MSI has launched a new series of motherboards, the AMD X870 and X870E, designed to meet the growing power needs of modern gaming and professional systems. These motherboards are the first to support the ATX 3.1 power standard, offering improved power delivery and stability for high-performance tasks. They come with a new feature called Supplemental PCIe Power, which provides extra power for demanding GPUs and other heavy-duty applications.
What is Supplemental PCIe Power?
The Supplemental PCIe Power is an extra 8-pin connector on the motherboard that works with the regular 24-pin connector to deliver more power. This extra power is especially helpful for users with high-performance GPUs like NVIDIA’s GeForce RTX 4090 or AMD’s Radeon RX 7900 XTX, which require more wattage to run at full capacity. With this additional power, users can enjoy more stable performance when running intense applications like high-end games or AI computing tasks.
This feature ensures that the system remains stable even under heavy load, reducing the risk of crashes or slowdowns caused by power shortages.
ATX 3.1 and PCIe 5.1 Ready
The ATX 3.1 standard allows for more reliable power delivery, handling up to 2.5 times the power spikes compared to previous versions. This makes sure that the system gets a steady power supply, even during demanding tasks like gaming, 3D rendering, or running AI programs. Combined with support for PCIe 5.1, these motherboards are ready for the next generation of GPUs and devices, making them a solid choice for future upgrades.
MAG X870 TOMAHAWK WIFI: A Performance Example
One of the top models in this new series is the MAG X870 TOMAHAWK WIFI motherboard. If paired with an AMD Ryzen 9950X processor and an NVIDIA GeForce RTX 4090 GPU, the system would require more power than a regular motherboard can provide. A standard 24-pin connector can only supply about 168 W, which may not be enough for high-performance components.
With the Supplemental PCIe Power feature, the motherboard can provide an additional 252 W, bringing the total available power to 420 W. This ensures that the CPU, GPU, cooling systems, and any additional devices receive enough power to run smoothly, even during heavy workloads.
Power and Stability for Heavy-Duty Tasks
The AMD X870 (E) series motherboards are designed to deliver reliable power and system stability. Whether users are gaming or working with complex programs, the Supplemental PCIe Power ensures that the system will run efficiently without power drops or interruptions.
This extra power capacity is especially useful for users who need to overclock their GPUs or run multiple high-powered devices simultaneously. It allows the system to handle these tasks with greater stability, reducing the risk of crashes or performance issues.
MSI’s Power Supply Support
To ensure users get the most out of their new motherboards, MSI has also updated their PSU lineup to fully support the 8-pin Supplemental PCIe Power feature. Models from the MEG, MPG, and MAG series offer reliable and efficient power distribution, ensuring that all connected devices and components receive the necessary power for optimal performance.
Availability
MSI’s AMD X870 (E) series motherboards will be available on September 26th. These motherboards are designed to support the latest power standards and provide the extra power needed for the most demanding applications, making them a solid choice for gamers, professionals, and anyone looking to build a powerful, reliable system for the future.
