Seasonic Prime 850 Titanium, 80+ Titanium Certified 850W Full Modular Power Supply with 135mm FDB Fan Power On Self Tester

I ran a COUGAR GTX1050 almost constantly from 2011 until now. That PSU ended up going out with a bang and a flash. Just under 8 years of life. It was a solid enough power supply, had a decent lifespan, but only carried a 5 year warranty. I had no idea as to whether it took out my build or not. Regardless, I knew I would need a new PSU. I decided that I'd go for an even *more* efficient PSU this time around. That one was GOLD rated; so I figured I'd step up to the highest that exists now, TITANIUM. My current setup doesn't require a huge power rating, but I figured that it doesn't hurt to run a PSU at a lower wattage than it can handle. Plus, you'd have room for expansion. Beyond that, I wanted something that was quieter.After hunting around for quite a while, I decided on the Seasonic SSR-1000TR. The warranty that Seasonic has is industry leading. I thought about going with Corsair since I have some other components from them. I believe that the few additional features that those comparable PSUs had would just end up being additional points of failure.This PSU was stocked by Amazon, and came quickly and safely. The unboxing experience was quite nice. The fit and finishing of the packaging and components themselves is quite above what I'd ever expect out of something that's going to not exactly be in the limelight in your case. Plenty of cabling, which seems to be nice wiring with nicely molded connectors. All of the wiring that I won't be using at this time will live in the velvety bag that Seasonic provided. Plenty of cable management straps included as well.Once installed, my system booted right up. (So, I was pleased that the other PSU didn't fry components as it went out.) My computer appears to be a bit quieter now. I believe that my storage drives are probably the loudest bit now. The Hybrid system will be nice. This allows the fan speed of the PSU to be ramped up/down according to thermal needs vs just 100% all the time.So far, very pleased. I plan to hook up the computer to my kill-a-watt and see the power factor, etc. Hopefully I won't ever need to use Seasonic's warranty. If I did need it, I don't feel that it'd be a hassle.

The Seasonic PRIME Ultra 850 Titanium (SSR-850TR) came in a package fit for a premium power supply. The unit is fully modular and comes with plenty of cable connections (and cables). The fan is 135mm and operates in two modes: quiet and dead quiet (controlled by a button on the back of the unit). Build quality is excellent and so far, the unit is performing perfectly. All this, and a 12 year warranty, too. Previously, I had the Silverstone Tek Strider Gold S Series 750W ATX12V/EPS12V 80 Plus Gold Full Modular PSU Power Supply ST75F-GS installed, but a capacitor began to fail after a little over four years of use. The difference between the two power supplies is like night and day - the Seasonic one has a much larger fan, which will be most appreciated during the summer months, and is way quieter to boot. I've liked Silverstone, but am pleased I made the switch.

I bought this to replace a 10yo 750W Seasonic that finally bought the farm. It owed me nothing, and I trust Seasonic completely. I am an electrical engineer, and have pulled their stuff apart before. The circuit topology is well thought out, and the components really are of a very high quality. You can tell these guys know what they are doing when it comes to minimizing ripple, current foldback, and being able to provide stable power as the system demands it. They are such a high quality that the other trusted brands - like Corsair and EVGA - are usually just re-badged Seasonics for their high-end stuff.I went with a this larger supply simply so I could take advantage of the higher efficiency. PSUs are always more efficient the less power you draw from them. I am normally drawing around 500-600 watts at peak, and 300-400 at idle. On my old 750W supply, that meant I was around 85% efficient at peak power usage, and 90% or so at idle. With this new one, I will be around 94% efficient at peak power usage, and about 93% efficient at idle. So, all around, I should see a slightly reduced electric bill from this more efficient PSU.The only thing I am going to knock them for is their documentation, specifically the lack thereof. With my old middle-of-the-road 750W Seasonic, every single cable had a detailed page documenting the pin layout on both ends of the cable. With this high-end 1KW Seasonic, I got a list of included cables and their lengths, and suggested cabled hookups ('Use two PCIe cables for cards requiring over 225W' is an example). I could probably figure it out on my own, but having that pinout is nice for troubleshooting or if I ever want to sleeve my own cables. At least some online documentation would have been nice. Ultimately though, not enough to knock off any starts.

Fantastic build quality! Even the branding is made of finely machined metal with a mirror finish. The optional passive cooling mode is a great feature for those who demand a silent PC build and the standard fan cooled mode works quietly as well with no audible noise at a meter away. The power output is very stable and at my load of around 350W the power efficiency is better (>4% improvement) than my previous Platinum rated power supply! For around the clock usage (or even 12 hours a day) this adds up to a cheap electric bill and improved thermals (less waste energy as heat).Highly recommended Power Supply!
