G80 SLI Approved List

[jonnyGURU]

The following PSU's have been load tested with parameters suitable for 8800GTX SLI configurations:


PC Power and Cooling 1KW-Quad SLI (TC1kW4E) 1000W (to be phased out.)
PC Power and Cooling 1KW-SR 1000W
Zippy PSL-6850P(G1)-PCIE4 850W (available mid to late Nov. 2006)
Topower/ePower TOP-1000 1000W (available some time in Nov. 2006)
Etasis ET-850 850W
Etasis ET-750 750W
Tagan TG1100-U96 1100W
Cooler Master Real Power Pro 850W (RS-850-EMBA)The following PSU's have been "paper certified." In other words, the power distribution and number of PCI-e connectors (4 for G80 SLI) meet the criteria, but they have yet to have been tested:

Tagan TG900-U96 900W
Silverstone Zeus ST85ZF 850WAll PSU's certified for 7950GX2 are ALSO certified for 8800GTS except for the 5.25" bay "add on" power supplies shown on the SLI Certified list. These "add on" PSU's are not supported by nVidia.

Zippy PSL-6850P 850W (available mid to late Nov. 2006)


The Zippy PSL-6850P is available for purchase now http://store.myaopen.com/psl6850p.html

Well then they're early! :D

Mid to late Nov. 2006 is what my list says. ;) That just goes to show how long the SLI certification process actually takes. :D

[davidhammock200]

Jonny, I'm proud of you!

I was going to start getting a list together, but you beat me to it!

Oh they will be certified then not available for purchase. OK nevermind...I was wondering because I bought a PSL-6850P for a server build months ago from myaopen as did slarti.

[Makalu]

That's interesting...those all have very strong 12v rails and had a 4 card quad SLI set-up in mind. Considering the 30a single card requirement these are a bit overkill maybe don't you think? I wonder if we're going to start seeing a whole lot of units with 4 PCI-E connectors now though? Also, have you seen how many connectors on a GTS card yet?

the pics i have seen of the GTS show only one PCI-E connector.

Are all of the six pins on that Zippy PCIE connectors? I thought two were, and two were those Xeon aux connectors. I never really looked into it though as my video card doesn't need a connection from the PSU.

I think Slarti's got it right. I think the "mid November" is a gaming version with four PCI-e connectors.

the pics i have seen of the GTS show only one PCI-E connector.

Really? Interesting. And a shame, because nVidia will not SLI certify for G80 if the PSU only has two PCI-e connectors.

If someone is making a G80 based card with only one PCI-e connector, it may not be with nVidia's blessing. :(

[Spectre]

Ok yeah he is...two of those six pins are aux. I got what the date means now. :o

[Makalu]

the pics i have seen of the GTS show only one PCI-E connector.

hmm so since the slot can't deliver more than 75w and the PCI-E molex is rated for 8a max...can't be more than 171w total...guess i'll know soon enough :)

[jonnyGURU]

Well, now I'm officially confused. :confused:

Attached are photos of an eVGA 8800GTS (not GTX) 640MB.

It only has ONE PCI-e connector. It also has a two four-pin Molex to 6-pin PCI-e adapter included in the package.

The reason I'm confused is that nVidia stated that G80 approved PSU's must have four PCI-e connectors and adapters can not be used in place of fixed 6-pin connectors (in other words, a PSU with two PCI-e connectors and two adapters to put PCI-e connectors on another rail via Molex connectors, similar to the way Silverstone packages the ST75ZF.)

So I can have a perfectly good PSU with only two PCI-e connectors and a pair of 8800GTS cards with one PCI-e each and still not have a G80 SLI approved PSU?!?!

Doh!

[Makalu]

In the past they've always listed them according to model number not the core so maybe that's it

[krampak]

Does it matter if it's G80 SLI approved if the PSU can hold without problems a G80 SLI with two PCIe conectors + adapters ? (as a customer I mean, not as a manufacturer).

Ah... now I cath it. You mean with GTS card, with just 2 PCIe connectors needed for SLI, sorry.

[Slartibartfast]

Bizarre. I guess to be G80 SLi approved, a psu needs to be able to handle two 8800gtx's, even if you're running 2x 8800gts? :crazy:

And I wonder what the lower-end cards will require. I know that 7600 gt's don't need a pcie power connector, so will the 8600's?

OT: do these numbering schemes bother anybody else? I think nvidia should have kept the single-digits (ie, geforce 6, 7, etc). I always am wryly amused by the fact that the geforce 8800gtx will stomp a radeon 9600xt. Oh and, ATi? Yeah, X1950XTX is not a good name for anything. They need to come up with something better.

[Hurin]

OT: do these numbering schemes bother anybody else? I think nvidia should have kept the single-digits (ie, geforce 6, 7, etc).

