The fully modular Toughpower GT series is designed to deliver 80 PLUS Gold efficiency and is compatible with ATX 3.1 standards. Its native PCIe 12V-2x6 (12+4 pin) modular interface efficiently powers PCIe 12+4 pin graphics cards. Toughpower GT series comes with a PCIe 12V-2x6 connector to offer powerful and stable performance allowing the PSU to natively run next-generation GPUs. The wattage marked on the PCIe 12+4-pin cable connector represents the recommended wattage (Ref. Intel design guideline). The bundled PCIe Gen 5.1 (12+4pin) cable connector of the Toughpower GT 750W can deliver up to 300W for PCIe 12+4pin graphics cards. Featuring an 120mm Hydraulic Bearing Fan to keep friction at really low level. Designed with our Smart Zero Fan to adjust the fan speed and minimizes undesired noise; Powerful single +12V rail can properly deliver the power you need for the best compatibility. The use of LLC and DC to DC circuit design provides very stable operation and enhanced voltage regulation. Offers cable selection for users while powering the system at an advantageous voltage. Low-profile cables make cable management easier, reduces clutter and increases airflow inside the chassis; To protect the hardware, Toughpower GT series is built with industry grade protections: OCP(Over Current Protection), OVP (Over Voltage Protection), UVP(Under Voltage Protection), OPP(Over Power Protection), SCP(Short Circuit Protection), OTP(Over Temperature Protection). Toughpower GT series saves energy through its high energy efficiency up to 90% and is certified to 80 PLUS Gold.
