SilverStone ST45SF-G 450W SFX Series

The modular SilverStone ST45SF-G power supply is remarkable for its exceedingly quiet idle operation (20 dBA).  Its 80 PLUS Gold level efficiency means it never drops below 87% at 20-80% load. Another advantage is its strict ±3% voltage regulation and ±3% ripple and noise tolerance. Although it is primarily a SFX power supply, thanks to the supplied adapter it can be mounted in any ATX case.

A powerful single +12V rail design provides maximum output current of 37 A, making it suitable for computers with upper mid-range graphics cards. Two PCI Express connectors, which are part of the wiring, match the intended specs. You will appreciate the full modular cable design, which improves air flow and component cooling inside the case. All quality power supply units have obligatory active PFC correction and multiple protection of connected equipment, and the ST45SF-G is no different.
