Seasonic G Series 550W Power Supply review

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.

  1. What about the 650W? that has 4 PCI e connectors. seems the best choice for a little futureproofing. all the rest only have 2 or 1 PCI connectors.

    Apart from that, these seem good value.

  2. excellent product, i need a new power supply.

  3. They make a lot of power supplies for companies. my XFX PSU is by them, and its been great.

  4. Looking for a high quality, capable PSU? Look no further than Seasonic.
