SilverStone Strider Plus 600 W (ST60F-PS) Power Supply Review
The +5VSB Power Supply
Contents
The +5VSB (a.k.a. standby) power supply is independent of the main power supply, since it is on continuously.
The +5VSB power supply uses a TNY278PN integrated circuit, which incorporates the PWM controller and the switching transistor into a single chip.

The rectification of the +5VSB output is performed by an SBL05L40C Schottky rectifier, which supports up to 5 A (2.5 A per internal diode).
