SeaSonic S12 500W Power Supply
 

The Seasonic S12 500W PSU is a very good looking and powerful PSU. The
performance of the Seasonic S12 500W PSU is very good and stable as you
can refer back to the testing and performance section. The operation noise
level was very silent as well. There are four SATA connectors included as
well for supporting the SATA hard disk and dual PCI-Express connector to
support the SLI technology VGA card. With the price of around $139 US,
this was a good buy power supply unit if you are looking for a powerful
and nice looking PSU although it was slightly expensive than other normal
PSU.
