With an 80 Plus Gold rating and the ability to deliver 45A on its single 12V rail the 550W Seasonic S12G-550 PSU is perfect for a mid-range rig. A pair of 6+2 PCIe connectors gives you a choice of powering a single high end GPU or two low or midrange GPUs. It is also relatively small, barely larger than the 120mm cooling fan it uses though some may be turned off by its non-modular cables. At around $85 it is not the least expensive model at that wattage but [H]ard|OCP's Silver Award proves it is worth it if you want solid power for your system.
"Seasonic builds some of the best computer power supplies on the market. When do we ever get a power supply that is actually a better product than what it is marketed to be? Not often, but that is the case with the S12G-550 PSU. It is not terribly inexpensive, but it is a great value for your hard earned dollars."

Introduction and Features
We have been reviewing Seasonic power supplies for over ten years here at PCPerspective and they have never failed to impress us. Seasonic is also one of the few companies that actually builds their own power supplies (along with supplying units to numerous other big-name brands). Seasonic has built a stellar reputation for producing some of the best PC power supplies on the market today. In their ongoing pursuit to continuously improve their products, Seasonic has recently introduced the S12G Series, which includes four models: S12G-450, S12G-550, S12G-650, and the S12G-750 that we will be taking a detailed look at in this review. Here are a few of the highlights offered by the new S12G Series power supplies.
• 80Plus Gold certification
• Standard all in one, flat black cabling
• High +12V Output
• Smart and Silent Fan Control (S2FC)
• S12G-750/650: PCI-E 8P/6P x 4, SATA x 10, 4P Molex x 4, FDD x 1
• S12G-550/450: PCI-E 8P/6P x 2, SATA x 8, 4P Molex x 3, FDD x 1
• Worldwide 5-Year Warranty
The S12G Series is targeted towards gamers and PC enthusiasts who want solid performance at a user friendly price. To accomplish this Seasonic has designed the S12G Series on the same basic platform as many of their premium products but has forgone a few features like modular cables and fanless operation for price conscious consumers. Retail prices are currently ranging from $79.99 USD for the S12G-450 to $109.99 USD for the S12G-750 (newegg.com, November 2013).
Here is what Seasonic has to say about the new S12G Series: “The S12G Series is the newest addition to Seasonic’s families of award winning retail products, representing the latest innovation of our engineering team. To meet the demands of users who are looking for reliable 80Plus Gold performance for gaming and overall usage, the S12G Series is designed to support Intel’s Haswell processors, features more SATA cables and is an affordable solution for a wide range of applications.”
