Seasonic products are, in general, meticulously designed and really good performers. After all, this company has been in this field for ages. They, naturally, have a lot of experience in making PSUs, which is their only and main purpose. The only downside of most Seasonic products is their somehow high price. Especially their high-end models are expensive. Thankfully, most likely due to the tough economic times, Seasonic decided to follow the currents and designed an affordable series with high-end characteristics, allowing users to equip their systems with a high-performance PSU that won't cost them a fortune. The G-550 left me very satisfied with its overall performance and build quality. Clearly, Seasonic made very few compromises in component selection, allowing for high efficiency, tight voltage regulation, and excellent ripple suppression. Only the hold-up time is a little smaller than what ATX spec recommends, but that alone is not enough to spoil the overall good impression of the G-550. Nevertheless, I would like to see this unit equipped with four PCIe connectors instead of only two. I know that Seasonic addresses the mainstream user with this unit, but I would have still liked some extra headroom for a dual PCIe graphics card setup.

To wrap up, the G-550 is another excellent product from a company that has a strong tradition in this field; a company that provides excellent after-sales support which is crucial to all future buyers. Surely, the G-550 meets some strong competition at this price point, but, judging from all test results, I can tell you that it is worth every penny. You should seriously consider the new Seasonic G-550 if you need a medium capacity PSU and are covered with two PCIe connectors.
