Designed with a native PCIe 12+4pin modular connector, the Toughpower SFX series is built for next-gen PCIe Gen 5.0 graphic cards, and is fully compatible with Intel ATX 3.0 specifications. The fully modular Toughpower SFX series comes in 1000W, 850W, and 750W, and is built to deliver 80 PLUS Gold efficiency. The compact size of Toughpower SFX Gold series perfectly fits in any ATX or ITX case.
No Matter the Case Size, We've Got You Covered
The Toughpower SFX 850W Gold comes with an SFX to ATX adapter bracket as an accessory which gives users more options when choosing the ideal case for the build.
Fully Compatible with Intel ATX 3.0 Specifications
Toughpower SFX series is fully compatible with Intel ATX 3.0 Specifications which supports up to 200% power excursion, reaches 70% low load efficiency and complies with required power supply timing standards.
PCIe Gen 5.0 Ready
Toughpower SFX series comes with a 16pin connector to offer powerful and stable performance allowing the PSU to natively run next-generation GPUs.
The wattage marked on the 12VHPWR’s connector is the recommended wattage. (Ref. Intel design guideline) The native 16 PIN (12VHPWR) PCIe connector of the SFX 850W can deliver up to 450W for PCIe 5.0 graphics cards.
Made to Comply with the Latest Graphics Cards
As the power consumption of graphics cards has increased, so has their demand for power. The SFX series is designed to support NVIDIA and AMD graphics cards, ready to supply the graphics card according to their different ways of connections.
Be Smart, Stay Quiet
The fans audible noise is under 29.8 dB at 100% operation, this creates the perfect balance between silence and superior cooling. Furthermore, with the Smart Zero Fan, the fan will not spin until the load exceeds 30% of the power supply, minimizing the fan noise.
＜30mV Low Ripple Noise Design
Top-end build quality with low ripple noise. All ripples are lower than 30mV on +12V, +5V or +3.3V from 0% to 100% load to ensure a stable operation and keep your performance-critical components to function reliably for longer.
Extremely Strict Voltage Regulation ＜±2%
The voltage regulation, more strict than Intel’s standard +5%,-7% for major rails and ±10% for -12V, is set to no more than ±2% for major rails, providing steady clean power through exceptional voltage stability.
17ms and up Hold Up Time
During a power interruption, your computer might shut down or reboot. We make sure the SFX series will deliver at least 17ms at 100% workload, without system reboot or resetting.
Fully Modular Low-Profile Flat Cables
Offers cable selection for users while powering the system at an advantageous voltage. Low-profile flat black cables make cable management easier, reduces clutter and increases airflow inside the chassis.
More Stable than Ever
100% high quality Japanese 105°C/221°F electrolytic capacitors provides great durability as well as offering the highest stability, while remaining reliable.
High Amperage Single +12V Rail & High-Class Technologies
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.
92mm Fluid Dynamic Bearing
Featuring a 92mm fluid dynamic bearing fan to guarantee superior cooling performance.
80 PLUS Gold Certified and Intel C6/C7 States Ready
Toughpower SFX series saves energy through its high energy efficiency up to 90% and is certified to 80 PLUS® Gold. The series has been optimized to work with all generations of Intel’s processors to achieve maximum energy saving.
