MSI MAG B550M Mortar Preview

Introduction and Technical Specifications

MSI MAG B550M Mortar Preview


So far in our B550 previews we've looked at two ATX motherboards in the shape of the Gigabyte Aorus Master and Aorus Pro. With the MSI MAG B550M Mortar - that's a lot of M's - we have an mATX motherboard. The smaller form factor has always proved a popular choice amongst those of you who buy the B series of chipsets.

Whereas the ATX size always looks the part, for most of us it's just two or three PCI Express slots that sit and gather dust. Why not reduce the footprint of your PCB, and thus the case you have to buy, and go for a system which still brings you all the joys of a high core 3rd Gen Ryzen CPU and blazing fast PCI Express 4.0 storage and graphics, without putting too big of a hole in your budget? If you're a dedicated gamer then the MSI MAG Mortar could be the very motherboard that gives you everything you want, nothing you don't, and doesn't look cheap in the process. No, we shouldn't judge our motherboard on its looks but given that nearly all cases have windows and most systems have RGB lighting to show off, we'd like the backdrop to our aesthetic efforts to look the part too and the Mortar does.

But we're getting ahead of ourselves, let's look through the important specifications and fan header options before looking at the Mortar in the flesh.

Technical Specifications and Cooling

The main difference we can see at this early stage between the X570 chipset and the B550 is the reduction in the number of PCI Express 4.0 lanes you can play with. Given how few of us own nothing but PCI Express 4.0 M.2s - because to do so you'd need an X570 motherboard so why are you here? - then having one blisteringly quick OS drive and enough bandwidth for your GPU is all that the regular user requires, and the Mortar nails that with PCI Express 4.0 support on the main PCI Express slot and M.2, with the 'hardly slow' PCI Express 3.0 used for the rest. It's a good compromise. You still get plenty of USB ports for your peripherals and 2.5G LAN for rapid data transfer. Think of it like buying the base model of a car, you get all you need and don't pay for anything you won't fully utilise.

mATX motherboards always have reduced cooling options when compared to their ATX counterparts, but the MSI Mortar still gives you enough fan/pump headers to run an AIO and still feed your graphics card with the cool air it requires to push polygons at a prompt pace.

Only reason I can think of for PS/2 to be making a come back is security.
I have worked in business where the IT department have disabled all USB connections to reduce the risks of data theft and malicious software being uploaded. I have heard that this connection is better for competitive gaming too due to the reduced latency and ability to send multiple key strokes simultaneously, I have not noticed a difference but there again im not s1mple lolQuote

somethings gone wrong lol ... 3 of the B550 previews have the same comment sets attributed to them ... unless a couple of long time members have suddenly decided to spam the forums Quote

No. Apparently there was too much cross talk on the traces. It would have been a big issue for 4000. Well, that is what I have been told any way.

Shame, they were stunning boards.Quote
