Got way more than I paid for! 5/13/2020 11:48:13 AM

Pros: Super high quality cables, and lots of variety
Install was straight forward an the modular design is well thought out
looks and sounds great! (no noise)
The way the box contents were laid out felt like i was getting a premium product, the cables were in a separate bag, the case badge is really nice, and the layout was really organized.
It is super quiet and you can tell the moment that you take it out of the box, you have a great product!

Cons: --price? WHATEVER!!! this is the right price for what they are offering ... if anything it is a steal!
--Modular design -- the Motherboard connector on the top. the PCI in the middle and the SATA/MOLEX on the bottom. Why is this a CON? Well when running cables, I usually start with the biggest to the smallest. So I start with the MB and then the Proc, Video Card, and then Drives / other.
So when routing you have to unplug the Motherboard to install the PCI, and unplug the PCI to plug in the SATA. No big deal, but with bottom mount... I would say that is a con.

BUT!!!! I would surmise that I may be able to turn it over, so this may be a user error?

Overall Review: Cables are high quality, and there are so many options! I was able to do almost what felt like custom length cable management for my case and Motherboard! (GIGABYTE GA-990FXA-UD3 and Cooler Master Storm SGC-5000-KWN1)
My case has the Power supply on the bottom, and a ICYDOCK 2.5' Drive bay at the top, that is a LONG cable run for a MOLEX lol but, there it was ! right in the bag and just the right length!

As far as performance goes, working great right out the of the box and no issues!

Would I recommend this? Depends.... the 850 turned out to be WAY more than I needed. could have gotten a 650 and been fine. So I *WOULD* recommend this power supply series to anyone and everyone! BUT .... You should go to Seasonic's website and there is a 'Wattage Calculator" this is really specific component level stuff! It showed that I could have gotten away with a 650, but I did not find out about this until I went to register the power supply.

So does that mean that I will return it??? HECK NO!!! this thing is so nice! I have another build that I am working on and will use this 850 there, I will buy the 650 then and since it is modular, it will go in a snap! (literally lol)

Thank you Seasonic for being a shining light among all of the power supply manufactures that are more interested in price than quality. You guy's are awesome and should be really proud of this product!

Excellent 5/5/2020 5:19:45 PM

Pros: PC runs smoother quieter and seemingly cooler

Cons: Does not work with corsair pro cables because of the sensing

Overall Review: So far so good minus the 1 hiccup I had thinking it was dead on arrival because of my corsair individually sheathed cables with built in capacitors.

DOA 4/29/2020 8:51:08 PM

Pros: Looks good on paper, impressive even in person.

Cons: Price, but, the market is in flux at the moment with the pandemic affecting supply chains. Besides, if this thing can do what is says it can do and the one I got was a one-off bad unit, it'll be worth the investment.

Overall Review: Powers on and then shuts right off immediately. Makes a slight sound like a circuit breaker or relay resetting when it shuts off. Failed the test with the paperclip and the included tester. Had a spare unit on hand from another build and the machine fires right up with that supply installed. Can't leave it in, as it's under powered for this machine. Hopefully by the time this return is processed, more will be in stock. I was looking forward to seeing what this thing could do.

Good power supply 4/13/2020 8:16:11 AM

Pros: I ordered this power supply after doing extensive research on the subject. I was somewhat skeptical about a power supply with no fan. I have only been operating my new build computer for less than a week but it appears to be working very well with no heat issues in the case. The unit came with very good information and instructions. Also, it came with a great number of cables, and all are identified on each end, for connections all sorts of equipment. The quality seems to be first rate.

Cons: I have not found anything to be a negative.

Overall Review: From what I have experienced in such a short time-frame, I would recommend this power supply.

Beautiful, powerful, quiet. 3/12/2020 8:48:16 PM

Pros: Quiet and stable. Haven't had any issues with it in the last few years. Between the psu and apc unit, my PC runs stable even when power flickers during storms.

Overall Review: Reliable so far. Quiet even when under heavy loads. Can't comment to much on cables, because I ordered custom cables when I bought this.

Outstanding! 12/7/2019 9:09:20 AM

Pros: 1: Seasonic has been cranking out great PSUs for decades. They were the OEM for some of the best PSUs released by other manufacturers, and are a fixture in the workstation space and for critical computing for a reason. They've never designed a bad PSU. Not once in their history.

I know they don't seem as romantic as an RGB "gaming" unit, but that's not the point. This is a power supply. The cleaner and more efficient it is, and the more solid, the easier a time your motherboard has sorting out the power delivery.

That does make a difference, and at the edge of performance reason, the difference is massive. This isn't a toy. This is an enterprise-grade PSU in drag, and that's why it's worth buying. You're going to have this for thirty years if you like.

2: THANK YOU for the ribbon cables. That's the way these cables need to be manufactured, and the insulation, wire gauge, and connector orientations are wonderful. A ribbon is much easier to route. Not every cable needs to be round. We've been using flat cables for over forty years for a reason.

These are expensive cables, with extremely high quality connectors and terminals.

3: On the cable front, they've included just about everything you could need for most builds, including Molex to SATA adapters and even cables with fewer connectors and of varying lengths, which is a huge savings of time and makes management much easier.

4: NOTABLE: Those airflow features on the side are functional. When the PSU fan kicks on, it's going to pull cool air in from outside the case if you like, or help vent the inside if that's how you installed it, but there's another trick...

No matter how it's oriented, once that air starts to flow, it pulls warm case air into those vents on it's way out, essentially as a free bonus. Even with a fresh air intake, it's going to help cool the case every now and again. Those things aren't there for style; they're present for FUNCTION.

5: The included accessory bundle is extensive; VERY extensive. You get literally everything you could possibly need for managing those cables. No going to the hardware store for velcro, ties, or anything of the like. It's all included, and unlike when other manufacturers put that stuff in the box, THIS time you get enough to actually do the job and have leftovers.

6: Did I mention the high quality cables? I feel it neccessary to point out that the way they folded the 24 pin cable laid it perfectly clean in three cases I tried. It just plain lined right up with absolutely no effort in three cases with three different motherboards. My word they must have spent some time deciding just where to fold it in shipping, and just how long to make it, as well as connector depth.

Don't let anyone tell you the cables seem cheap. Anyone saying that doesn't know what a quality cable feels like. Period.

7: Finish quality and fit are outstanding. Those terminals are flat and straight and high quality; far better than ANYONE else on the market. That milled aluminum Seasonic badge frenched into the back really adds a touch of "Go ahead... Make our day and stick it in a server..." visual quality. It's a heck of a statement of intended use.

I seriously dig that badging. It's subjective, but I think it makes a very nice statement and aligns with my preference for stuff that's built properly instead of built to match fads.

Metal braking, tolerances, internal components, and even powder quality are far above anything else on the market. It makes some of the most expensive PSUs on the market feel flat-out cheap. You cannot go wrong with this beast.

Cons: I guess I wish the silver grille trim was brushed or matte finished instead of chrome? That's just personal preference. It's easy to pull, and I can wrap, powder, or paint it as required; though powder really doesn't like chrome.

Whatever. That's a subjective criticism.

Overall Review: It's essentially perfect.
