Cabling Arrangement

Since the ST30SF is only a 300W power supply, the cable summary isn't going to be incredibly long. The ST30SF gives just enough to get the job done, and there isn't any reason for anything more. There is a single PCI-E connector, which means there are a large number of GPUs that you cannot use with this power supply. There are three SATA and two Molex connectors, along with a single FDD connector if there is anything still in existence that requires it.

Rail distribution is as simple as it gets with a single 12V rail. There is no need to worry about load balancing here.

A Look Inside

Saying that the ST30SF is small is an understatement that becomes even more apparent when opened up. A simple bent piece of aluminum acts as a heat sink, but it's more than sufficient to get the job done.

A single Teapo bulk capacitor sits on the primary side of the power supply.

The secondary side is littered with a grab bag of Taiwanese caps.

SilverStone uses the Protechnic MGA8012XB-A15 80mm fan to provide active cooling.
