      Good day: Power Supply shipped fast, Packaging of the power supply by Seasonic is First Class,Wow!! They Pad the supply so shipping will be no problem when you get it, MSI 970-Ga 43 Mother Board, does not like the Hybrid mode of the power supply, my mobo shut down and seemed like the power supply had failed. Glitch in the mobo, not power supply, Flash Bios and don't run supply in Hybrid mode. Stiff Power to mobo cable, Instructions are clear and straight forward. Only use the the provided Screws to mount supply to case. Quiet in full run mode and gives the power, Price over the others to me = More Bang for the Bucks. Contacted Support, response was fast. I run 3, 2TB Hd's 2 Windows O/S and a Linux O/S in and out all the time, system is on and running days at a time. This is the power supply for the person that works a computer, 5 Stars.
      No I am not paid or anything by amazon, I had a very fine 850 Watt for many years that blew and wanted and felt a 1000 Watt would be a good replacement. The few reviews on this one were all spot on. you need power at a good price, I say this is the one to buy and buy from this company.

      Fabulous PSU. Only thing I don't particularly love is that you cannot use any other cables than Seasonic ones, and Seasonic cables do not work with other PSUs. Found this out the hard way and had to wait an extra 4 days for new cables to come in. Well worth the wait however.

      Originally bought a corsair psu as i love the company and thought the quality will be there. Built a new Ryzen PC with the corsair psu and the same day could hear coil whine. I thought ill grow over it but the coil whine got even louder when i fired up Battlefield 1. So i went on forums, different reviews, etc to see who makes the best reliable psu. Seasonic came as like the gold standard (no pun intended) when it came to recommendations. Ended up with this psu seeing as how well it was getting reviews, the materials used in it and the long warranty from seasonic. What can I say, installed the psu and its so quiet!! Granted its only been the first day but man its a night and day difference between the corsair and seasonic. It is pricey but its totally worth it. Always gonna choose seasonic from now on for any new pc's i build.

      This PS powered an ASUS ROG STRIX X399-E GAMING board for about 2.5 years with 96GB memory. I use it for parallel builds of complete systems for both work and my own projects. Last week I heard a POP and the board started shutting down randomly without warning. Rebooting would work for awhile followed by random shutdowns. Now the mobo won't boot at all. I've replaced the PS but the board still doesn't boot anymore. The PS also doesn't boot a new mobo but a new PS does.

      I seldom have problems with PS's or mobos - they tend to last me 5-10 years. 2.5 is not a good value for a higher end component.

      Great power supplies in general come from seasonic they make a lot of them, some even for other companies. And right now they are giving away a blutooth speaker with their gold prime 850 and up power supplies. So I am writing this cause of that, but really Seasonic is my goto power supply anyway. Never had a problem with their units and I expect the same from this, as it has a 7 year warranty!!!

      Good quality, no noise, nice no fan button on back. Good customer support answered by question. Only complaint is the cables are very stiff, especially the 24pin is hard to bend for management. Comes with all the cables I needed, great price and amazing warranty, 12years jesus.

      La mejor marca de PSU, estas bellezas soportan todo, apagones, corto circuito, variaciones de voltaje, incluso si las conectas a un no break de onda simulada. La fuente no prende si un componente está descompuesto una función muy buena. Venía de usar una Corsair rm850x que la verdad es una basura. Seasonic mis respetos. Si la conectas a un no break que sea de onda pura compatible con PFC!!!!!!!!

      Reviewed in India on September 5, 2019
      Style: SSR-850GDVerified Purchase
      -Initial Impressions-
      As most PSU's in this price range/wattage offer the same or exact specs, there's something about a Seasonic that is different. The understated looks, bullet proof casing, the paint finish on the product, noiseless fan, wonderfully crafted and well spaced cable sockets. Tank like build quality that's built to last!

      It's a shame that this beautiful thing will spend the rest of it's days tucked inside a dark corner of the PC case!

      -Package-
      Twin cardboard boxes with perfect bubble wrap got these home to me in perfect condition. Well packaged!
      The PSU itself sits inside a velvet bag (inside it's box), with the usual documentation and accessories.

      -Cables And Accessories-
      Did I say it comes with a bunch of cable ties? These come in very handy at every stage of the PC build. The stock cables are on the stiffer side of things, but not a worry if you have enough space for cable management - I use a Lian Li PC-011D so I did not have problems with cabling. These would be a problem on smaller mid-tower cases NZXT Elites, Corsair Carbides etc only if you're squeezing the back panel shut. It also comes with a nice metal badge if you wanna stick it on your case to show which PSU you're using :)

      -Overall Expression-
      Very happy with the purchase. I've been using it for the last two months and the PC booted in the first attempt. I did not want to shave off money from one of the most important components of the PC - The PSU! Had to get a Seasonic! The seller is the only authorized dealer for Seasonic PSUs in India.
