SilverStone Strider S Gold ST55F-G 550W

The SilverStone Strider S Gold ST55F-G 550W modular power supply operates quietly at 18dBA when idle. It is made from top-of-the-range components and can be used 24/7 without the need to switch it off, even in ambient temperatures of up to 40°C. The SilverStone Strider comes with an 80PLUS Gold certification, which guarantees that it has more than 87% energy efficiency at 20 - 80% of rated load. Another advantage is strict voltage regulation in the range + -3% and simultaneous minimisation of the ripple effect and noise with a tolerance of +- 3%. Its exquisite quality is also clear in the fact that its peak power is actually 50W higher than listed on the label.
 
The SilverStone Strider S Gold offers a maximum current output of 45.9A on a 12V rail, making it ideal for high-end graphics cards or a pair of mid-range cards. You will also appreciate the complete detachability of all cables, boosting the airflow and component cooling inside the case. Similarly, the power supply's compact design with a depth of just 140mm will be appreciated by all users. A mandatory component of all of the higher-quality power supplies is active PFC correction and the protection of multiple connected devices - and the SilverStone Strider S Gold definitely does not lag behind in this regard.
