As graphics cards grow more powerful, the standards that govern how they’re powered evolve. So we’ve upgraded a wide selection of our power supply units to meet the latest ATX 3.1 standard, which ensures stable, efficient power delivery for the GeForce RTX 50 Series and beyond. In this article, we’ll break down what ATX 3.1 brings to the table, how it ties into PCIe 5.1, and why this all matters for your next build.
What is ATX 3.1, and why it matters for your PSU
ATX is the standard that defines a PSU’s form factor, connector layout, and how it delivers power, ensuring safe and stable performance for modern graphics cards. ATX 3.1 is the latest standard, and our current PSU lineup has been upgraded to adhere to it. This reflects our commitment to evolving with industry standards and ensuring future compatibility with next-gen hardware. While an existing ATX 3.0 unit may still suffice for many users, ATX 3.1 delivers the enhanced reliability that power users and hardcore gamers expect when integrating the newest components into their rigs.
The ATX 3.1 standard mandates support for the 12V-2×6 connector, a next-gen cable capable of safely delivering up to 600W of power to high-performance graphics cards like those in the RTX 50 Series. The higher up the GeForce RTX 50 Series power stack you go, the more you’ll want an ATX 3.1 PSU and a 12V-2×6 connection.
ASUS PSUs are ready for the PCIe 5.1 power shift
PCIe is a data transfer standard for graphics cards. Cards built for higher PCIe versions can move more data, enabling faster performance. But powering those data-hungry behemoths takes serious wattage. PSUs are often labeled with PCIe power compatibility to indicate they include the right connectors and electrical support for graphics cards that require next-gen PCIe power delivery, such as the 12V-2×6 connector.
As a result of upgrading all our latest PSUs from ATX 3.0 to ATX 3.1, they now support PCIe 5.1 power delivery via the 12V-2×6 connector, making them fully prepared for the demands of present and future GeForce RTX 50 Series graphics cards. Check out our vast arsenal of power supply units to see the options we offer, all of which are ATX 3.1-compliant and ready to fuel the latest graphics cards and gaming rigs.
