In the world of high-performance computing, gaming, and professional rendering, multigpu systems are increasingly popular. To support these powerful setups, choosing the right power supply is crucial. The ATX 3.1 standard introduces new features and improvements that make selecting a compatible power supply essential for stability and efficiency.
What is ATX 3.1?
ATX 3.1 is the latest revision of the ATX power supply specification, released to accommodate the growing power demands of modern components. It offers higher wattage support, improved transient response, and better power delivery capabilities. These features are especially important for multigpu systems, which require stable and reliable power sources to perform optimally.
Key Features to Consider
- Wattage Capacity: Ensure the power supply can handle the total power draw of your GPUs, CPU, and other components.
- Power Connectors: Check for sufficient PCIe connectors, especially if using multiple GPUs.
- Efficiency Rating: Look for at least 80 Plus Gold certification for better energy efficiency and lower heat output.
- Build Quality: Opt for models with high-quality components and good reviews for durability and stability.
- Future Proofing: Consider additional features like modular cables and higher wattage for future upgrades.
