This ASRock motherboard has been exceptional right from the first boot. It has lots of features and has been easy to set up. It accepted the Ryzen 5 3400G CPU with no problems and it is running just fine. Paired it with some G.Skill RAM and a Samsung NVMe M.2 drive (it has 2 NVMe slots and 4 SATA headers) and put them in an MATX TD Gamer case and it's a cool little system. I'll have to wait and see if it holds up in the long run. I've used many ASRock products in the past and with the exception of a few bad caps that I easily replaced (after 2 years use) on a system I built for my brother, the

I'm not a fan of the UEFI BIOS but I'm still enjoying the ASRock brand.I'm hoping for the same ASRock quality as previous boards from them and have no reason to doubt the quality!Installation was uneventful and typical with my only having to dig up a few screws because it has more standoffs than the older one.Been running a FX6120 for a few years now and the old 880G is showing it's age in a place where multiple cores are the thing.Popped a Ryzen 3700X 8 core and the previous power consumption of 95w went down and the thread count is doubled (both are 3.6 GHz)...Running 16 GB of memory and a 5
Con...Shipping time was almost 2 weeks...Pro...budget friendly, solid Mobo that supports Ryzen 2000 series processors all the way to Ryzen 5000 series...Easy overclocking in the Bios...M.2 support...Comes with a Easy to understand manual (for newer PC builders)...I had a power surge that bricked my original mobo that only supported Ryzen 1k and 2k processors (I have a Ryzen 7 2700x overclocked to 4.3ghz)...This Mobo is an updated version of my original mobo and the Bios has been updated for Ryzen 5000 processors, which allows me to upgrade my processor as a nice little Christmas gift for mysel
Got one just to run MS office on 11, paired it with a AMD Ryzen 3 3200G w/ Graphics and 16Gigs of memory in the 2nd and 4th slot , just read the instructions…I had to manually set my memory speed in Bios on both MBs , so be vigilant.Running Crucial 2TB in the M.2 slot, the 2nd one is shared lane so again, read the instructions…My only complaint, knocked a star, for what it is, the primary M.2 slot is right next to one of the PCI slots, this causes a bit of a problem if you plan on using a substantial M.2 cooler and want a card in the slot.I liked this MB so much.. I bought another, this one is
I needed to get a motherboard that worked with my Ryzen 3 3200G CPU that I had lying around in a box, so after getting a used one off eBay that needed a BIOS update to run it (and needed an older processor to be able to do so), I decided to just hit PC Parts Picker and find one that would likely work straight out of the box, which led me to this. My main PC in my studio is using an ASRock board, so I knew I could trust the brand - in fact, the boards are almost identical, but not quite. This mounted perfectly in my microATX rack case, the back panel lining up perfectly with everything in my ca
I just would have waited For the motherboard that I was gonna get three days later then I wouldn't have made a mistake and bought the worst motherboard I've ever bought. This motherboard has been flaky ever since I bought it. It's brand new and I don't know if it needs a BIOS update or what, but how am I supposed to give it a BIOS update if I can't even operate it? This motherboard is terrible. The price is not even worth it. Nowhere near worth it. The USB connection issues with this motherboard was the most annoying. I couldn't use the front panel USB ports and I could barely use the back pan
Solid workhorse. It's been running my TrueNAS setup nonstop. Great IO compatibility, plenty of compatible RAM to put in it (if you can even afford them. Q4 2025 amirite? 😂).Only needed a quick BIOS update to support one of my CPUs. Thankfully it's a really easy process.
Ordered one. Partially defective. Started returns process. It happens.. fine..Ordered another one, it came in a clearly opened box without protective padding. Will be returning this also.Not OK.
