Performance (40% of the final score) - how about we get some scoring done now? No, this isn't the best performing power supply I've seen from Seasonic, but it's still not bad at all. Instead of being one of the best the world's ever seen, like the KM3 based units, this unit is merely just really, really good. Efficiency was a pass both times for Bronze - no issues there. Ripple control was outstanding, no problem there. About the only thing I can see to deduct would be a half point for the voltage regulation being only very good as opposed to excellent. That's all. This category gets a very strong 9.5.

Functionality (20% of the final score) - only fully modular units get no deductions here, and this is one of those kinds of units, so we're starting out pretty good. I can't, in fact, find too many reasons to complain. Sure, I could use a little more length on one of the SATA chains, and the manual's almost useless, but those are a couple of minor things. I'll remove a half point for each of them. But, I'll stop there. This unit's worth a 9 here I think.

Value (20% of the final score) - MSRP for this unit is $119.99. At Newegg, you have the Corsair TX850M competing at ten bucks cheaper, and there's the XFX Pro 850W for the same price. But you know what? Neither of those are fully modular. I'm going to go ahead and therefore call this an excellent value. 9.

Build Quality (20% of the final score) - Seasonic is doing pretty well here lately. Top notch components, impeccable soldering, and overall fantastic build quality is what we have here today. 10.

Summary

Seasonic's new and updated M12 Evo unit is a fitting addition to their already very impressive line. It's a bargain oriented 850 watt unit that doesn't sacrifice performance and quality in order to lower the price. There's really not much else to say at this point, except go buy one.

The Good:

outstanding ripple suppression
very good voltage stability
fully modular
affordable

The Bad:

could use one longer SATA chain... full tower cases may be a problem

The Mediocre:

user guide doesn't say much about the unit

Dont know anything about price yet

But i think this will be one of the cheapest fully modular units you can buy

Dont let the 80 plus bronze rating fool you despite that its a pretty good series

i can't seem to find a difference between this model and the previous one except for this one is fully modular, the last version was semi modular been debating if i should downgrade my psu to an m12ii that i have around because my rig currently doesn't even break 650w fully loaded .... and i kind of feel it's such a waste

might find another use for that 1250w PSU in another non gaming rig

While the M12II Bronze Evo Edition is not bad you can find better

Is it because its fully modular you want it?

Ripple on the old M12II was around 25mv on the new one its around 20mv

Voltage regulation is also a tiny bit better

From internals pics it looks like the 520/620 M12II EVO are the same as the old M12II low-wattage (as in, the same modular version of the S12II Bronze design we see from Seasonic and rebadged by PC Power & Cooling lower-wattage Silencer Mk III, lower-wattage Antec High Current Gamer, XFX whatever-they're-called-these-days, etc.). That's a solid group-regulated design that's a classic these days. It's kind of old but still is solid enough, nothing special.

650/750/850 M12II EVO look the same as the old M12II higher-wattage. These are units that in modular and non-modular configurations were used by Corsair TX V2, NZXT Hale82 M, XFX whatever-they're-called-these-days, etc.

Maybe the designs were tweaked a little bit and improved, but the overall topology sure looks like the old models. Small performance differences can easily be explained by just sample-to-sample variance. Think of the EVO as just having fully modular cables. It's not a huge revision.

The XFX XTR would make more sense for you then the Evo would

My SS G Series 550W bit the dust yesterday, just shut down in crysis 3, does not want to power up (just produces very silent click), didn't blew up or sparked/ smoked.

So today I got myself SS M12 II 850W EVO for a very nice price, brand new from a local IT store.

Damn this 850W EVO is LOUD.

My PC in Crysis 3 pulls 440W ftw, that/s ~ 370W from PSU itself, fan ramps up very quickly and hits very high rpm, I would say max, because if it spinned up any mor my PC would take off from the floor

It's a shame because it's very decent unit ,fully modular, high capacity and with nice voltage regulation, also comes with a very affordable price, too bad they messed up with fan / fan profile combo.

Also this fan noise issue is pretty much common on the net, dunno how Jhonny and kitguru managed to produce silent operation with this screamer.

CHEERS..

The Seasonic M12II units are very well known for being loud if you asked before you bought it i could have told you that.

I knew that but I thought these newer S12 II / M12 II units are not so loud, and reviews also stated that this unit was not so loud.

Well you get what you pay, just it's a shame for this unit as it's so well rounded and priced very nice for it's capacity/quality.

I thought it would be more silent than my previous G550 but fortunately it's not.

CHEERS..

Yeah but I was expecting that Seasonic addressed the fan noise issue in this M12 II refresh, obviously they did not.

Dunno how highly respected reviews like jonnyguru stated that this unit was not so loud, maybe they got a cherry picked units from Seasonic.

I replaced my M12II 750W Evo a few months ago for the same reason. Here is the topic:
http://www.overclock.net/t/1491830/very-loud-seasonic-m12ii-evo-750w-fan-under-load-is-this-normal

I got a CoolerMaster VS 750W instead. Same price, Gold and completely silent.

I'm not sure what the hell Seasonic was thinking putting a leafblower fan in there...and it's not exactly cheap for a Bronze unit. Seeing how many people complained about these being loud while none of the reviewers did makes you think if Seasonic sent them 'special' units.

So did turning PSU upside down really helped with fan noise, I'm open for all suggestions?

It did help a bit...I posted a couple of videos for comparison. However even after turning the fan upside down it was still the loudest thing in my PC. So basically, it went from obnoxiously loud to just loud. I guess it depends on what case you have and how much sound it'll block from inside....worth a try I guess but I'd save myself the headache and replace it with a different PSU.

WOW man thanx a lot, this made a world difference!!! +rep

There's no more air turbulence sound created by double set of grills of my HAF 932 case underneath PSU fan , so there's no more that annoying hair dryer sound!!!!

Here's how I positioned my PSU, now it takes air from the case itself but w/o any obsticles that woud get in way of PSU fan and create turbulence sound.

If I put my palm near PSU fan grill it would produce turbulence and that horrible sound that was driving me crayzy.

Now I can live with this unit as it's by far the loudest component in my PC!!!

I guess now I will sell SeaSonic G Series 750W tha I will receiveas a replacement for my dead G550 unit.

Also now it's much more easy to vacuum clean my PSU with fan facing up .
