MSI Unveils the World's First ATX 3.1 Ready Motherboards, Based on AMD's X870/X870E Chipset
MSI is thrilled to introduce a groundbreaking feature on its X870(E) series motherboards. This innovative is designed with gamers and professionals in mind, provides the extra power required for AI computing and GPU-intensive applications. The supplemental PCIe Power feature, equipped with an integrated 8-pin PCIe power connector, delivers additional power for GPUs demanding higher wattage, ensuring they can achieve their peak performance. Paired with the ATX 3.1 power standard, which can hold up to a 2.5x power excursion for enhanced reliability and better power delivery, this feature ensures stable, efficient, and sustained performance, even under heavy loads. Whether gaming or tackling complex applications, this supplemental PCIe Power offers unmatched reliability and stability for the most demanding environments.
What is Supplemental PCIe Power?
Think of it as an extra battery pack for your motherboard. The system's 12 V power on the 24pin power connector from the motherboard basically handles all the PCIe interface, fans and RGB extensions. Still, the supplemental PCIe power ensures everything runs smoothly when your PC is pushed to the limit—like when running very intensive graphical games or maximizing all the fan dissipation for extreme performance.
The extra power means you can game harder, work smarter, and push your PC to its limits without worrying about power shortages or system instability. Whether running extremely intensive games or running complex AI applications, the Supplemental PCIe Power ensures your system stays stable and performs at its best. It's like knowing your system will keep up no matter what you throw. MSI's X870(E) series motherboards are ready to support the latest ATX 3.1 and PCIe 5.1 standards, providing the ultimate foundation for future-proof computing. With the addition of the Supplemental PCIe Power, users can confidently run the most demanding games and applications, knowing their system is backed by MSI's advanced power management technology and is prepared for future advancements in computing power requirements.
Breakdown of Key Power Management Features:
Let's take the MAG X870 TOMAHAWK WIFI motherboard as an example of how MSI is pushing the boundaries of performance for demanding users. Imagine stacking it with the powerful AMD Ryzen 9950X processor alongside the cutting-edge GeForce RTX 4090 SUPRIM X 24G GPU. At maximum load, these components demand a lot of power. Usually, the motherboard's 24-pin 12 V power connector can only supply a maximum of 168 W. While this might be enough for basic operations, it falls short when trying to drive everything to its peak—especially with fans, RGB lighting, and a beastly GPU like the 4090 connected.
That's where MSI's 8-pin Supplemental PCIe Power Connector steps in. On the MAG X870 TOMAHAWK WIFI, this additional connector provides up to 252 W of extra power, ensuring everything have enough power to run at their full potential. The 24-pin and 8-pin connectors deliver a combine total of 420 W, giving the entire system plenty of power headroom to operate smoothly, even under the most demanding conditions.
What does this mean for users? The Supplemental PCIe Power ensures MSI X870(E) motherboards have the stable, consistent power needed to handle high-end GPU performance and maximized system cooling simultaneously. Whether pushing a 4090 GPU to its limits or adding a second GPU for AI complex computation tasks, these motherboards are fully equipped to handle the next generation of power-hungry components, delivering performance and stability.
MSI's ATX 3.1 / 3.0 Ready PCIe 5 PSU lineup fully supports the additional 8-pin PCIe power demand, offering stable and efficient power delivery across all connected devices. This includes a robust support of all models across MEG, MPG and MAG, ensuring that power distribution is handled efficiently across the motherboard and connected peripherals.
The MSI X870(E) series motherboards with Supplemental PCIe Power will be available on Sept 26th.

That said, a lot of boards have had this extra 12 V input over the years, but it's never been part of any kind of standard.
German language text based websites claim that PSU (power supply units) with ATX3.1 are worse in specs than ATX3.0. As far as I remember the buffer time from input to output is bigger with the ATX 3.0 specification.
I'm kinda sure I read that the PEG slot, equals the gpu slot, is capable to supply 75Watts. Now I see 66 Watts. I assume that SMD connector for PCIE 5.0 maybe not that capable to provide 75Watts for the PEG slot.
I do expect proper naming of specs. Therefore I prefer 12V-DC. 12 V is not a Power - It's a Voltage. Assuming they meant 14A - that is a current - that's also not a power. (I refer to the wrong labelling on the top left - in colour orange)
I prefer if those connector pins would have been properly named with Voltage & AC or DC & Amps.
I'm kinda sure my old PSU, which I do use sometimes for testing, from 386 and 486 (these are processors) based computers did not had those 8 pin connectors.
It seems there were some extra connector to the processor for a while on mainboards. Without that the mainbaord usually does not boot.

