MSI MPG B850M EDGE TI MAX WIFI Review – Sometimes Counterintuitive

Unboxing

MSI has introduced a new line of MAX series refreshes for its AMD 800 series motherboard lineup, and here we have the mid-range MSI MPG B850M EDGE TI MAX WIFI to look at. As the MPG-branded model, it’s got more colors to boot, with this one painted white from the get-go.

Accessories-wise, it’s surprisingly pretty bare bones – you get a SATA cable, an EZ Conn V2 3-in-1 adapter for AIO coolers, a Wi-Fi 7 antenna (separated into the base and the antenna module), plus EZ M.2 Clip II packages alongside a screw tool. Unlike the MAG B850 TOMAHAWK model we reviewed, it lacks a front panel header adapter for some reason. Perhaps MSI thought the target audience of this lineup most likely has a decent case with a combo front panel connector to begin with?

Walkaround

First up, here’s the top-down view of the motherboard layout, and there’s something unusual on this one. Unlike most motherboards, the MPG B850M EDGE TI MAX WIFI doesn’t have a primary M.2 SSD slot with dedicated heatsink; instead, it shares the same giant heatsink with two other M.2 slots, while a fourth slot is located behind the motherboard instead – a design you sometimes see in much smaller mini-ITX form factors, but pretty rare on micro-ATX form factor, which is the size this motherboard adheres to.

MSI has given this motherboard plenty of cooling surfaces to keep the components happy, and notably, the first two M.2 slots (which operates on PCIe 5.0 x4) also gets thermal pads on the base, and that allows heat to transfer to both sides of the SSD to better deal with the more demanding thermal requirements these high-speed drives usually possess.

As for the VRM heatsink, it’s the more conventional split heatsink structure, where the top side usually suffers due to less surface area and thermal mass to work with. The side heatsink is also visually covered by the integrated I/O shield, with embedded RGB lighting powered via a connection that goes through the hole within the heatsink.

In terms of I/O layout, the MPG B850M EDGE TI MAX WIFI features eight USB-A ports (four 10Gbps labeled red and four 5Gbps labeled blue), along with three USB-C ports that are all rated for 10Gbps speeds. Unfortunately, there’s no USB4 connection to be found here, and neither is the 20Gbps USB 3.2 Gen 2×2 in both the rear and front I/O. Other than that, you get a HDMI as the sole display output for the onboard Radeon graphics, while its Ethernet uses a rather speedy 5GbE variant that are faster than some other offerings in this class.

For this demonstration, we’ll be using the MSI MAG A850GLS 850-watt power supply, which comes with dual EPS outputs and a dedicated 12V-2×6 output for high-power GPUs; as for memory, we use the provided Kingston FURY BEAST RGB (DDR5-6000, CL30 variant), which comes with AMD EXPO overclocking profile support.

Teardown

VRM

The MSI MPG B850M EDGE TI MAX WIFI’s VRM is a modest 14+2+1 powerstage setup that, surprisingly, is mostly identical to the MAG B850 TOMAHAWK WIFI’s setup. Both uses 80A MOSFETs for Vcore and SOC stages, though the component differs (the MAG model uses MPS, while this one uses Intersil a.k.a. Renesas); as a matter of fact, the MISC powerstage is the same AOZ5516QI model on both models. For its PWM controller, MSI gave this MPG motherboard a Renesas unit instead.

Storage & Expansion

The storage and expansion setup of this motherboard is quite unconventional, and there’s three things to mention. First, if you have any other add-in cards to use (i.e. capture cards), you’re out of luck with this one: there’s only a single PCIe slot, exclusively operating on PCIe 5.0 x16 standard which only flagship GPUs come remotely close to saturating it.

That’s unusual – existing AMD 800 series motherboards only have 24 PCIe 5.0 lanes to contend with, and what was usually done was having a flexible approach where the primary PCIe slot fall back to x8 mode if PCIe 5.0 x4 SSD slots are in use, but it seems like MSI decides to avoid this complexity with a straightforward x16 (GPU) + x4 (SSD) + x4 (SSD) setup. We do think this rigid approach is the reason why USB4 ended up getting sacrificed, since that connector requires its own PCIe lanes, but there’s no room on this motherboard for it.

For the second part, what this motherboard lose in USB4 is does gain itself a second PCIe 5.0 x4 SSD slot, making it a pretty potent combination for builds focusing on extremely high-speed storage (for virtually all kinds of gaming use, this is beyond overkill). It’s even got the unusual layout where the primary SSD slot is located below the primary PCIe slot, which means the fact of point number three – this model has four SSD slots – meant MSI was forced to position its fourth SSD slot at the back of the motherboard instead.

