Conclusion
With the SX600-G 600W, SilverStone has a compact SFX power supply in its portfolio with high output power. The manufacturer decided to equip this little unit with a high quality fan. At 20 percent load it's silent, while running the PSU at 50 percent as well as at 100 percent makes it subjectively speaking well audible. What we really dislike are the cheap Su'scon caps. A power supply with such power density should definitely be equipped with only japanese capacitors, especially if you keep in mind the all the wires in this unit make the airflow be far from optimal. High quality capacitors would significantly increase the lifespan of the entire unit, especially if it's going to be driven under high load. It's really a pity there are chinese caps on the secondary side.
If you're planning on building a very small rig, which requires a SFX power supply you can consider this unit. Nevertheless we do not recommend using this unit with high load for a long time, since we do not trust the Su'scon caps in this case.
