With advancing technology and increasing power demands, ATX 2.0 power supplies have been replaced by ATX 3.0 units. Nowadays, when you look for a power supply, you’ll often come across ATX 3.0 and ATX 3.1 models. Naturally, you may be wondering what ATX 3.0 and ATX 3.1 power supplies are. In this article, we’ll introduce these next-generation power supplies.
In short, just like USB, PCIe, and WiFi, power supplies also have their own standards. ATX 3.1 currently represents the most up-to-date PSU standard. The shortcomings of ATX 3.0 were addressed with ATX 3.1, and the standard will continue to improve in the future.
Innovations Brought by ATX 3.0 Power Supplies
The most important innovation introduced with ATX 3.0 is the new-generation 12VHPWR (12 Volt High Power) connector for graphics cards. Thanks to this connector, a single cable can deliver up to 600W of power to a GPU. However, not every 12VHPWR connector supports 600W, so it’s important to check before buying a PSU.
ATX 3.0 power supplies must be able to handle up to 175,200 power on/off cycles over their lifetime without failure, which highlights their durability. Since higher-quality components are used, they also tend to be more expensive.
Another major upgrade is the ability to handle sudden GPU power spikes. The small 4-pin section on the 12VHPWR connector enables communication between the GPU and PSU, preventing sudden shutdowns caused by power shortages.
ATX 3.0 power supplies are also required to be more efficient during low-power usage and sleep modes, leading to better overall efficiency.
They must also provide faster startup response, meaning your PC components should receive power more quickly when you press the power button.
Additionally, the ATX 3.0 standard introduces future improvements such as new efficiency certifications and noise level testing under load. This means efficiency labels will also indicate how loud a PSU is under operation.
In summary, ATX 3.0 power supplies brought us improved stability, efficiency, and a brand-new connector standard.
Innovations Brought by ATX 3.1 Power Supplies
- Upgraded GPU Power Connector: The 12VHPWR connector introduced with ATX 3.0 has been updated and improved in ATX 3.1, now renamed 12V-2×6.
- Hardware Improvements: ATX 3.1 PSUs feature better circuit designs for handling power fluctuations.
- Updated Compatibility Standards: Optimized for next-generation hardware. With PCIe 5.1 support, ATX 3.1 PSUs can communicate with the latest GPUs and deliver more stable power.
- Improved Energy Efficiency: Offers better power utilization, helping systems consume less electricity.
ATX 3.1 power supplies are designed to handle sudden power demands even more effectively, making them especially suitable for CPU-intensive games and professional workloads where stability under power fluctuations is critical.
Conclusion
In short, for next-generation hardware, we recommend using a next-generation power supply. If you want stable performance, you may need to slightly increase your budget. ATX 3.1 power supplies introduce innovative solutions, but these upgrades require higher-quality components, which naturally increases their price.
