Seasonic engineers have created a brand new product line based on advanced technology emanating from many years of intensive active research. The result of this development is the solid FOCUS+ Series, which implements modern design and shows outstanding electrical performance. This power supply is small and entirely modular, which will be hard to resist. It is available in 80 PLUS Platinum efficiency ratings.
Legal DisclaimerThis power supply is only compatible with cables provided by Seasonic. Any other cables not approved by Seasonic will result in item malfunction.

First off, its a beautiful power supply, this PSU has a thick applied powder coat of matte black paint, that will not scratch. It has a professional, non-flashy finish, that will blend beautifully into whatever build you decide to install this PSU into.
This product is fully modular, allowing the user to install only the power cables he/she needs, and none that they do not. Everything is built onto a single 12V rail, so there will be no concerns for the user regarding load balancing. Additionally, this power supply comes with a 10 year warranty against manufacturing defects, which is industry leading, and shows the confidence that Seasonic places into this product.
Finally, the power supply came with a feature that I have never seen before, and that is a switch that activates the Seasonic Hybrid Silent Fan Control. This switch, when activated, puts the PSU fan into 3 phases: fanless mode, silent mode, and cooling mode. This allows the user to lower noise in their chassis without reducing power delivery. And when this power supply delivers 90% efficiency at 50% load, you'll likely never hear the fan.
This is a fantastic piece of equipment for any modern gaming computer, HTPC, or mining machine. I have purchased numerous Seasonic power supplies in the past, and i continue to be impressed with their product quality. With a 10 year warranty, and a professional, reserved look, its hard not to recommend this series of power supplies to anyone looking to build or update a new system.
The cable layout is like so:
1 x 24-pin motherboard (sheathed)
1 x 4/8-pin CPU (sheathed)
2 x 6/8-pin PCIe (sheathed)
2 x 4 SATA (not sheathed)
1 x 3 molex (not sheathed)
1 x floppy (not sheathed)
This is a fully modular power supply. Modularity means that some or all cables are attached separately so you can pick and choose what you need. This feature becomes more important as wattage goes up so you won't obstruct airflow with unused cables. The cable attachment mechanism is nice and chunky; better than flat inserts that put all four wires in line.
Fifteen years ago, most power supplies were about 70% efficient: for a 100W load, they'd pull about 140W from the wall. Not anymore. We now have six major PSU ratings: 80 Plus and 80 Plus Bronze, Silver, Gold, Platinum, and Titanium. These correspond to half-load efficiencies of 80%, 85%, 88%, 90%, 92%, and 94%. Efficiencies at 1/5 and 4/5 load are about 4% less than half-load. This unit is Gold-rated, and according to PCPer, meets the 90% efficiency requirement for that certification.
There isn't a strong economic argument for efficiency. Relative to a Bronze PSU, the FOCUS saves about $5 a year for a 24/7/365 100W load in most parts of the country. More noticeable is the acoustic difference. Every watt that isn't going into the system needs to be vented from the PSU. Less efficient units require a bigger or faster fan, which makes more noise. The fan in this one doesn't even turn on until a 200W draw and doesn't begin to ramp up until 400W. For the overwhelming majority of systems the overwhelming majority of the time, it'll be completely inaudible.
I haven't commented on ripple and other low-level power characteristics, partly because they're exemplary (par for the course for Seasonic), but also because they're irrelevant. Short of a no-brand $15 tin-box special, just about every PSU on a retail shelf is good enough for a modern system if the wattage is adequate. Computers require less power than they ever have (outside of gaming and overclocking) and motherboard power regulation is better than ever. This FOCUS has no bad behaviors under load, but you could put a $30 Corsair in your system with nary a difference.
This is an excellent PSU for a system with a serious graphics card, and where noise performance and efficiency are at a premium. It's also rather well-priced like the G-series that preceded it. I've had at least four Seasonic power supplies. None have failed. None have had coil whine or strange fan behaviors that I've seen even on high-end models from other brands.
While Seasonic is an OEM for other manufacturers, I believe their own products represent the best they can do. As above, I don't think this level of performance is strictly necessary, but if you're willing to pay for it, you could hardly pick a better PSU. Just run your system by PCPartpicker's excellent power calculator before settling on a wattage.
I've been building PCs for well over 10 years, and have always found funny how some Builders cram the highest powered PSU their budget allows into their PC. That's not how it works.
You need to know approximately what's the peak power of the PC you're building. Reason? Efficiency. Efficiency suffers the most when a PC is pulling a small amount of power (eg: idle, web surfing, music, youtoubing, office, etc). The lower the percentage of load you're pulling from the PSU from it's total, the less efficient it is, the more money you're not saving on the electricity bill. That's why office PC usually have a 250W-300W PSU.
Secondly: don't bother with 80Plus Platinum/Titanium PSUs just yet. It's 2% and 4% more efficient than Gold at 50% load, but usually come with a hefty price premium over Gold certified PSUs. It would take a lot more years to get the Return on the extra investment, than what you're probablly going to keep the PSU.
With that off the table, let's talk about the PSU. This device is powering an Intel Core i5 based system, overclocked to 4.0GHz, 16GB of RAM, one SSD and one HDD, 5 fans and a GTX760. It has power to spare, while being EXTREMELY quite, and exhaust air is relatively cool compared to older PSUs when gaming.
The cables are flat, which are a godsend for cable management within the case, and a pouch for those extra modular cables you won;t be needing. Comes with a rather large sticker.
Why Seasonic and not higher named (Seasonic is not small by all means) brands like Corsair, Antec eVGA or similar? We can't generalize, but keep in mind that SeaSonic is one of the OEMs for many of the PSUs from those brands. They rebadge, relabel and rename the units, and sell them usually more expensive, adding little to no value. Save yourself a couple of bucks here.
