione precedente (10.10) e adesso tutto è tornato alla normalità. Ho testato la scheda col bios beta 10.42 utilizzando un Ryzen 4500 e questo funzionava da re; ma andava già bene utilizzando il bios ufficiale. Solo per integrazione, la scheda madre è ottima e funziona alla grande.
