Seasonic's S12G-550; you have to pay for prime power

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

2-S12G_Banner.jpg

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.

Seasonic PSUs Will Power HashFast Bitcoin Miners

Subject: General Tech, Cases and Cooling, Systems | October 22, 2013 - 07:10 PM |
Tagged: seasonic, Power Supplies, mining, bitcoin, asic

Seasonic (Sea Sonic Electronics) has announced a design win that will see its power supplies used in HashFast’s bitcoin mining rigs. The upcoming HashFast mining rigs feature the company’s “Golden Nonce” ASIC(s) and all-in-one water coolers. HashFast has a single ASIC Baby Jet and multi-ASIC Sierra rig. Both units will be available December 15 starting at $2,250 and $6,300 respectively.

The Seasonic power supplies are high efficiency models with Japanese capacitors and at least 80 PLUS Bronze. On the high end, Seasonic has PSUs that are up to 93% efficient. HashFast stated that it chose Seasonic for its mining rigs because of the build quality and efficiency. The Baby Jet and Sierra mining rigs allow users to overclock the ASICs, and the systems can be rather demanding on PSUs.

The Golden Nonce ASIC is a 28nm chip that is rated at 400 GHash/s and 0.65 Watts per Gigahash.

Beyond that, the companies have not gone into specifics. It is good news for Seasonic, and should mean a stable system for bitcoin miners (the 93% efficiency rating is nice as well, as it means less wasted electricity and slightly more bitcoin mining profit).

The full press blast is below for reference.

Seasonic's high quality 400W PSU, the X-400FL Platinum

Subject: Cases and Cooling | July 17, 2013 - 04:48 PM |
Tagged: PSU, seasonic, X-400FL Platinum 400W, 80 Plus Platinum, modular psu

A 400W PSU seems a little under-powered when compared to the kilowatt PSUs that are commonly reviewed but there are not many systems that actually need that amount of power.  Seasonic has designed their X-400FL Platinum 400W to provide great power, efficiency and extra features in lieu of providing huge amounts of power.  The PSU is fully modular and is able to provide an impressive 33A combined from it's four 12V rails, with an absolute minimum of ripple even during the most intense parts of [H]ard|OCP's testingAt $120 it is a little more expensive than other similar PSUs but with the outstanding build quality of the PSU it is worth it.

"This new Seasonic PSU touts Platinum efficiency, a fully modular design, and a host of other enthusiast-worthy hardware features that will ring true with those looking for a what might be "the best" 400 watt PSU on the market. For those of you looking to build that truly powerful HTPC, this PSU also offers silent operation."

Computex 2013 concluded on a high note for Sea Sonic to lay the foundations for yet another highly successful year for our company. At the exhibition Seasonic has continued its tradition to introduce new models of power supplies that provide innovative and high performance solutions for a wide range of users.

During Computex 2013, we were proud to showcase our brand new Platinum 1200W power supply, which completes our premium Platinum series now extending from the 400FL Fanless to the 1200 watts top end unit. Many power users who are looking for this ultimate, fully modular model of top performance and reliability will appreciate the Platinum 1200W. This third generation, mighty power supply is built from high quality components, providing almost perfect DC-to-DC power conversion and will be equipped with our advanced hybrid silent fan control.

Seasonic has extended its popular M12II series by adding a new EVO edition in 750W and 850W models. These new models are fully modular and will be supplied with aesthetic flat black cables to facilitate customized cable management for any user. Due to the employment of higher quality components, the manufacturer’s guarantee of the M12II EVO Edition will be increased to 5 years.

Besides our current S12II series and our highly popular G series, we will launch a robust lineup of 80 PLUS Gold certified family of power supplies, consisting of 450W, 550W, 650W and 750W units. This new S12G series will feature less molex but an increased number of SATA connectors and will be entirely outfitted with flat black colored cables.

We have further extended our embedded power supply range for our growing number of industrial users and we are constantly looking out to boost cooperation with our business partners to create specialized industrial solutions.

