Summary: This thing runs a 290x and i7 oc'd just fine. It's completely silent and cannot be heard over any of my other case fans, Cougars and Noctuas. Being modular it makes for a very clean case, and the flat cables are easy to stuff between the case and side panel.
Summary: I'd replaced two thermaltake psu's in the past that just quit. Finally replaced them with a 650w antec (antec are rebranded seasonic) and never had a issue since. So for my new build, I purchased this PSU. Plenty of power for my build: i4770k 16gb - ASUS maximus VI heero GTX780 4x SCSI3 HDD's 1x SATA 2x optical The gold rated efficiency claim I tend to view more as marketing since psu mfg's police themselves, besides, efficiency ratings only matter for over 80%...
Summary: Seasonic continues to be one of the best PSU manufacturers around. With power supplies, you tend to only notice them only when they've gone wrong, and I can say this has not been the case with my X-850. By keeping up a steady supply of current to my system, my Seasonic has become the silent backbone behind my rig. It's so quiet that I'll sometimes even forget that there's a fan on there! They'll continue to be a highly recommended brand!
Summary: I've been using it for 4-5 months with no negative issues. Radeon 7970, 3 HDs, optical drive. It had plenty of clearly labeled cables, runs very quietly, and has performed like a champ. Highly recommend.
Summary: I put my first system together using the ASUS Maximus VI Gene mobo, the Intel i7-4770k, 16GB(2x8) Corsair Vengence 1600Mhz memory, Seasonic 850w PS and the Silverstone Tek mid-tower case. It worked the first time I turned it and performs as advertised. I plan to add the EVGA GeForce GTX 760 graphics card and there should be plenty of power.
Summary: Was working great for the first 5 months, then it suddenly cut off while playing a game. My system should not be too much for it at all. Tried jump starting it and it turns on for a second each time, but then cuts off. RMAing now and hoping the next one does better.
Summary: Reemplaze mi fuente Thermaltake 600w por esta y me parece excelente, ademas todo viene muy bién y protegido, sus cables ordenados y el bolsas, en general estoy muy satisfecho. (google translator): Thermaltake 600w Replace my source for this and I think it's great, plus everything is very well and protected, your cables tidy and bags, overall I'm very satisfied.
Summary: If you are looking for a power supply to supply clean DC power efficiently while doing so silently or unobtrusively, this is the power supply line to get. I don't want a "flashy" power supply; it is supposed to be a utilitarian piece of equipment which the X-series most definitely is. Replaced a 650watt unit with this 850watt version but may not have needed so. I have an i7 2700k overvolted and overclocked along with 32GB of RAM and two 580 GTX cards in SLI.
Summary: Bought this to power my gaming rig in a BitFenix Prodigy case. It was one of the smallest 850w power supplies I could find, which is important for me trying since I was trying to jam it into the mini-ITX case. Plus it's a great brand: Seasonic and 80+ gold rated. Well, the supply fits in the case (barely) and runs like a charm. It's quiet and has no problem with the system, which was previously overtaxing/crashing using my 600w ThermalTake.
Summary: Well, after sinking $170 into a corsair PSU the other day, I expected to have all of my worries behind me. Surely Corsair makes a good enough product to stand the test of time, right? Wrong. I woke up the other morning to find it stone dead after only 5 days of service. I hopped on Amazon and got this one ordered as soon as possible. It arrived the next day, and I was thrilled to see it, once the box was opened. The cables are ALL black, not just the coverings.
