Compact SFX Form Factor with Quiet 80mm Fan
The SFX form factor is significantly smaller than the standard ATX form factor, making it the perfect choice for mini-ITX and other small form factor builds. Our 300W SFX power supply adheres to the SFX specification, ensuring compatibility with a wide range of compact cases. Its dimensions are 125 mm (W) x 63.5 mm (H) x 100 mm (D), allowing it to fit comfortably in space-constrained systems. Despite its compact size, this power supply doesn’t compromise on performance or features. For example, the Silverstone 300 is a popular choice for compact systems such as home theater PCs (HTPCs) and desktop replacements. You can also browse our ATX Power Supply if you need a larger form factor.
To keep the power supply cool and quiet, we’ve equipped it with an 80mm fan. This 80mm fan is designed to provide optimal airflow while minimizing noise. The fan speed is thermally controlled, meaning it adjusts automatically based on the power supply’s internal temperature. At low loads, the fan operates at a lower RPM, resulting in near-silent operation. As the load increases, the fan speed ramps up to dissipate heat effectively. This quiet operation makes our 300W SFX power supply an excellent choice for environments where noise is a concern, such as home theaters or offices. The Silverstone Technology 300W SFX features a silent running 80mm fan with a minimum of 18 dBA, making it very quiet under low to moderate loads. It also comes with protection features such as Over Power Protection, Voltage Protection, and Short Circuit Protection. If you need a larger fan, you can check our 80 plus gold fully modular ATX 3.0 power supply ensures gold efficiency in power delivery. for reference.
