Frequently Asked Questions
What does semi-modular mean on the CX450M?
Semi-modular means the essential cables (like the 24-pin motherboard and 8-pin CPU power) are permanently attached, while peripheral and PCIe cables are detachable. This lets you connect only the cables you need, reducing clutter inside your case.
Is 450W enough power for a gaming PC?
A 450W supply can handle builds with a mid-range graphics card and a modern processor. However, high-end GPUs with large power requirements will need a higher-wattage PSU.
What does 80+ Bronze certification mean for this PSU?
It means the CX450M operates at a minimum of 82% energy efficiency at typical loads, reducing wasted electricity as heat compared to non-certified power supplies.
Does the CX450M include all necessary mounting hardware and cables?
Yes, the CX450M comes with mounting screws, the fixed motherboard and CPU cables, and detachable cables for SATA, Molex, and PCIe connections.
