The Seasonic G Series 550W Power Supply is finished to the same standard as the 360W unit in the same family. It is plain but will look fine in a variety of systems with side panel windows. The same high quality paintwork is present, although it does attract fingerprints quite easily.

A large 120mm fan takes centerstage at the top of the chassis, hidden behind a black protective grill.

The rear of the chassis features a honeycomb vent panel next to a power connector and switch.

The modular cables all connect into a single panel on the opposite end of the chassis. These are not labelled, although the cables can only fit into specific ports, being 3+3 pin and 4+4 connectors.

The range of G-Series units, shown above. the G-550 unit can deliver up to 45A on the +12v output.
