Silverstone SX650-G 650W Modular ActivePFC SFX 80plus Gold PSU

After pioneering full featured, high performance SFX power supplies in 2012, SilverStone has continued refining the segment it has created. The SX500-G and SX650-G are yet another evolutionary step toward perfecting this small form factor power supply category. They are more powerful without growing in size to achieve class-leading power density levels of 633W per liter for the SX500-G and 818W per liter for the SX650-G. This increase in power density was achieved through more advanced engineering and component selection so rather than added noise as is the norm for upping wattage output in power supplies, the SX500-G and SX650-G are quieter than their less powerful predecessors. Their noise signature was further lowered thanks to the use of 92mm fans versus 80mm on previous models. For connectivity, the SX500-G and SX650-G are equipped with more connectors so they can be used in wider variety of system configurations. SilverStone’s famed short, flexible flat cables will of course be part of the package as well (a longer standard length cable set, the PP05-L is available for purchase separately). For those looking for the best bang for the buck in high performance SFX power supplies, the SX500-G and SX650-G will not disappoint.