A summary article about USB 4 would be interesting. What is known so far and so on. What is currently available on hardware usually. Mechanically and electrically.
I feel lucky :D
Edit I had to go back to the casemod galleru to see how long ago it actually was….
www.techpowerup.com/gallery/471/details
I'm looking for things with LESS power...not more. My electric bill by RATE has gone up 30% every year for the past 3 years. I'm almost paying double what I paid just 4 years ago. I want things with less power not more so my bill isn't so outrageously terrible every month. I'm like $0.34/kw its unreal...
cdrdv2.intel.com/v1/dl/getContent/336521
However, USB4 2.0 Gen 4 doesn't have a gen anything it seems, it only has symmetric (80 Gbps) or asymmetric modes (120/40 or 40/120).We were hitting the equivalent of 50 cents / kWh here two years ago during winter, this summer it hit minus six cents at one point. That doesn't include the cost to have the electricity transferred to you, which is around 5 cents per kWh and the energy tax and 25% VAT on top of of everything... (yes, we pay tax on top of taxes). This summer has been extremely cheap electricity, with it often hitting minus prices, but the actual saving on the bill was never more than $5.
Now they're going to change the entire electricity system here and implement flow based electricity (whatever that means), so the costs will go up, since they claim this will allow us to export more electricity...
So yeah, more power efficient hardware could be nice.
These MSI boards appear to use a new connector, that's not EPS or GPU connector compatible.
If you flip the image, you end up with square, square, cut, cut and then three cut and one square pin, which means you can't physically fit any current plug into the jack on these boards.
4080 and 4080S uses ~300 watts in games. 7900XT uses ~315 watts, 7900XTX uses ~360 watts.
4070 SUPER beats 7800XT and uses 50 watts less.
Intel CPUs, yeah, if you look at the extreme high-end stuff, i9 (i7-14700K too, since its basicly a i9-13900K) but TSMC 3N for Arrow Lake will probably fix this problem. It's really a non-issue for most people with regular use - Most people don't run Cinebench loops 24/7.
Power usage is also insane in competitive games, which is why 99% of competitive gamers use Nvidia:
Look at 2:30 timestamp if you don't bother to watch it all. It is pure fact that AMD simply uses way more power overall, for worse performance.
7900XTX uses around 325-350% more power than 4080 in CS while losing in performance as well.
LEDs and fans don't use a lot of power. I don't mind USB-C PD connectors needing some extra juice, though.
But nevertheless, I fully agree. I wouldn't wonder, if the new ATX 3.2, and PCI-E 5.2, or whatever new standard is right around the corner.
Not to mention, that these "angular" connector were used for motherboards, along with the usual "straight" ones, even two decades ago. Also, the PSUs use these ubiquitously, even for the cheapest low power products, for like... forever.

To sum it up in my words. I read www.pcgameshardware.de/Mainboard-Hardware-154107/News/Neue-X870-MSI-Details-zusaetzlicher-Stromanschluss-1455527/
There are doubts that this will benefit at all any hardware becasue MSI does not meet the ususual standard for connectors on mainboards. As far as I have understood, there is an extra connector which will give extra amps to certain connectors on the mainboard. A graphic card should not, when it meets the standard, take more Watts from the PEG slot. Therefore an useless feature.
In my point of view. I removed the garbage FAN HUB of my Fractal Design Meshify 2 Case. Many cases come with an additional FAN HUB or it is separately available. Therefore more Watt on the FAN Connectors is not needed. (This also applies to RGB FAN Hub.)
With two 8 or 6 pin CPU Connectors and one 20 or 24 pin ATX connector there should be enough Watt for a mainboard (which includes CPU, RAM and peripherals)
It does not conform with any known connectors.
Could an admin ask a poll to this effect please: How many people who might be interested in an X870 chipset motherboard has any need for this new power stuff.?
