  • What's the regular price?

  • Looks like a pretty good board

    • +3

      Buildzoid, the God of Overclocking, claims that it has terrible VRMs, and that He would not overclock a 3900X on it. I believe He means this in comparison to other B550 boards. I believe it is still good for the price, and He does not explicitly mention that it is bad for the price.

      • +4

        I do believe I saw another reviewer mention that although the VRM is bad, it has a heatsink which is rare at this price point

        • That's what I noticed as well as M2 armour.

        • It's bad compared to $250+ B550 motherboards but still blows any B450 board out of the water (including $260 B450 boards).

          The point to take is that you shouldn't run a 3900X on a $170 motherboard, but go crazy with overclocking a 3600 or 3700X.

          • @Cielescha: Correct or run without overcloacking.

          • @Cielescha: Would it really be better than say msi b450i gaming plus ac? Thought this board had one of best vrms and yet posted board is only okay vrms

            • +1

              @FrozenFred: I would think the B450i has better VRMs but I haven't seen any direct comparisons.

              • @BROKENKEYBOARD: Yeah I think his comments are bit over statements. Not to say it's no good but if going at enthusiast level it's not great. Msi b450i is one of best in its form factor and b550 has some advantages such as pcie4 but other than chipset renewals this AsRock board may just be good not 'excellent'

            • +1

              @FrozenFred: B450I Gaming Plus AC is a bit of an outlier and it is slightly better than this board.

              I haven't really taken it into consideration as it's an ITX board which brings other constraints.

          • @Cielescha: what about b450 tomahawk / mortar

      • Are you able to link to that video or article? I know he has his own youtube channel and is on gamerxnexus, but could not find him talking about it with 3900x

        • +1

          Link with timestamp. He says a 3950X at stock should be fine, but a bit hesitantly. I'd think an overclocked 3900X would draw a bit more current than the 3950X at stock settings, so I would make sure to get some airflow to them if overclocking.

  • Shipping is $9.90 to suburban Melbourne.

    M.2 E-key is something I'm keen on seeing more and more in mainstream boards. The ability to add a Wi-Fi card without using a precious expansion slot and having it integrated into the board is great. The E-key cards themselves are also a lot cheaper than a full PCIe one.

  • Bummer, preordered mine for $195 at mwave from a post a few days ago. Rookie mistake!

    • +1

      Get your crystal ball back in shape rookie

  • Pretty cheap for a b550. is this for just a low end build or can you pair this with a possible 4700/3080?

    • +1

      Should pair with 4700x and 3080 fine, just dont expect any decent overclock on the cpu

      • +1

        Not that you'd expect them to overclock too much higher than stock, I'd imagine

    • +4

      It would have no problem with a 4700 (assuming similar to a 3700X) and the mobo has no impact on the performance of a GPU, just as long as it has working PCI-E slots for it which they all do these days. The limitations with cheaper motherboards are the features you get from it (fewer M.2 slots, fewer sata ports, fewer fan/rgb headers) and how powerful a CPU you can run on it. Of the current generation, anything below a 3900X will run fine on just about anything. Worst case with a 4700 would be overclocking it heavily and temperatures getting high but probably still within the limitations of the board and unlikely you'd ever see any thermal throttling. All this assumes you have a decent enough CPU cooler and case airflow to be doing this sort of thing in the first place.

      • Is there a reason people won't just buy a small fan and point it at the VRM?

        X570 chipset fans are bad, mmkay 'cos you can't replace them easily.

        Why can't people just add their own fan and save hundreds of dollars instead of having to buy the best performing passively cooled VRM?

        It's looks, isn't it.

    • i'd say it's mid tier

  • Well this is finally is easy to get.
    Correct me if I’m wrong but this is the only mATX board in the 550 range. I’m currently running a mortar max Tomahawk with the upgraded BIOS and a 3700X AMD chip.
    I doubt this would be much of a upgrade but as I’ve invested in the mATX case I like I’m sorted limited on options. Anyone else with an mATX case that’s in the situation what are you planning to do?

    • +6

      I think your thinking of X570 where there is only one (consumer) mATX Motherboard by ASROCK. In the B550 range, every major vendor has an mATX variant and most have several.

      • Correct. I bought an MSI B550M Mortar. Very happy with it.

      • Ahhhh yep, I’m totally thinking of the 570. My bad.

  • i know it may not sound fully logical but has anybody tried a Micro-ATX middle class mainboard like this with RTX-2080 in a micro case?
    or that's a dumb idea and better to go with full blown mainboard and case.

    • +3

      mate, i'm using corsair 280x case (mATX case) with RX580 (26cm length) and only have space left for about 3~4 cm to front side fans.
      If your 2080 is longer than this, avoid using mATX case and get normal ATX case instead, you can use mATX Mobo still.

      • Thanks mate , appreciate your heads up

    • +1

      Absolutely nothing wrong with squeezing a high end GPU in a small PC. As long as you have good airflow youll be sweet.

      • Thanks mate , good point for airflow considering the small cubic haul

        • +1

          Mini itx build msi B450i and msi gtx 1080 in a inwin A1 case is sweet ;)

    • +1

      Beyond power delivery for overclocking at the extremes, motherboard tier/price has very little impact on overall performance.

      There is no reason why you couldn't get excellent performance with this motherboard and a RTX 2080, assuming your PSU and cooling is up to the task.

      The more expensive chipsets are more about enabling additional features, additional slots for expansion, extra PCIe lanes etc.

      The vast majority of PC's don't actually require huge volumes of air to cool properly. Smart case design that effectively draws air over hot components and gets rid of it is often easier with a small case, where there are no dead zones where hot air can accumulate. Get a massive case if you like that look, but it's entirely possible to make a very powerful PC extremely compact if you really want.

      • Thanks mate , logically i was thinkin the same but wanted to check with others if the idea doesn't backlash later.

        • It's a few years old now, but this video shows just how much power you can cram into a tiny PC:

          Linus has changed a few parts in this build since, but AFAIK he's still using that case, and similarly powerful hardware, as his living room VR gaming setup 5 years later.

          Having built a couple small PCs, it pays to give it some thought beforehand to make sure the parts you select are suitable and will fit. But there's tons of info out there on what's possible. Micro ATX isn't really all that small anyway…..

          • @klaw81: Awesome , thanks mate. Will check

  • +1

    thanks, OP
    I bought one.

  • OOS

  • Any motherboard recommendations between $250-400? Had a mini from 5 years ago that I bought incorrectly and not having access to all the USB slots (and lack of power) is annoying now

    • which form factor

  • So $20 off.
    Happy with my B450 mortar max for that price

  • Thanks, OP. Purchased one. Now any recommedation for casing?

    • A few options you can look into -

      $60 - Thermaltake H18
      $75 - Antec DP301M
      $90 - Cooler Master NR400
      $110 - Metallic Gear Neo Micro
      $110 - InWin 301

      • The H18 is a pretty good one, but the acrylic side panel is what kills it for me. Airflow is really good.

  • Got a Couriers Please tracking number from the shop but couldnt use it to track my parcel.
