Frequently Asked Questions
Do I need 1100W for a single GPU?
Most high-end GPUs do not need 1100W. However, if you have multiple drives or CPUs, this extra power helps. Check your specific system needs first.
Are modular cables safer?
Modular cables are not inherently safer but help management. They reduce clutter which improves airflow. Non-modular units can work just fine.
What is the 12V-2×6 connector?
It is a new standard for modern GPUs. It replaces the older 8-pin connectors. It offers more power capacity safely.
Can I mix PSU brands?
Do not mix cables from different brands. Each PSU has unique pinouts. Mixing can cause permanent damage to hardware.
How to test a PSU?
Use a multimeter to check voltage rails. Or run stress tests with software. Listen for unusual sounds from fans.
