    Bought one of these a few months ago for an office PC that I was putting together for my mother in law, it's been solid. I would advise anyone building with this board to be careful with the usb3 header, it's plastic shroud grips the cable a little too well and as a result comes off the board very easily. It's not a major issue, but definitely worth bearing in mind while managing cables

    The board supports every AM4 CPU up to 5950X and including 5800X3D.

    Not a great VRM config and no cooling on them.
    They would work, but I'd be concerned about VRM temps and stability.

    Sticking some heatsinks on them and having good airflow over them would help, but really you want a bigger power phase array than this board has, for temps and stability.

    If someone can pay the higher price of those CPU's, I'm sure they can pay an extra £30 for a mobo with a better VRM config anyway (edited)

    Great board by the looks of it at first glance, for under 60 notes...

    Heated OP!

    Great price, could probably push it to a 5700X as long as you have adequate cooling over those VRM's (or even buy some cheap little heatsinks to stick on them.

    Perfect as is for a 5600/G though.

    Complete dribble. And IF a person wanted a higher power draw, sticking heatsinks on inadequate VRMs is going to do diddly-squat.

    Unlike Intel, AMD processors (at least the sane zen4 and below) run at sensible power limits. Any CPU can be abused and overvolted/overclocked to the point that a really expensive MB is needed, but that is not going to be an issue with ordinary AM4 users.

    Great budget motherboard remember to add a fan splitter if requiring more than one fan

    Could I put a Ryzen 3600 with us ? Want a used budget build

    Yep.

    got an i7-2600k sandybridge oc'd at 4.4GHz paired with 1660 6GB, wondering if a 3600 with this MB would be a significant boost or will I have to upgrade the gfx card too?
    pawel.wydra's avatar
    It would definitely help a lot in certain CPU heavy titles like Csgo or even gta V. That being said I would go for 5600, that way it would also last a GPU upgrade in the future

    Things are getting expensive. The pc case I bought last year is double the price now. The best b450 motherboards were cheaper than this.

    Very true
  9. rudey_valentino's avatar
    you could build a very capable machine for possibly less than a 13th gen i3 cpu if you have a few bits lying about and if you dont ...sub £200

    Finally, cheap AM4 boards are coming back.

    OK, its an Asus Prime, meaning world+Dog has been stripped off feature-wise, and its likely very old stock (VGA FFS!) but a great option to build a system from some spares.
