Be quiet! SFX Power 3 450W - PSU, 80 Plus Bronze

The BE QUIET! SFX Power 3 is a 450-watt power supply designed for compact systems with its SFX form factor. It operates with an 80 PLUS Bronze certification, indicating a typical energy efficiency of up to 89.3 percent. This model provides stable and continuous power delivery, suitable for mini-ITX and media PC builds that include a dedicated PCIe graphics card. The unit's active power factor correction helps maintain a consistent output.

For thermal management, the PSU utilizes a single 80mm fan for active cooling. Its non-modular design means all cables are permanently attached, a key consideration for cable routing in small enclosures. The unit includes a comprehensive suite of safety protections, such as over voltage, over power, and short circuit, to safeguard connected components. It is equipped with two 6+2 pin PCIe connectors and three SATA power connectors to support common system configurations.
