Thinking of downsizing my rig and going from a very large ATX case to something more modest like a Micro-ATX.

Of course ill need to change my motherboard, Will there be much difference going from X870E to a B850M chipset?

Rig in sig,Cheers!
 
According to "standard specs", B850 drops you to PCIe 4 on the main PCIEe slot and the nvme slot, drops wifi 7 to wifi 6 and drops USB4 to 3.2.
However there are B850 boards out there that have some/all of the X870 features enabled...somehow. If any of them matter to you then doen't write off B850, just just the specific board specs.

You sure that's not a B650 standard?
Pretty much all the MATX B850 board's that I've looked at, have had a PCI-E 5.0 main slot along with it's NVME, and I'm only looking at the £150-200 range, so nothing over the top?

Officially PCIe 5.0, Wifi 7 and USB4 are all "optional" on B850 boards as opposed to Standard/Mandatory on X870 boards. I just think we're far enough down the line that all B850 boards that actually want to sell will have a PCIe 5.0 16x slot.
PCIe 5.0 nVME, Wifi 7 and USB 4 however are harder to find.

Yeah X series board are always a cash cow rip off - every generation they deliberately hold back features that clearly currently exist, thus should come standard. All so they can con you into buying either an expensive X series board, or have you wait ages till half way through the lifespan to get it on a B series board.

Yep, same story when I bought my X670E board. I wanted USB 3.2x2Gen2.2x2... but none of the B series boards had it. Now I look back and they ALL got it eventually.

Yeah, locking stuff behind a paywall, despite the technology clearly being available/possible, is hardly what I'd describe as 'next level/revolutionary'. To be impressive, it should be standardised. It reminds me of how Japanese cars give you all the optional extras as standard, (or at least used to until recently) and they cost half the price, yet a German car twice the price has sod all and everything is optional, at a price!
I really do hate corporate greed.
 
Interesting thanks for the replies guys, Honestly the only thing that I would like is to retain PCI-E 5 Main slot, Not because i need it right now but for next generation of GPUs probably.

The rest I'm not fussed about, I only use Pci-e 4 Nvme that's plenty, Don't use Wi-Fi on my Desktop etc

The only concern i have is if they cut down on Mosfets and Chokes on B850M been a smaller board, Not that i overclock and never will, But of course wouldn't want my lovely 9800X3D been starved of the POWA it needs!
 
I'd highly doubt the latter will be an issue, as I say there's many B850 MATX's for £150-200 with Wifi6/7, PCI-E 5.0 slot and NVME, so you'll be fine :D

Some of the cheaper ones (like ~£100 region) are not great, though still not likely to throttle the 9800X3d when gaming.

The midrange boards, like Sapphire's Nitro should have no issue, they're roughly entry full size B850. Then on the higher-end, like TUF-Plus, that's a VRM equivalent to the same boards and could handle 16 cores if necessary.
 
You currently have the x870E Pro Art, so does this imply even the most expensive mATX board is in you budget, or are aiming for better value now?!

Because even the MSI B850M Mortar with 2 X NVMe PCIe 5.0 slots is "only" around £200. Compared to the B850 Tomahawk you mostly lose on the CPU VRMs being 60A Vs 80A.

The most exponsive mATX seems to be Asus Strix and all it seems to bring is x 4 NVMe slots - although only one PCIe 5.0. oh and the 80A rating on the VRMs.

That Lian Li 207 at over 45l is pretty big - at least if they mainly market it mATX.

However the Corsair Frame 5000D RS Airflow is huge at over 75l, so that leaves plenty of scope for downsizing with the same ATX hardware the OP already has - I know very boring!

While there are some <35l ATX cases (I filtered for ATX with at least 340mm GPU), there isn't that much choice.
Maybe the Cooler Master Qube 500?

Mesh-y look like that Corsair. Has the PSU moved to front with the mains cable routed behind the motherboard which also means it decent space behind the motherboard - should make cable routing easier.
Or another Cooler Master, the much plainer MB600L?

Both under 40l so nearly half the volume of the huge Corsair?

I actully did come across one under 30l ATX case, the Nox Lite010 (however filtering for 320mm and under for the GPU would bring back a lot more):

Does seem a bit lacking in features - and I couldn't find any vendors in the UK.
