Cooler Master took the initiative and continuously developing our first ATX 3.1 Power Supply lineup. Compliant with ATX 3.1 standard and 12V-2x6 connectors, the GX Gold 1050/1250 ATX 3.1 can fully support the peak power drawn by the 40 series RTX graphic cards and whole system.
Efficiency has always been one of the most important factors for users when choosing their power supply unit. While there are a range of efficiency options, 80 PLUS Gold has been the ideal choice for the last several years and continues to be seen as the standard for much of the world. The GX Gold 1050/1250 ATX 3.1 features 80 PLUS Gold certification, guaranteeing 90% efficiency at typical load.
The GX Gold 1050/1250 ATX 3.1 has been optimized with an 140mm fan along with an advanced fluid-dynamic bearing (FDB) delivers quiet and effective cooling with a long lifespan. With Smart Thermal Control System (STCM), the fan will not spin until at 40% of rated output power to reduce noise.
*The fan curve is tested under ambient temperature of 25 degrees Celsius and core temperature is related to load.
The GX Gold 1050/1250 ATX 3.1 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.
The fully modular version of the GX Gold 1050/1250 ATX 3.1 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.
