White Micro ATX motherboard for 9850X3D recommendations

Shashman · Tuesday at 18:04

Afternoon!

Finally splashed out on a 9850X3D and I'm looking for recommendations for white mATX motherboards.

Currently using an Asrock B650M Riptide with a Ryzen 5 7600 but:

A) I want a white mobo to go with the rest of the system
B) I would rather have a board with off the shelf 9000 support
C) I've just splashed out on a powerful CPU so why not combine it with a board which will do it justice

Budget is around £150 but flexible (within reason)
Rest of the components are in my signature, plus 2x M.2s and 1 x SATA SSD.
I wouldn't mind having more ARGB ports as current board only has a couple.

I'm also on the lookout for a white PSU so I'll cheekily tag that onto this post

Cheers!

I've used another variant of this board and its spot on, excellent value for the price:

My basket at OcUK:

1 x Sapphire Pure B850M WiFi (Socket AM5) DDR5 Micro-ATX Motherboard (SKU: MOT-SPR-05691) = £129.95
1 x Lian Li SX Platinum 850W ATX 3.1 PCIe 5.1 80 Plus Platinum Modular Power Supply - White (SKU: POW-LIA-06698) = £109.99
1 x Lian Li SX Platinum 1200W ATX 3.1 PCIe 5.1 80 Plus Platinum Modular Power Supply - White (SKU: POW-LIA-06702) = £139.99

Total: £387.92 (includes delivery: £7.99)

The Lian Li SX series is very good at its current price point if you're after a white PSU, obviously the 1200W is massive overkill for your system but it's well priced and will offer a lot of upgrade potential.

They're A rated on the SPL tier list and review very well:

If you can stretch to £250 the Asus B850 AYW white edition is really good. 1DPC so some of the best RAM oc out there. Also has async (eclk) for core oc too.

Thanks! I had actually noticed that mobo and didn't even know Sapphire did them. Apparently the software lacks fan control. Seems to have what I'd need though.
I've seen people saying that Lian Li PSUs can get noisy?

That's quite a bit more than I'm looking to spend for features that would probably be wasted on me, but appreciate the suggestion.

Some of them might, it'll depend on the model/oem as is the case with any company that sells PSU's.

The SX range has a high quality fan and is by all accounts a very quiet PSU even under high loads.

See here: https://www.kitguru.net/components/power-supplies/zardon/lian-li-sx1200p-platinum-psu-review/5/

I appreciate that they opted to include a high-grade Hong Hua fluid dynamic bearing fan in the unit, these are good fans we have seen in products from other leading brands such as Seasonic and DeepCool. Under most load situations it remains inaudible, or almost inaudible, and only at close to full load will you hear it operating.

As for the motherboard, I've used the B850 M-ATX Nitro and it's spot on, capable of running a 16c processor like the 9950X under load without a problem for prolonged periods. The Pure is pretty much the same board from what I understand, same VRM's and most other specifications at least.

If fan control is an issue you can get some solid third party controllers for £5-10, at £130 it's a steal tbh.

For the motherboard, any opinions/experience with the Gigabyte B850M Aorus Elite WIFI6 ICE?

I think I'm sold on that Lian Li PSU. Love the braided cables too.

I've never used that Gigabyte board, but I've heard it's a solid bit of kit.

If I was buying a PSU for myself right now I'd spring for the Lian Li SX 1200 myself tbh, not that I need that much power but given the small price difference and how long I'm prone to keep the things it's a cracking price.

I think I'll go for the 850w version. Use the price difference towards the motherboard.

Speaking of which, I'm gonna up my budget a bit...

Personally?

Performance wise you gain literally nothing by spending more on the motherboard, and undoubtedly you'll change it out multiple times in the future.

How often are you going to swap a 1200w PSU?

What if you decide you fancy a higher end GPU that needs more juice, as they're wont to do every generation of late?

The 850W would do you just fine, but for £30 I'd take the higher wattage PSU every day of the week if it was that or spending more on zero real world gains on a motherboard. You've already established that you don't need a ton of extras offered by higher end boards, so what's the point? Maybe if you really want to push aesthetics but even then, and especially in an M-ATX build, most of the board is hidden behind other components anyway.

If it's purely a price thing I'd still opt for the cheaper motherboard and 850W PSU.

I get what you're saying, but I've only had my 9070XT a few months so definitely not thinking about upgrading that within the next couple of years tbh.
I've been reading up on the ASUS ROG Strix B850-G this evening and it seems to offer everything I'm after. Decent VRMs, 4 x M.2, all white aesthetic, nice amount and variety of USB ports.

I'd keep a power supply like that for ten years, I wouldn't keep a motherboard for anywhere near that long usually.

Are you thinking about upgrading to a high core count CPU for production/work related tasks down the line? Otherwise you gain zero from better VRM's, you're literally just buying features.

See here: https://www.techpowerup.com/review/sapphire-nitro-b850a-wi-fi-7/5.html

The Nitro and the Pure use the same VRM's and similar heatsinks.

The two large heatsinks cooling the 12+2+1 power phase design did a decent job of handling our Ryzen 9 9950X, with the VRM peak temperature just topping 70°C, and only at the end of our 30 minute full-load stress test.

That's a heavy artificial constant 30 minute load that isn't realistic for most consumer use cases on a 16c32t processor, the CPU you're looking at is a easy to power and cool. An 8c16t CPU under gaming loads will almost never place anywhere near as much stress on your processor or use as much power/generate as much heat. I've ran multiple heavily overclocked systems in the past 20 years on entry level motherboards, you literally only gain features as long as you have sufficient VRM's and bios options -- and as of 2026 overclocking is dead for consumers, you gain more with less faff with undervolts which inherently places less strain on your components.

It's your money at the end of the day, as mentioned even if going with the cheaper PSU I'd still not pony out on a motherboard for zero benefit judging from your initial post.

But then I'm a tight git, as mentioned and I'm sure others such as @tamzzy can attest given my attitude toward overspending on motherboards in the past.

I had a B850-G and it’s an awesome board. Looks really nice and has a brilliant spec. I sold it to go for an atx board and I kind of regret not keeping it.

I'll spend a week deciding which HDMI cable to buy, so trust me I know about being a tight git! I was just thinking that for the first time ever I'd like to splash out on a motherboard. I've never spent more than 100 before, basically always settled for low-mid tier.

I've seen that in general, both the Gigabyte Aorus and Asus Rog Strix boards I previously mentioned perform better and have better features than the Sapphire boards.

Btw regarding that review:

EFI needs some work and is missing some key options
Software lacks fan control
Low-end audio
Low numbers of fan headers and USB ports

These are all big no's for me