7 way PSU showdown; 550-600W weight class

Subject: Cases and Cooling | June 24, 2013 - 06:40 PM |
Tagged: TR2, thermaltake, seasonic, PowerX, in win, GS600, G Series, Dark Power Pro 10, CX600M, Cougar, corsair, Commander III, be quiet!

There is a roundup over at Legit Reviews, with seven 550-600W PSUs of which only two models will cost you more than $100.  They are a mix of 80 PLUS Bronze and Gold, some are partially modular others non-modular and of course, they offer differing power quality and acoustic performance.  In this case the most expensive PSU also came out as the winner, but pay attention to the PSU in second place which costs half as much as the Dark Power Pro 10.

"It is natural for an enthusiast to be dazzled by monsters such as the Corsair AX1200i and the Cooler Master Silent Pro M2 1500W; however, even the majority of the enthusiasts would not actually purchase such a beast. It is (or should be) common knowledge that even a very good gaming system does not demand more than 300W-350W and thus, as power supplies are being designed to optimally perform at about 50% capacity, 550W-600W units are plenty for the vast majority of gamers and common users. It is only with multiple video cards, large raid arrays and other “specialized” designs that power requirements may increase substantially. Knowing that and realizing the need to offer our readers insight on products which truly are of interest to them, today we bring you a roundup review of seven quality 550W-600W power supplies..."

Computex 2013: New Haswell-Ready PSUs From SeaSonic Pictured

Following Intel's announcement of new Haswell sleep states, various power supply manufacturers have released compatibility lists detailing which PSUs are able to deliver the low load necessary to support the power sipping sleep states on the 12V rail (which has not been much of a concern until Haswell).

One such PSU manufacturer was Seasonic, who has quite a few Haswell-ready power supplies across several lineups including its Platinum, G, and M12II series, among others. Included in that compatibility list were two new power supplies that Seasonic is showing off at Computex this week: the Seasonic Platinum 1200 and Seasonic M12II Bronze Evo Edition.

SeaSonic Platinum 1200

The Platinum 1200 is a high-end modular power supply that is capable of powering beefy multi-GPU setups. It is 80+ Platinum rated and is up to 92% efficient at 50% load.

Sesonic M12II Bronze Evo Edition

The Seasonic M12II Bronze Evo Edition is an updated version on past models and includes two SKUs that come in at 750W and 850W. It is a fully modular unit with flat black cables and fan control tech. It is 80+ Bronze and Energy Star rated, and is compatible with Intel's 4th Generation Core processors.

Seasonic Releases Information On Its Haswell-Ready Power Supplies

Subject: General Tech, Cases and Cooling | May 11, 2013 - 09:17 PM |
Tagged: seasonic, haswell, Power Supplies, PSU, 0.05A

Following the announcements from other power supply manufacturers, Seasonic has now released a list of its own power supplies that are compatible with Intel's upcoming Haswell processor. The new Haswell CPUs, set to launch June 3rd, incorporate new C6 and C7 sleep states that draw as little as 0.05A from the 12V PSU rail. Because of the low load, some existing power supplies will have issues with the new sleep states and could result in system instability. In light of that, many manufacturers are validating their existing lineups to determine which ones are compatible.

As of the time of publication, the following power supplies from Seasonic are compatible with Haswell and the new sleep states.

Platinum Series

  • 1200W
  • 1000W
  • 860W
  • 760W

The upper echelon of the Seasonic X-Series, 850W of solid power

Tagged: seasonic, Seasonic X-Series, 850W, PSU, modular psu

One drawback to impressing [H]ard|OCP with the quality of one of your PSUs is that the bar is now set that much higher for the next model they review.  Seasonic is one such company that has a great reputation that they have to live up to with their new X-850 PSU.  The half dozen PCIe 6+2 power plugs are a good start, as is being able to provide up to 99% of total power to the four 12V rails and the fully modular cabling is always appreciated.  The real question is how it fared on the test bench, so go find out if it just makes it or if it passes the torture test with flying colours.

H_X850.jpg

Seasonic is a long time favorite of HardOCP editors as you will find a Seasonic PSU in many builds we have done over the years. Today Seasonic pushes its X-Series forward just a bit more building its first gold efficiency rated fully modular enthusiast power supply. But will it blend?"
