Seasonic M12

Image

- It'll be available in 500, 600 and 700W models
- It is the same base model as the S12 but it's modular AND has an extra 60mm fan at the back (thermo-regulated; only starts spinning at a given internal temperature)

Seasonic S12 update

Image

New "Energy +" models: 550 and 650W (80Plus certified).

The Seasonic M12 is expected to come out in June and the Energy + S12 in May.

---

There's also the new V8 (300W) which is quite similar to the SS-300SFD. It has a 80mm fan thermo-regulated by the same controller as in the S12. It'll have +80% efficiency although not being labelled as 80Plus certified.

It seems to me that Seasonic have been sitting on their laurels for a couple of years now, we haven't seen a totally new PSU from them (ie new PCB etc) since the S12 came out; I would like to see them come out with a hyper-efficient PSU (89% or thereabouts for 220V markets) to really shake up the competition in the uber-silent PSU arena.

1) What do you think would be more quietet: S12-650 Energy+ or M12-700?

I'm definitely upgrading to one of those if either is more silent or more effecient than my current S12-600.

2) Do you guys think an S12-650 Energy+ would be enough for X1900XTX Cross-Fire + FX-60 + rest of super-high-end rig?

Does anyone have news on what the Energy S12 models are being released? It's obviously about to pass May so the original date doesn't apply now. Also I noticed the New Seasonic website shows September for the M12 model now.

Yes. If an S12-600 can cope with XTX crossfire in a high end rig, an S12-650 will be fine, even with an FX-62.

I wonder why they added the extra fan for the M12.

We(www.hardware-test.dk) talked with seasonic at CeBIT, and they told us that the little fan had a kind of anti-shaking-funktion. Most like some engines which can eleminate vibration with a anti-cylinder. If it should move air a 80mm fan would be a better choice.

I hope you can understand my danish-english. :lol:

I can't wait for the reviews of the M12 500W and the S12 550W Energy + so I can decide what to replace my S12 430W with.

Of course it'd help to know the thermal values for tri and quad core K8L processors so I'd have some concept of total power draw for a high end AM2 system when dual core becomes entry level and quad core is not terribly uncommon.

The M12's small fan may become a problem, if it's not spinning all the time, because hot air would flow back into the case through it.
And it's much larger than the vents that were already blamed on the S12-430 series.

Well it is thermally controlled. Maybe it will be running at any point when the heat going back into the case would be a noticable issue.

Wow.

I'm really shocked they threw a 60mm in the back. I'm sure its fan controller is very aggressive at keeping it off and the voltage down when it is on, but we all know we will probably end up with an inferior Seasonic from a noise point of view.

There must be a better way to exhaust the hot air buildup in that region of the PSU. Internal Ducting? Heatsinks? Or, at the very least, an 80mm fan? I know a lot of people are not happy about passive vents in that area on the S12, but I'll take those over a 60mm fan any day of the week!

If the 60mm fan only comes on at 200w DC or higher I'll have so much sound going in the programs I'm using I won't notice.

The key is making sure that fan is off below 200w DC so that it isn't bothering me when I'm browsing the web or leaving the PC idle.

I honestly don't know if 200w is the magic number I just know I got a super cheap UPS and by comparing its specs to my run time the quietest online game I play runs one of my systems around 130w AC if I figured right...

That won't be before 2008 at the earliest, so there's no rush. I doubt a quadcore K8L will use much more than current top-end procs, AMD seems to cut power consumption with every new generation of CPU's, also they will be going to 65nm etc.

How fast does a 60mm fan have to go to prevent air from going into the case again? 100rpm maby?
Off might not be so good as someone pointed out already but having it running extremly slow will not be measurable. Atleast I think so :-)

Depends on the negative pressure inside the PSU casing. I agree, it probably doesn't have to be much, but it would probably be a good idea for someone to start looking for quiet 60mm fans in the event a fan swap is needed.

Nexus doesn't make a silent 60mm, do they? (j/k of course, I know they don't)

Don't know if this has already been discussed in the forum but Seasonic is (would be ?) working on a fanless power supply, but without any launching date known.

I see Google says M12 will not be 80+

for that matter...can any modular PSU ever be 80+..or will the impedence of the modular system always degrade the current?

