    After watching the GamersNexus video on their scammy practices, I wouldn’t even get any ASUS products even if we’re free. (edited)

    I wouldn't buy ASUS even at this price as they either wont honour warranty or will try scam you

    Depends on what your definition of cheap is? With the 500 series boards from AMD prices started to rise. The A620 boards in my opinion need to be cheaper as they start at £80 to £90 and are almost the same price as the B650 boards.

    The cheapest AM5 board I would go for is the Asrock B650M-HDV/M.2 for almost £100.

    I have this board but to be quite honest knowing what I learned over the course of setting it up I'd probably have spent the extra for a b550 or something else anyway.

    The first gotcha was that you can't use all the sata ports and an m2 pcie ssd - this is common across all AM4 platforms but worth being aware of if you are thinking about a NAS build

    The next gotcha is that the PCIE 1x slots only run at gen 2 speeds, which is fine for a lot of things, but will speed limit plenty more - this is a b450 limitation.

    The final gotcha, peculiar to this board was that the CPU fan header stopped reading the fan speed for some reason - I ended up having to use the second case fan header and linking that to cpu temperature, disabling the alarm monitoring on the cpu fan - obviously doesn't hint at great build quality, and with only 2 case fan headers this could become a limit quite easily in a lot of modern cases which have lots of fans anyway.

    Fortunately it's been stable in use, but just worth being aware of.
