MSI’s line of next-gen MEG power supplies are ATX 3.0 compliant, designed to support 3x “power excursions” for next-gen GPUs

MSI is gearing up to launch its next-generation MEG line of power supplies that will be fully ATX 3.0 compliant. The new power supplies are designed to withstand up to 3x the GPU power excursion and twice the system power excursion.

MSI’s next-gen MEG series of power supplies are fully ATX 3.0 compliant and can handle 3x power excursion loads on next-gen GPUs

We recently detailed the MSI MEG Ai1300P and ME Ai1000P power supplies which are designed to be fully ATX 3.0 compliant. The new standard will be a must for PC builders looking to get next-gen components for their systems. As PCs become faster than ever, power requirements will also increase and it’s not just overall power consumption, but systems need to have a proper power management system that can withstand both power excursions and transient power spikes, it will be more than 2-3 times the rated power.

MSI MEG Ai1300P PCIe5 and Ai1000P PCIe5 power supplies are fully ATX 3.0 and PCIe Gen 5.0:80 PLUS Platinum compatible with an all-new GI engine

MSI is developing its new line of MEG power supplies with this in mind and has stated that the unit will be capable of handling up to 2x the total system power excursion and 3x the GPU power excursion. Now why does this matter because a few years ago when GPUs hit 300W TDPs a 3x power spike would have meant the PSU would have had to handle up to 900W of power at the GPU for a few milliseconds. Those few milliseconds are crucial and if the power supply was not good enough, it would have caused the PC to shut down or restart as an overcurrent protection.

Now, a good high-end 800W to 1000W PSU should have been enough to handle those 300W GPUs, but next-gen chips are said to have 450-600W designs. That means the power supply will have to support up to 1350W of load, a 50% increase in power excursions over the last generation of GPUs.

PCIe Gen 5.0 graphics cards can have “power excursion” up to 1800W, but ATX 3.0 power supplies can keep your PC running smoothly

If power supplies aren’t designed with this in mind, chances are your PC will be completely unstable when running next-gen hardware such as the next line of GPUs from NVIDIA and AMD. We go into more of those details here, but the snippet is that you will definitely need a high-end ATX 3.0 compatible power supply for your next-gen GPU if you don’t want to end up in trouble with your next PC build. You can also check out the Gamers Nexus video on the subject below:

Going back to the MSI MEG line of power supplies, the next feature is the PCIe Gen 5 slot itself. If you were to use an existing PSU with a Gen 5 graphics card, you would need to run an adapter and that comes with its own drawbacks such as cable routing and the use of individual rails. A Gen 5 to Gen 5 connector is more efficient, delivering up to 600W of power, which will be the peak of most next-gen GPUs. The PSU series will also feature a multi/single Rail switch as well as support for the MSI GI (Gaming Intelligence) engine.

Some of the major features provided by the GI Engine through the MSI Center application include:

  • Real-time power status monitor: Thanks to the MSI Center, this power supply allows real-time status monitoring of the percentage of power supplied to the GPU and CPU and the total system power used.
  • Multi/monorail switch: It can switch between single rail and multiple rails according to users’ needs while considering high current output and safety protection.
  • Smart fan mode: Automatically detects electrical load and internal temperature to adjust fan speed. When the load is less than 55% or temperatures are below 70 degrees, the fan will automatically shut down to reduce noise

This truly puts MSI’s line of MEG power supplies among the first to fully support the new PCIe Gen 5 interface. Currently, there’s no word on pricing or availability, but more details are expected to be announced. by the second quarter of 2022. Plus, there could also be an even more powerful MEG PSU on the horizon, stay tuned for news on that soon!
