Good review Mike and Lady Kath. As you say Mike... Cheap and Cheerful. I always keep a look out for components on sale for a good price. Even a low budget build with parts paired correctly will do a lot more than what most folks give them credit for. Take care all. Cheers

[@mikesunboxing]

thanks rick

[@uglybob7505]

Hope this is the start of a trend of mobos coming back down in price ! Thanks Mike and Kath.......🙂

[@mikesunboxing]

i hope so, mobo pricing is so depressing

[@DylSkiii.]

I’ve got the ASUS PRIME B450M-A II I picked up new along side my ryzen 5600 a couple days ago. Great mobo for the money. Nice amount of usb 3 ports on the back too! Mine was ryzen 5000 ready out the box. Was prepared to use the flash back feature. One thing I’m not so keen on is the ASU’s software for managing rgb. Other than that great board! Runs my ram 4000mhz stable.

@@PapaMav for me, I need one good motherboard with good vrm, at least 3 pcie full lenght PCI-E and lot of m.2 slots. I don't need flashy stuff that increase the cost for nothing. But my 2 other computers has good quality matx motherboards that I bought cheap or as a warehouse deal from Amazon. In all fairness, I always had succes with warehouse deals. The cheaper one I got, an Asus prime a320m-k for 45$ iirc, came without the back plate. For 2$, aliexpress solved the problem.

Cheers Mike I bought this board last week. Confirmed everythings cool for a lil plex serverfor me. Expect for the single fan header. They could've put it on the edge of the board i havent looked yet.😂👊

[@Scott99259]

I have this mobo do you think 5700X 3D will work properly on this board with some aftermarket heatsink on vrm?

[@mikesunboxing]

you really should be looking to pair that CPU with a B550 board, but if you have no choice extra vrm heatsinks are a good idea

[@Paradauskasify]

Got this with ryzen 5600 for 200 Eur, best upgrade ever to use with 6700xt at least 144fps modern games with max graphics on 1080p. No need to invest more, cause next upgrade step is AM5. Mine board came with 4 Ram slots and 6 Sata ports a bit weird. Fan hub is like 8Eur hook up 3-4 fans and no heat throttling.

[@Frawt]

Since you got it for Euros, I'm pretty sure Asus sells the B450M-K II in the UK or something and the B450M-A II in Europe. The M-K II seems to only have 4 SATA ports and 2 RAM slots, while the M-A II looks almost exactly the same, but has 6 SATA ports and 4 RAM slots. Price is about the same, since the M-A II also hovers somewhere around 60-ish euros.

[@l3afl1p]

The perfect video as I am looking in getting this board. You stated that any CPU over 5400 is not recommended. How about a 5500? Would like to know your opinion.

[@mikesunboxing]

that will be fine

[@tnw31]

I'm interested in this board. Could be just what I need. I'd like to ask a couple of questions: 1: Can you please confirm how many case fan headers there are...looks like two? 2: Will there be enough clearance from the CPU to the graphics card slot to fit the Cooler Master 212 Black edition cooler? Thanks

[@mikesunboxing]

you are right on both counts

[@WaleedYassinrududy]

Hello! great video, pretty much the only actually great piece of information on this board, but i have a question, [ all apologies if it's slightly stupid ] , I have this board and there is an m.2 ssd already connected to it, [ WD Blue SN550 NVMe PCIe M.2 250GB ] as well as a 1tb hdd, my aim at the beginning was to replace the hard drive with another 1tb m.2 ssd, but as you said in the video there is only one m.2 slot, so what should i do instead? [ my main reason for replacing the hard drive is speed / loading time in games ] Thank you!

[@mikesunboxing]

get a 1tb ssd that would be the better option for games and can use an available sata port

[@richardsmith9615]

I own this board, and the cpu compatibility was a big selling point to me. I don't use productivity programs, or anything of that nature, however I am a gamer. Do you think this board would be able to support a 5800x3d without thermal throttling the VRM's? I have a noctua nh-u9s chromax, which currently cools my ryzen 5 5600g very well while gaming at 1440p on arc a770. Would really appreciate any response!

[@mikesunboxing]

it will thermal throttle under heavy loads, it really wasn't designed for modern processors and their much higher current draw

it should have an up do date bios unless it is a really old board or old stock. 5700x should be okay with some decent cooling but you are limiting the processors abilities with pcie gen3

1 BIG question: based on the AM4 i can put the ryzen 7 5800X on it but would that be unefficient in some way like do I lose way too many frames because of bottleneck?

you lose the PCIe gen4 support for SSD and GPU and slower IO between the CPU and the chipset, but likely to be less than 5-10% in most cases
