Unlike most of the power supplies we sell, this Seasonic unit does not have a side-mounted 120mm fan. The 80mm rear-mounted fan it uses instead is often necessary in low profile and rackmount cases, were there is no room for airflow to the sides or top/bottom of the power supply.

Christopher Crader (Customer Support) Says:
This is a good, reliable power supply. Not much else to say. It's not a powerhouse, so don't expect to use it on anything higher end, but if you've got a pretty basic system, this should be adequate.
