Not only they design and market their own products, but they serve as the OEM behind the products of several other known brand names. Over the past year, the company has been renewing a number of their PSU designs, some almost completely. Among their new designs are the new top-tier 80Plus Titanium certified units and SFX format PSUs. Although we reviewed both of these products in the past and they have left us with very positive impressions, these are ultimately somewhat niche products and the bulk of the market lies elsewhere. So for today's review we're taking a look at SeaSonic’s latest mainstream market release, the Focus Plus Gold 750FX. As its name suggests, it is an 80Plus Gold certified ATX power supply with a maximum power output of 750 Watts. The Focus Plus Gold 750FX is at its core a product targeting the mainstream market, looking to strike a balance between quality, performance, and value. Power specifications ( Rated @ 40 °C )* AC INPUT 100 - 240 VAC, 50 - 60 Hz RAIL +3.3V +5V +12V +5Vsb -12V MAX OUTPUT 20A 20A 62A 3A 0,3A 100W 744W 15W 3,6W TOTAL 750W *There is a catch with the operating temperature of this model. SeaSonic rates it as operational up to 50 °C but de-rates its power rating down to 80% for temperatures over 40 °C. Therefore, we consider the Focus Plus Gold 750FX to be rated at 40 °C for its rated performance. Packaging and BundleThe Focus Plus Gold 750FX ships in an aesthetically simple cardboard box, with its artwork based on basic geometric shapes and focused on a black-gold color theme. Under the thin paper skin of the packaging, we find a strong cardboard box with the PSU well-secured inside it, providing ample shipping protection. Inside the box, we find a relatively rich bundle for a mid-tier PSU. There are a standard AC power cable and four black mounting screws, several cable ties, three black/blue cable straps with the company logo printed on them, a case badge, and a basic user’s manual. As the SeaSonic Focus Plus Gold is a fully modular PSU, every cable can be detached, including the 24-pin ATX cable. All of the cables are completely black, made of black wires and black connectors. The smaller SATA/Molex power cables are ribbon-like, or flat-type, but the larger PCI Express and CPU 12V connectors are made of regular wires covered in black nylon sleeving. The Seasonic FOCUS Gold 750W is a high performance PSU featuring super compact dimensions, a fully modular design and a selective semi-passive operation. All above can be yours at a very good price which doesn't exceed 100 bucks and the cherry on top is the ten-year warranty. If Seasonic manages to improve the not so good 3.3V transient response and lowers the output noise, the FOCUS units will be even better. Pros

Features & SpecificationsSeasonic's Prime Titanium, Platinum, and Gold families are already available, and the company still isn't done: we're now looking at its Focus series, consisting of the Focus Plus and vanilla Focus. The aforementioned Prime models are mostly aimed at enthusiasts, while the Focus units target value-oriented buyers. According to Seasonic, its Focus Plus and Focus PSUs will eventually replace the popular G and S12G designs. With the release of its Focus models, Seasonic is implementing a new policy that should make evaluating its products more transparent. From now on, reviewers will only receive Seasonic samples from online vendors, rather than the factory. While we do see ways this system could be gamed, implemented properly, it's a big step forward in ensuring reviewed hardware is representative of what readers will find on store shelves. Why didn't anyone think of this sooner? The fact is that most companies want to check the samples sent to reviewers first. Some manufacturers go a step further and only ship off their best-performing products, which then come to be known as golden samples. Of course, we understand the desire to make a good impression, but this practice becomes problematic if retail hardware is found to have issues not seen in reviews. The Focus Plus Gold line consists of four members with capacities ranging from 550W to 850W. They're all 80 PLUS Gold-rated, certified by Cybenetics for ETA-A-class efficiency, and equipped with fully modular cabling. The model we're testing today is the SSR-750FX, Seasonic's 750W implementation. It's a mid-capacity PSU suitable for use in a capable gaming system with a couple of high-end graphics cards and an overclocked CPU. SpecificationsSeasonic arms the SSR-750FX with a full complement of protection features, and it rates the unit for continuous full load delivery at temperatures as warm as 50°C. Unfortunately, the 120mm cooling fan is a little small; this plays a major role in the noisy operation under taxing loads and high ambient temperatures that we measured. Then again, the chassis' compact dimensions limit Seasonic's options. A 135mm or 140mm fan simply wouldn't have fit. According to Seasonic, it uses a fluid dynamic bearing-based fan, so it should last a long time. The fan is supported by a semi-passive mode. Of course, we're big proponents of long warranty periods, so long as they're realistic. Seasonic's 10-year coverage is a result of the company following its competition, even in this mid-range category. Finally, the dimensions of all Focus Plus Gold PSUs are very compact, given a mere 14cm depth. To the best of our knowledge, only SilverStone's ST85F-PT matches Seasonic's power density score.

The 5VSB rail has a 15W capacity, so it is a little stronger than what we'd expect.

Power DistributionSince this PSU features a single +12V rail, we do not have anything to say about its power distribution.

fredlaso Dell Inspiron 5675 Desktop, PSU (power supply unit), upgrade. Would this PSU compatible with Dell Inspiron 5675 Desktop. It came with 460W I would like to replace it with PSU between 650 to 750W. I tried at Dell forums but cannot get a clean link which one would be compatible. |
