ATX 3.1 Certified Designed to support next-generation systems, the COUGAR GR series conforms to the ATX 3.1 standard. Featuring a native 12V-2X6 design, it provides power to the next-generation graphics cards through a single 12+4-pin cable. With an 80 PLUS Gold efficiency rating, it offers high-quality stability, durability, and reliability. The COUGAR GR series passes the four strict power excursion tests from PSU ATX 3.1 Guide, in which the spike power consumption must bear up to 200% of the rated power for 100μs. Designed for the Next Generation of GPUs The COUGAR GR series supports the latest PCIe 5.1 specification: its powerful and stable performance meets the needs of next-generation GPUs, delivering perfect power for next-gen graphics cards. Equipped with a modular native PCIe 12V-2X6 connector, the 600mm length provides sufficient slack to reduce the risk of faulty connection during PC installation, without the need for a 6+2 pin adaptor. Notice: Before using the PCIe 12+4pin cable, please visit the GPU manufacturer’s official website to check recommended wattage requirements. Efficiency The GR series features a highly efficient design that surpasses the 80 PLUS Gold standard, to help you save money on your electricity bill. Perfect Fan Speed to Noise Ratio Using COUGAR’s exclusive 120mm rifle bearing fan , the advanced fan blade design enhances airflow smoothness and optimizes silent performance. More Stability, Less Noise Crafted for quiet operation, COUGAR’s exclusive 120mm rifle bearing fan achieves an ideal equilibrium between efficient cooling and minimal noise. Optimized, grooved fan blades are molded with an integrated stabilizing ring, minimizing flex during rotation and reducing turbulence for an optimal and silent cooling experience. Highly durable and consistently reliable 105°C Japanese main capacitor. • The GR’s LLC, DC-DC and Tri-Sense (3.3V, 5V, and 12V) design provides high-quality outputs, with an extremely tight 5% voltage regulation to deliver ultra-stable operation. • Optimally perform in 40ºC working temperature environments. Stylish Design Featuring a sleek embossed black design with ample cable length for easy and aesthetically pleasing PC installation. Fully Modular Cables / Embossed black cables Connect only the cables you need, reducing cable clutter and friction and improving the airflow and the ease of installation of DIY solutions. Features Support PCI Express 5.1 Graphics Cards 12+4 Pin Connector Connect the 12V-2X6 with true 200% power excursion dynamic outputs. Compact PSU Size 140mm length fits most PC cases and makes installation easy. Full Protections SCP, OCP, OVP, UVP, OPP, OTP Compatible with The Lastest PC Technology CCreated for user with current and next-generation multi-core CPU platforms. 80 PLUS Gold Certified Up to 91% efficiency power conversion to cut down your electricity bill. Japanese Main Capacitors Highly durable and consistently reliable 105°C Japanese main capacitors. Silent Spin Groundbreaking grooved blade, rifle bearing fan design lets you experience noiseless gaming. Flawless Operation at 40°C Powerful performance at 40°C ambient temperature. Protection UVP (Under Voltage Protection) If the voltages fall below a certain tolerance value on the single lines, the PSU automatically switches off. SCP (Short-Circuit Protection) In the case of a short-circuit, this feature prevents damage to the core components of the PSU and its System components. OTP (Over Temperature Protection) If the temperature gets too high, the PSU automatically switches off. OCP (Overcurrent Protection) If the current on a single line is higher than indicated, the PSU automatically switches off. OVP (Over Voltage Protection) If the voltages increase above a certain tolerance value on the single lines, the PSU automatically switches off. OPP (Over Power Protection) If the system is oversized and requires more power from the PSU than it can provide, this protection function is activated. Safety Standards
