    Good budget motherboard, has the things you expect from a budget Micro ATX, and the addition of Asus Aura Sync makes it a great buy if you have a Strix GPU. This was the main reason I bought this board.

    Haven't had any thermal issues with it yet.

    It's Asus, its Great. My only concerns are that there are no usb 2.0 ports in the in the back and that there are no vrm heatsinks so i cannot push overclocking. But a simple fix is to buy aftermarket onces i guess..

    I decided to use the Asus PRIME B450M-A Micro ATX motherboard for this build. While small, it packs in a bunch of features. Based on the 450 chipset, it also has support for overclocking; taking advantage of the fact that Ryzen CPUs are unlocked. At the time of building, it was £59.99 on Amazon new. This can be bought here.

    I like it, it's premium when it's your first build, for a mATX and my GPU, I don't have any more PCIe slots.

    It's comparatively a lot cheaper.

    Overall a decent mobo considering the price, I still have to see if there's a way for me to fit my networking card in beside my GPU but fair warning it's a bit of a tight squeeze, I guess that's what u expect with Micro ATX. Bios was clean and easy, install was super quick

    I am a fan of ASUS again thanks to my recent experiences with their motherboards, the A320-M dying on me notwithstanding. Excellent UEFI and the AI Tweaker overclocking is pure genius. The only knock against this micro-ATX motherboard is that ASUS inexplicably placed the PCI-e slot to take up the 2nd and 3rd case slots instead of the expected first and second which really didn't make much sense to me especially since there is no standard PCI slot above it. This required me to remove the case's HDD cage in order to accomodate the graphics card. No biggie, but a rather unexpected minor nuisance.

    I don't recommend it at all. It gets the job done, but it's only got 2x 4 pin headers for fans which made it a pain, the money I spent on fan splitters could have been spent on a better board
