Seasonic S12 spotted at Xtremesystems

Just noticed someone benching with a new Seasonic S12 430w here - http://www.xtremesystems.org/forums/sho ... hp?t=49332

Hopefully this means we'll see an SPCR review coming soon

There seems to be a review out. When are these due to hit stores? Until SPCR reviews this, I think I'm going to keep my Seasonic Super Silencer 460 A3.

Looks like they're using a Yate Loon D12SM-12 rated at 70.5 cfm with 33 dB.

I've been looking into getting one of these for my new Nforce4 board.

Can't wait till they hit the stores!

Another review here - http://www.3dvelocity.com/reviews/seasonics12/s12.htm

Looks not bad, notice theres no pci-e connectors tho, also shame theres no 500W+ version too.

DocSilly · Post by **DocSilly** » Tue Jan 04, 2005 11:56 am

Actually there will be a 500W and a 600W Version of the S12 with > "Additional 6Pin Connector for VGA card(500W & 600W)" http://www.seasonic.com/new/new.jsp

I like several physical aspects of this PSU as reported in 3dvelocity : fan mounted on grommets, fairly open interior for (hopefully) reduction in turbulence noise, no bling. Personally I rather like the matt black finish.

Looking forward to a SPCR review.

Hmm... I hope that Yate loon isnt going to be too noisy. I would have jumped for job if they used the low speed version of that fan. But, I await a SPCR review...:p

Damn!

I've just bought a Seasonic Tornado 400W...

As have I (about two weeks ago), with full knowledge the S12 was coming out. We both have great power supplies, rest easy.

Hardcore

Next gripe is the 600W version should have 2 PCI-E connectors to be SLI ready

DocSilly · Post by **DocSilly** » Thu Jan 06, 2005 9:46 am

Just use a 2xMolex > 6 pin PCIe connector for the second card

The 500W should be enough to power even the beefiest overclocked FX55 + SLI 6800U loaded beast.

Suppose that'd suffice too, but would be nice to have 2 x proper PCI-E connectors just to help keep tidy (and I imagine any SLI system would already be cramped/messy as it is)

One very important point about PCI-e video power requirements:

There was some confusion between Intel & nVidia about how much current was to be available for this. Initially, Intel specified 75W. nVidia wanted 150W available. So some time later, Intel & nVidia agreed, and 150W is the correct max power draw that should be available on the PCI-e graphics line.

Many PSU makers went with the original 75W requirement. You have to check on the fine print on "PCI-e ready" advertised PSUs to find out whether it's 75W or 150W. If 75W, newer generations of power hungry PCI-e video cards will not be supported.

The Seasonic S12 500/600 both provide 150W on their PCI-e video output line. It's not clear how many others do; most seem to be at 75W.

Mike do you have any insider info on when this will be retail ready or rough costs?

Thanks for pointing out the info on the PCI-E power requirements. I need to be sure to have a decent PCI-E ready PSU since I plan to go 6600GT with my Nforce4 setup, and they draw their current directly from the PCI-E slot. At least I haven't seen any that require additional power yet....

AFAIK, the S12 series are available in the US right now, and cost will not be any higher than Super Tornado (for similar power rating).

It looks like a nice unit but according to a http://www.3dvelocity.com/reviews/seasonics12/s12-4.htm article it's 12v rail is really wimpy for it's wattage. That makes it a bit questionable for nForce users since both our GPU and CPU run off of the 12v rail.

ilh · Post by **ilh** » Sat Jan 08, 2005 3:32 pm

29A total on +12V is wimpy for a 430W PSU?

Sorry, PorBleemo I can't find that statement in the article you cite! They say, on the contrary:

3dvelocity wrote:The S12 may not match the Tagan for its ability to boot with 25 Amps of load applied, but by returning an incredible 11.70V under that load it simply outperforms every unit we've tested to date.

and later:

3dvelocity wrote:If you want a well built, top performing power supply that has one of the most bomb-proof set of voltage rails in the business I reckon this could be the one

Or are you referring to the fact that the S12 was not able to boot, with 250W of load on the 12V rail in addition to an Athlon64 3400+ and a Radeon X800 Pro connected prior to hitting the power button (adding the load after startup was no problem)?

Tephras · Post by **Tephras** » Sat Jan 08, 2005 5:09 pm

It's an overstatement to say the PSU is wimpy just beacause it cannot boot up with 5 halogen spots connected, the PSU is supposed to provide power to the computers components not to provide power to a hotbed. That test might be god to find out the limit of a PSU but it can't be looked upon as a way to simulate the power drawn by a "normal" computer system.
Note that they make a reservation regarding their test method:

3DVelocity wrote:Keep in mind though that even an additional 150 Watts is quite extreme when used in addition to a normal motherboard connection and while also running a Radeon X800 Pro as I was.

Live · Post by **Live** » Sun Jan 09, 2005 4:17 am

I guess the only time you draw that kind of power is if you are using a peltier. But that should be run of a seperate PSU anyways.

DocSilly · Post by **DocSilly** » Sun Jan 09, 2005 4:50 am

And a system doesn't run 100% load during bootup ... CPU and videocard will only run full load when the system is already running (encoding, playing games etc.)

JanW · Post by **JanW** » Sun Jan 09, 2005 6:02 am

My point exactly. Suppose you have harddrives that draw an extremely high current of 3A during spinup (Spinpoint series use 1.9A IIRC), and suppose all of that is used on the +12V rail (I'm not sure it is), you can still put at least five, probably six (216W), of these (or 8-9 SpinPoints!!!) and be fine. Who would run a larger disk array without a controller allowing staggered spinup? What else could possibly use such a current?

EDIT: removed comment about peltier since I don't know anything about them.

(first post, long time lurker)

Has anyone actually seen an S12 available anywhere? I've been looking around the web and I couldn't find it.

I'll second that......if any knows of a vendor(s) who has stock on these, please post it.

I have been looking for 2 days. I also sent an email to seasonic (I doubt tey will reply) I will post if i find a vendor

BTW that's some crazy overclocking. Going from 1800 to 2800 MHz, that's a 55% overclock!!

Stock cooler I recon as he does it again with the new epox board here - http://www.xtremesystems.org/forums/sho ... hp?t=49475

Nice looking board that new Epox one tho, only issue is can see is the placement of the atx connectors, but thats the way Epox have always had them

2.7 GHz with stock fan and standard voltage... Ebbeh.