LAN & Wi-Fi

For network connectivity, there’s the same Realtek RTL8126 5GbE LAN controller found on several MSI motherboards that advertises 5-gigabit capability, while the responsibility of Wi-Fi 7 is taken care by the MediaTek MT7927 chipset that, for some reason, has two other names: MediaTek Filogic 380, and AMD RZ738. Whichever the name it gets referred as, this module supports full 320MHz channel bandwidth that properly taps into Wi-Fi 7’s ultra-high speed.

I/O

Given the lack of high-speed USB controllers, the controller chipsets we found on this motherboard is run-of-the-mill stuff. Besides the AMD B850 chipset, you’ll find a Realtek RTS5429E and a Genesys GL3523 controller responsible for the rear USB ports; meanwhile, at the front we found a Genesys GL9905V that is also capable of USB 3.2 Gen 2×2 links, but was underutilized in this case as it only offers 10Gbps headers at most.

Audio

Audio-wise, it’s the Realtek ALC4080 codec that is pretty common in most motherboards of this class. It’s capable of delivering 32-bit / 384kHz audio, with five capacitors responsible for signal noise filtration. The audio circuit is fairly small, though on its way to the rear audio ports you’ll find the aforementioned Realtek 5GbE LAN controller nearby the circuit, a location that is fairly unusual especially given that it sits pretty far from the LAN port itself.

Other Features

As a mid-range offering, the MSI MPG B850M EDGE TI MAX WIFI does offer several amenities: a proprietary EZ Conn V2 (JAF_2) header for simplifying AIO cooler connections, a 7-segment LED display that is a godsend when troubleshooting is needed, along with EZ PCIe Release that uses button lock to secure the card in place. We do also need to mention a small quirk of this motherboard, and that is the location of its CMOS battery. It’s attached via glue behind the LAN port shroud, which is certainly an odd choice given that there’s a lot of free space next to the B850 chipset.

As for the M.2-related stuffs, there’s the usual tool-less implementations like the Screwless M.2 Shield Frozr, which is particularly large for this motherboard; under it you’ll find two versions of SSD installation mechanisms. Both of the PCIe 5.0 SSD slots uses the first-gen EZ M.2 Clip that relies on plastic clips, whereas the third, PCIe 4.0-based slot employs the newer version that utilizes the push-fit mechanism. We’re not entirely sure why this is the case, but it’s just minor details.

Thermals

Generally, the thermal performance on the MPG B850M EDGE TI MAX WIFI is pretty solid despite the worst conditions it has went through during our testing. In a worst-case open-air passively-cooled situation, the VRM can handle the Ryzen 9 9950X3D at PBO pulling nearly 240 watts at all times, whilst keeping the temperature at 80°C only after an uninterrupted 15-minute stress test. When airflow is introduced, the VRM barely went past 52°C in the same CPU load after the same period of time.

BIOS & Software

For its BIOS, the motherboard operates on the CLICK BIOS X interface that offers high-resolution UI (1920 x 1080), with the revamped design significantly improving the user-friendliness of the interface. There are a few neat features such as Favorites that allows users to build a custom list of settings to be accessed easily in a single page, and a BIOS Log that tracks all of the changes made during that session, which is especially helpful if you’re doing a lot of tuning work.

As for when you booted into Windows, the MSI Center app takes over some of the features like fan controls, which needs to be installed as a ‘module’ (and you can pick which one you want to install at any time). By default, it offers system monitoring and driver update section, along with the usual customer support stuff.

Verdict

At the time of this writing, MSI hasn’t provided us with the pricing of this MPG B850M EDGE TI MAX motherboard, so evaluating value is not really feasible; that being said, the takeaway of this new model is, in our opinion, counterintuitive. The lack of PCIe bifurcation meant that this motherboard lacks some of the key features found in modern-day models, like USB4 support and a secondary PCIe slot for auxiliary cards – and that will eventually limit this motherboard’s potential.

If you can look past that, it’s still a solid motherboard with several bells and whistles to simplify the installation and troubleshooting process, and the VRM is plenty capable of handling even the most powerful Ryzen processors available (note, AMD has since launched the Ryzen 9 9950X3D2 with higher TDP during our review, but we couldn’t get our hands on one of those so it’s hard to say what its power characteristics will be). All in all, it’s a decent motherboard, but improvements can (and shall) be made.
