Thermaltake has announced the launch of its latest addition to its PSU line-up, the Toughpower SFX series, a new power supply range which is designed to meet ATX 3.0 standards and is PCIe Gen 5.0 ready. Designed to run with the RTX 40-series series graphics cards and the latest Intel CPUs, the Toughpower series comes with an SFX-sized form factor and fits in the mainstream ATX and ITX cases, which is essential for users looking to put together a smaller-footprint build.

Thermaltake Toughpower SFX Power Supplies

The Toughpower SFX series is fully modular and compatible with Intel’s ATX 3.0 specifications, which allows users to run the latest RTX 40-series series graphics cards natively via the new 12+4 pin PCIe Gen 5 connector. In addition, it can pump up to 600 W of power over a single 12+4 cable, providing you with reliable and uninterrupted power. It is also worth noting that the Toughpower SFX series’s components have been massively upgraded this time to meet ATX 3.0 standards, guaranteeing up to 70% efficiency at 2% load and complying with power supply timing standards, ensuring a silky smooth experience even at full load. In terms of its build quality, packed with 100% high-quality 105 °C Japanese capacitors, the SFX series is made even more durable and stable than ever before.

On top of that, the built-in Smart Zero Fan (750 W&850 W: 92 mm; 1000 W: 120 mm) makes absolutely no noise at all when running under 30% load. The Toughpower SFX series features low ripple noise, strict voltage regulation, and extended hold-up time. Firstly, from 0% to 100% load, ripple noise produced from 12 V, 5 V, and 3.3 V are consistently under 30 mV, bringing extensive lifespan and overall superior protection for your system. Secondly, the Toughpower SFX series promises ±2% voltage regulation compared with Intel’s standard +5%, -7%, and ±10% for -12 V. Last but not least, the 17 ms hold-up time will prevent your system from rebooting and makes sure the system still runs perfectly even with a brief interruption.

If you’re in the market for an SFX-sized power supply that can support the RTX 40-series series, the Thermaltake Toughpower SFX should be on the top of your list, considering its top-tier materials, well-thought-out features, and comprehensive compatibility with all the RTX 40-series series graphics cards, which enables you to build something extremely powerful while looking small and taking up less space.


Made for the Next-gen Graphics Cards
Designed with a native PCIe 12+4 pin modular connector, the Themaltake 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 1000 W, 850 W, and 750 W, and is built to deliver 80 PLUS Gold efficiency. The compact size of the Toughpower SFX Gold series perfectly fits in any ATX or ITX case.

No Matter the Case Size, We’ve Got You Covered
The Thermaltake Toughpower SFX Gold series 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
The Thermaltake 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 16-pin connector to offer powerful and stable performance allowing the PSU to natively run next-generation GPUs.

Made to Comply with the Latest Graphics Cards
As the power consumption of graphics cards has increased, so has their demand for power. The Thermaltake SFX series is designed to support NVIDIA and AMD graphics cards, ready to supply the graphics card according to their different ways of connecting.

Be Smart, Stay Quiet
The fan’s audible noise is near silent 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.

<30 mV Low Ripple Noise Design
Top-end build quality with low ripple noise. All ripples are lower than 30 mV 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
The voltage regulation, more strict than Intel’s standard +5%,-7% for major rails and ±10% for -12 V, is set to no more than ±2% for major rails, providing steady clean power through exceptional voltage stability.

17 ms 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 17 ms at 100% workload, without system reboot or resetting.

Fully Modular Low-Profile Flat Cable
Offers cable selection for users while powering the system at an advantageous voltage. Low-profile flat black cables make cable management easier, reduce clutter and increase airflow inside the chassis.

More Stable than Ever
100% high-quality Japanese 105°C/221°F capacitors provide great durability as well as offer the highest stability while remaining reliable.

High Amperage Single +12 V Rail & High-Class Technologies
A 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.

92 mm/ 120 mm Fluid Dynamic Bearing Fan
Featuring a 92 mm fluid dynamic bearing fan (120 mm in 1000 W) 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 of 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.
