Know before you buy
The 80 PLUS Platinum rating indicates that this power supply is highly efficient, converting up to 92% of power from your wall outlet into usable energy for your PC. This high efficiency reduces wasted energy as heat, which can lead to lower electricity costs over time compared to less efficient units.
Yes, the Toughpower PF1 features a compact 140mm depth, which is shorter than many standard ATX power supplies. This smaller footprint provides extra clearance for cable management, making it an excellent choice for builds where space is at a premium.
The Smart Zero Fan mode keeps the 120mm fan completely stationary when the power supply is under low loads, such as when you are browsing the web or doing light office work. The fan only begins to spin once the load reaches a certain threshold, ensuring your system remains silent during quiet tasks.
Yes, it is fully modular, meaning every cable can be detached from the power supply unit. This allows you to use only the cables your specific build requires, which significantly reduces clutter and improves airflow inside your case.
The unit is built with 100% high-quality Japanese 105°C capacitors, which are widely considered the gold standard for durability and stability. These components are designed to handle high temperatures and provide consistent power delivery over the unit's 120,000-hour MTBF lifespan.
With 850W of power and four dedicated PCIe connectors, this unit is well-equipped to handle most modern high-end graphics cards. Its strict voltage regulation (less than ±2%) ensures that your GPU receives stable power even under heavy gaming loads.
