A fine replacement for the G-series
This is an excellent power supply for a system with one powerful graphics card or two mid-range cards. A lighter system would be better-served by a version of same with lower wattage.FEATURES: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.PERFORMANCE: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.IN SUM: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.

Highly rated PSU with a long warranty
It’s hard to review a PSU because when everything works right you don’t notice the unit (unless you have expensive equipment to test the unit). So far I have not had any problems or complaints with the unit, the unit is compact and fits inside my smaller case, the labels on the unit/cables were clear and easy to identify. The cables themselves are quite stiff but having worked with a handful of PSUs this is fairly typical. The fan is not audible / I cannot hear the fan since my case fans are the only thing I can hear.As for the reputation of this brand, Seasonic PSUs have the reputation of being some of the best on the market. If you search for “PSU tier list” such as the one on the LTT forums, you will find that many of the Seasonic models are towards the top. They are rated highly because they are reliable, efficient, and high quality. Throw in a 10 year warranty and there isn’t much to worry about.I bought this to replace a PSU that had awful coil whine and happily this unit produces no audible noise in my build. Worked right out of the box with no troubleshooting required. Huge improvement already. Haven’t had it for very long so I’ll update this review if I encounter any problems with the unit. So far so good.

One of the best 1000 watt units built.
There is a review on this unit that reveals the fan, a very high quality fluid bearing fan that is nearly inaudible, sells for $25 by itself.This is one of the most quiet designs, not just from the standpoint of audible noise, but of ripple in the output power. This design is very quiet and stable even when abused.The 80plus rating says nothing of the truth. At half power, where you should run a power supply most of the time, this unit is well over 90% efficient.The cords, ties and supplies are generous. You get a wide range of cable options for a clean build.

Great Quality and good pricing
I’ve been using Seasonic power supplies for over 10 years in lots of PC’s and servers. Can’t recall any failures… ever. One word of caution, don’t buy more wattage than you need. It’s a waste of $ and electricity.

This is the best PSU I ever come acorss in my life !!!!!
While I have had the unit in operation for just a short time, it is performing very well. What I want to focus on in this review is the design of the unit.First off being the footprint, I have a similar wattage power supply that I had intended to use in this PC build but it was too big in one of the dimensions to be able to fit in the case next to my radiator. This is what set me looking and I went right to Seasonic as they are in the top two of my power supply vendors. I was extremely pleased to find that this 1000W power supply is a good inch smaller than my other and fit the footprint bill well.Add to that the fully modular cabling which makes it so much easier to work in the still-limited space remaining and that brings up the second focus of my review, the cabling that is included. The lengths and arrangement of the power connectors on the many included cables covered all of my needs from SATA to water pump to dual CPU connections. The installation was a happy one because of the design, and the performance so far (just a little over a week) has been what I expected from a top name, top of the line PSU.I would also add that I was happy to find that the labeling of the connections and the external side were unlike the photos I had seen, and came out “right side up” with the fan mounted down as in a bottom mount with air intake from the filtered bottom of the case. That’s just a nice looking addition to the overall appearance of the system.

Solid and Quiet
This thing really is low-noise. Most of the time it’s hard to tell if my PC is ON. Seems to deliver all the power this PC needs. The only real concern is longevity, and that’s hopefully something that won’t be known for a long, long time.

Seasonic es fabricante propio de fuentes de alimentación para PC a diferencia de otras marcas como Corasir que no las fabrica sino que las subcontrata. Llevo casi 5 años con ella y funciona como el primer dÃa, silenciosa y fiable. Recomendada.
Tech Watchdog –
Seasonic with a 10 year warranty, nice looking plain black modular cables and super quiet under load even with overclocking. Highly recommend.
Nebu –
No cons. Working fine about four months in.

I like that it is extremely stable and noiseless most of the time. The only con is that the 20/24 pins MoBo connector is almost impossible to bend, the heat shrink tubing added to keep the individual wires together at the end of the cable is too hard to bend. This makes the installation a little bit difficult. Everything else is perfect.

Seasonic es la marca de fuentes de poder en que más confÃo y la única que recomiendo.Alimenta sin problema a mi procesador y dos GPU.Esta PSU es tan eficiente que el ventilador o no necesita encerderse o si lo hace es tan silencioso que ni siquiera podrÃas notarlo.Es modular, lo cual es una gran ventaja, conectas sólo lo que necesitas o si necesitas (como en mi caso) más conexiones para PCI-E las agregas sin problemas y sin limitaciones.Su apariencia es me gusta, es muy discreta y su diseño es simple, esto me agrada pues asà destacan otros componentes como la GPU.El único “detalle” es que sólo trae 3 cables para PCI-E, de forma que si, al igual que yo, requieres varias GPU de manera simultánea tendrás que comprar más cables.Recomiendo mucho esta PSU.