Looks like the 60mm in the Seasonic M12 is an Adda model, bodes well for noise.

Quote:
Enfin terminons par une très bonne nouvelle : Seasonic travaille sur une alimentation fanless mais aucune date de sortie n'a été avancée. Connaissant le sérieux de la marque, on peut se mettre à espérer à une alimentation de rêve combinant excellent rendement et silence complet...

At the end we finish up with a very good new thing: Seasonic brings up a fanless power supply with no release date except late summer. Knowing the series of the brand, we can start to wait for a dreamy power supply combining excellent efficiency and complete silence...

(I'm only a fr-1, go easy on me...)

Nope. Just the new 550W & 650W S12 Energy + (as mentioned on the OP).

Very close :)

"Let's finish off with some very good news: Seasonic is working on a fanless PSU, with no tentative release date yet. Considering the company's reputation, we're crossing our fingers for the power supply of our dreams, combining excellent efficiency(output?) and total silence"

July going to be a busy month ... Conroe, price cuts and S12 650 :)

"The production of M12 and the S12 news was confirmed to us for the beginning of July with a quasi immediate availability of S12 and an availability of M12 for September." (from translated, linked article)

Dual core AMD processors will be under $200 in just about a month. July 24th 2006 is when the price drop for X2 is supposed to hit.

Quad core AMD processors are supposed to be out in early 2007 and by Summer 2007 the EOL (End of Life) models of the early X2 lines will be entry level if my guess is right.

Both INTC and AMD will push dual core and higher for back to school 2006 and Christmas 2006. By Spring 2007 you won't think of dual core as anything that remarkable it will be so over advertised...

Tak a look at the X2 prices from late next month and guess how cheap the EOL 939 parts will get this fall.

Code:
       939   AM2
-------------------------------
3800   ???   169
4000   ---   ---
4200   ???   240
4400   ???   ---
4600   ???   301
4800   ???   ---
5000   ---   403


We can debate the concepts of "entry level" and "uncommon" but the point stands that the parts are coming and I'd like to know the next Power supply I buy could hold its own with a dual socket AM2 quad core (8 cores) setup and still be quiet and effecient at 200w DC load.

In case you didn't know (any many don't yet). The Quad core chips will power down or change clock rate independently. If you are truly idling a quad core can become a single core temporarily or use 1 core at full power with 1, 2 or 3, cores at 33% clock speed and/or off and/or full speed.

As far as I know. Main topic for Seasonic engineers at this moment is to settle down incompatibility problems with different types of motherboards. Maybe after that, and after nVidia changes GPU power socket to 8-pin they will present something new ;)

Yes, but this will be a server processor (Deerhound), not a desktop chip. Also it looks now like Deerhound will not arrive until late Q2 '07.

Quadcore on desktop will not arrive until 2008 at the earliest:

http://www.dailytech.com/article.aspx?newsid=2388

Quote:
AMD will introduce no less than four quad-core families over the next two years, with the first being Deerhound. Deerhound, we are told, will be a Socket F server processor expected to ship late next year on the K8 -- not K8L -- architecture. Deerhound did not appear to support FB-DIMM.

In early 2008, AMD's corporate roadmap claims a quad core desktop CPU will make an appearance, dubbed Greyhound.


http://dailytech.com/article.aspx?newsid=2531

Quote:
Quad-core Revision G Opterons (Deerhound) are not anticipated for at least another year. (from article dated 25-05-06)


Also, as you point out these processors will have very sophisticated power efficiency features, so I am really not convinced that a new power supply will be necessary.

So you think quad core single socket won't be common enough for me to be concerned about any time soon. How about dual core dual socket AKA 4x4? Those parts are expected this year.

You are using the tactic of arguing what is known to put down me asking about what isn't known. It isn't helpful.

I already spend 40-100 hours each week reading about and dealing with computers and could easily take your side of the argument and run with it. I don't need to argue with myself.

I know that change is coming and no matter how silly you think it is, I build systems using a hand me down process. The choice I make for each purchase affects the choice for each build in my chain for years to come. I'll occasionally have to orphan some spare parts along the way but on the whole my number of usable systems improves over time.
