Arrow Seasonic Prime 850W Review

A lot of people were impatient with Seasonic back when the Prime series of units were announced. They wondered when these units were ever going to hit the market, and why they were so content with EVGA and Super Flower getting the jump on them in the marketplace. When I reviewed the 750W model, it became apparent that Seasonic just wanted to make sure they got the job done right. Now, I have the 850W model on the load testers. Let's see if it measures up to some really lofty expectations.

I still can't believe that these ripple values are produced without even the need for caps to be put inside the cables!!

Those Seasonic guys are such showoffs. Good job on that unit. I knew it was gonna be good, but that voltage regulation is out of this world awesome.

Absolutely amazing stuff from Seasonic, Superflower must be nervous now with such a good unit like this competing.
My favorite thing of all is the tight voltage regulation,all Japanese caps,and barely no wires being used inside the PSU.

Has Seasonic mentioned if there will be lower wattage units like this 650w? 550w? or maybe even higher like 950w? 1000+w?

600W fanless.

Higher wattages will probably come later and won't use the exact same platform, this platform is only from 650W till 850W. But that's normal, platforms almost always scale 200/300W and above that a different platform is used.

Sweet mother of... That PSU was laughing at you while you tested it, Wolfy. Laughing heartily all the way through.

This is fantastic work from Seasonic. It blows everything else out of the water. And it isn't even using digital control! I shudder to think what numbers a digital Seasonic PSU would turn in...

impressive as expected. I prefer not to have ribbon style cables on premium psus, but I'd use custom sleeves anyway.

That's a really pretty PSU! I have just bought mine (850W)... But what I have noticed something weird:

As with the 750W model, you push that button in the middle if you want the fan on all the time.
On my PSU I need to push the button if I should want turn the hybrid mode on, so the exact opposite way.

My unit:

Pushed: hybrid mode on
Not pushed: hybrid mode off

Review unit:

Pushed: hybrid mode off
Not pushed: hybrid mode on

Is my unit the intended way or did I just got one of these "faulty"-Units described in the 750W thread?

I'm just a bit confused
