SilverStone is back with us today with its new small form factor SX650-G. This one has a bigger fan and a few more connectors than the previous models, so we are expecting great results from this SFX PSU. This one clocks in at 819 watts per liter and does carry a gold efficiency rating. Flat shorty cables are stock with tiny builds in mind.
