Industrial-grade Temperature Resilience

The GX Gold 1050/1250 ATX3.0 has improved to operate safely at up to 50 degrees Celsius ambient for high-end computer, overclocking and other high intensity applications. Such a high threshold greatly enhances the performance of your PSU and your system.

Fully Modular Cabling

The fully modular version of the GX Gold 1050/1250 ATX3.0 comes with a set of flat black cables that can be customized to each user's individual needs. It's designed for easy cable management that each system only needs to include the cables required. This unused space within the chassis allows for reduced clutter, better airflow and aesthetic, thereby improving your system's overall cooling.
