The Seasonic G Series 550W power supply fits well against the 360W unit in the same family. These budget oriented power supplies have not compromised in quality and the technical capabilities of the range we have looked at so far are certainly impressive.

Aesthetically the design is very simple. The plain black paint with simple stickers detailing specifications and branding is not intrusive. The paint is deep and can resist rough handling without leaving a mark, although it does tend to attract fingerprints quite easily. The understated design will suit a variety of systems, including those with Cathode lighting and side window panels.

Technically, the design is very capable and designed well to withstand heavy load variance. It also managed to deliver 650W before shutting down. Noise suppression falls well within rated tolerance levels although the G Series is slightly weaker in this regard compared to their other, more expensive series. That said, this won't really make a difference to the end user as the results are still excellent.

We mentioned in the previous review that the 360 wattage rating of the entry level G-Series power supply will unfortunately be enough to put off a large portion of the enthusiast audience. The G550 is starting from a higher base point which should guarantee good sales for Seasonic.

Additionally, the 550W model is only around £30 more expensive which is quite an achievement for a high grade 550W rated unit which is both semi modular and 80 Plus Gold Certified. This modular design makes it more appealing for media center fanatics on a budget.

We feel this is a very welcome addition into the new Seasonic range, and the asking price makes a potential purchase all the more palatable.

You can buy from Overclockers in the United Kingdom for £76.99 inc vat.

Pros:

• clean design.
• technically very capable.
• quiet.
• can deliver 650W under load.

Cons:

• A lot of competition at this price point.

Kitguru says: Another winner for Seasonic, and the price is right.
