Seasonic PRIME Ultra 850W 80+ Titanium Power Supply

Hail the tight voltage regulation, quiet operation, 80 Plus Titanium certified efficiency, high-quality components and full modular design. Robust power will be delivered to your PC reliably, silently and efficiently even in extreme conditions.

Features
  • Ultra-High Efficiency, 80 PLUS Titanium Certified
    The Seasonic PRIME Titanium 80 PLUS Titanium certified power supply is rated to achieve 94 % efficiency at 50 % system load.
  • Super-High Efficiency, 80 PLUS Platinum Certified
    The Seasonic PRIME Platinum 80 PLUS' Platinum certified power supply is rated to achieve 92 % efficiency at 50 % system load.
  • High Efficiency, 80 PLUS Gold Certified
    The Seasonic PRIME Gold 80 PLUS Gold certified power supply is rated to achieve 90 % efficiency at 50 % system load.
  • Fully Modular Cabling Design
    It is a flexible solution that optimizes cable management and reduces clutter inside the computer case.
  • Micro Tolerance Load Regulation (MTLR)
    Seasonic's latest design keeps the output voltage within a very tight range, achieving under 0.5 % load regulation. This impressive electrical performance and stability makes this power supply an ideal choice for high-performance systems.
  • Top-Quality 135mm Fluid Dynamic Bearing (FDB) Fan
    The high-pressure oil between the FDB's drive shaft and bearing sleeve reduces friction and vibration to increase product lifetime and reliability. The 135 mm larger-sized fan allows for reduced fan rotation speed while maintaining optimal cooling.
  • Premium Hybrid Fan Control
    Sea Sonic's vast experience in designing the most silent power supplies on the market was translated into the development of a state-of-the-art fan control to keep the overall fan noise at a lowest possible level for an undisturbed user experience. The industry's first, advanced three-phased thermal control finds perfect balance between silent and cooling through three operation stages: Fanless-, Silent- and Cooling Mode. Users can manually select between the Seasonic Standard Mode (fan control without Fanless Mode) and Hybrid Mode (fan control including Fanless Mode) settings with the help of a selector switch found on the back panel of the power supply.
  • Cable-free Connection Design
    Seasonic's engineers have implemented a new design feature, where instead of cables, the back panel and PCB (Printed Circuit Board) are connected by a copper plate. This breakthrough solution not only lowers the chance of production errors during manual insertion but it also improves output power quality.
  • Super-Low Ripple Noise (under 20 mV)
    Seasonic's continued commitment to excellent analog power supply design has resulted in the suppression or ripple noise to a level well below the current industry average of 20 mV.
  • Highly Reliable Aluminum Electrolytic Solid Capacitor
    Top-grade, Japan-sourced components extend product life and ensure operation stability under extreme conditions.
  • Gold-Plated High Current Terminals
    Reduces current transmission resistance and increases efficiency.
  • Multl-GPU Technologies Supported
    8-Pin and 6-Pin PCI-E connectors support all GPU platforms.

Better than expected

Overall Review: Honestly I'm only writing this for the Steam card, but being stationed in Japan and by the time the post office rowed it across the pacific the first thing on Seasonics registration page is the Steam card offer has expired. But I figured what the hell, I'm already here...

I think this thing is great!
Normally I'm a corsair guy... but lately corsair just isn't blowing my skirt up, I think they have been going down hill for years now, mainly in the power supply department - I'd still use their RAM though.

Back to this thing... I haven't had any problems, no noises, whines, anything... granted it's still pretty new and been installed for only a few days. I was a little worried with some of the reviews talking about noise and whines and other nonsense... but after years of using a corsair power supply, this baby is like a ninja tiptoeing on pillows... or I'm just deaf... but since I can hear the keyboard as I'm typing this, I'm thinking my hearings fine.
The ONLY thing I can think of at this moment that I did NOT like about this and the reason I gave 4/5 stars/eggs/whatever... is the flat cables. The main motherboard supply cable has a really nice mesh sleeve, but the rest are all just flat plastic. I'm not snobby when it comes to price, but I don't have a ton of cash to throw around either, but in my mind, for the price point - the black sleeves on all the cables should at least be an option.

Well there you have it... I think this things great even if I'm not getting my $25 steam card :-p
I don't know what to say to those talking about the whining in other reviews, maybe it's different for everyone? Maybe don't stick your head in your case? I don't know lol

The BEST PSU you can buy.

Pros: This is pretty much the best PSU you can get... great fit and finish, very efficient, 12 year warranty. Basically once this is installed you can forget that it is there... which is the ultimate testament to its quality.

Cons: none

Looks Really Good

Pros: Registration was easy; Lots of cables; Twelve year warranty; Nicely packaged; I think I saw it wash it's hands and try to make me a sandwich; I may have dozed off on that last one....

Cons: I can't imagine...

Overall Review: My girlfriend, (Lisa K.) bought this for me for my birthday and said if I didn't love it I shouldn't get it. Another reviewer had a Seasonic for ten years with no problems and bought another just for the upgrade. I've had two cheap PSUs go bad on me within a few years and I expect this PSU to be quite different. If there are any issues I'll report back but I don't expect any. Tom S.

Awesome Powersupply

Pros: Pros:
-Packaged extremely well.
-Plenty of connectors.
-Comes with a power supply tester.

Cons: Cons:
-none

Overall Review: After searching for a new power supply and reading many reviews I settled on the Seasonic Prime Ultra 850 Titanium model. Just upon opening the product you can tell by the way it is packaged that they care about their product and it screams quality. Easy to install and swap out my existing power supply. My case looks much neater now due to the modular design of this power supply. (I don't have a whole mess of cords tied in a bundle anymore, just the cords I need)

Seasonic PRIME Ultra 850w

Pros: -Quiet.
-Cables have good length. Especially 8 pin CPU cables. My last supply (also a Seasonic) had some short 8 pin CPU cables and was forced to use an extension.
-A good number of cables.

Cons: -None really, but I do have other thoughts.

Overall Review: The 24 pin motherboard cable could be longer. I have a large case and while it does fit it is kind of a stretch. If you have a large very large case and 24 pin power port on your motherboard is at the top (or at least towards the top on the side) you might need an extender. My case is a Corsair 1000D though.

It's been running fine for about a week, my last supply was a Seasonic and it's been in use for about a decade, so it was time for a replacement. My last power supply before that died and took the motherboard, processor and RAM with it, so after that I decided to look for the best power supply on the market, since then I've used Seasonic and have nothing but positive things to say.