The numbering schemes are the same as the geforce 6 and 7 series. The 6 and 7 series saw the 6800 ultra, the 6800gt, the 7800gtX, etc. The latter parts change (gtx, gts, ultra, etc.). But there was always the 6800, 7800, 8800 scheme.

:crazy:

;)

I think there's just been some basic mis-communication from NVIDIA here. They probably just meant to say that four connectors are required for 8800gtx SLi Certification.

Here's hoping the Seasonic M12 700W appears on this unofficial list soon!

"Unofficial?" ;)

I don't think it will make the list, with "only" 56A on the 12V rail. The lowest PSU on that list has 60A on the 12V rail.

...Crazy as that sounds.

Absolutely... if it had four PCI-e.

I know, but before the 5xxx series they were single digit, like geforce 3, 4, etc, then they were called "FX" but had 5xxx numbers. I'm guessing they switched over to make it sound more impressive, and I imagine they will switch back at some point.

You have to realize the single card cert was done by a card manufacturer and the SLI cert list is done by nVidia.

And nVidia and the card manufacturers don't go out and buy all these PSU's. It's up to the manufacturer to get that product sent in.

I personally see NO REASON why either Galaxy wouldn't be G80 SLI approved.... but I don't work for nVidia. (I'd love to be the guy that certifies the PSU's though. Doesn't that sound like a cool job?)

[jonnyGURU]

Ok.. Well, it seems to me that the SLI certification for.....

G8800GTS SLI is 12V @ 55A with two PCI-e

G8800GTX SLI is 12V @ 60A with four PCI-e

Maximum power consumption of the 8800GTX is, as I had assumed earlier based on the PCI-e specification sheet I've seen, 225W per card.

This is CRAZZY! :rant:

This setup will probably blow the fuse off my home's power box. :lol:

[Skott]

I'm glad we had all our home's electrical circuitry and breakers brought up to code during the renovation two years ago. :eek:

Okay, so for those that want to run 8800GTX in SLI you need a psu with 60A total, with four 12V rails? Or just a psu that has 60A total with four PCIe connectors on it? I'm guessing the latter. I'm still trying to wrap my mind around number of rails needed for all these new cards.

Need probably won't be near as high as the recommendation is from NVIDIA as always ;)

Dailytech's test of the G8800 GTX shows that they WAYYY overestimated the power requirements for this card. With a quad core cpu and a G8800 GTX under full load, the system was only pulling 321W from the wall. With 80% efficiency factored in, a little less than 400W. That's WELL under what everyone was thinking. It's only using about 4% more power than a 1950XTX.

I don't understand why you'd need 4 PCI-E connectors, wouldn't the molex adapters work? If they do work than I'm willing to say that you can easily get by with two of these in SLI powered by something like the Corsair 520W.

You have to read what you read in context.

Like I stated this in another thread where the DailyTech article is linked...

The 8800GTX did not use much power to run the apps DailyTech ran. Yes it ran these apps better than the X1950XTX, and the power consumption it required to run these apps is minimal considering the increase in performance. But I seriously doubt that any of these apps are capable of running a G80 at it's full potential. It's probably going to take at least a year for apps to fully utilize the power of the G80 and by then, we'll all be here talking about the G90 and tri-GPU's with max power consumption of 300W per GPU. Mark my words.

The Enermax Galaxy 850W would definately work.

[Skott]

Yeah, As would the Silverstone ST85ZF

[Hurin]

Maybe I'm just misunderstanding something. . . and I don't mean to look like I'm trying to be picky (I appreciate all these reviews and information!). . . but I thought you said in this thread (http://www.jonnyguru.com/forums/showthread.php?t=262) that the M12 700W would be "enough."

So, should I interpret this as meaning that it will work but won't be getting any "official" seal of approval from NVIDIA as an 8800 SLI-ready PSU?

Thanks!

Edit: Or maybe the newer info about the 8800gtx power consumption has altered the outlook?

"Unofficial?" ;)

I don't think it will make the list, with "only" 56A on the 12V rail. The lowest PSU on that list has 60A on the 12V rail.

[Skott]

Right now I'm of the opinion the very most psu you'll need for 8800GTX in SLI is a 850w unit. Low end for a single 8800GTX is probably 600w. Thats quite a gap but I think it has more to do with the amps the psu can supply than with actual wattage. The better and higher amp units are of higher wattage anyway so to get one you'll get the other. Just my personal opinion so far. Dunno if its correct thinking or not though.

[jonnyGURU]

(I was confused myself... or drunk... when I originally replied to this last night, so to prevent any further confusion, I deleted a response and I'm editing my post to answer this corerectly and once and for all.)

I did say it would be "enough." But with only 56A on the 12V rail, it will not certify. Which is ironic since it actually has four PCI-e connectors on it.

It will certify for 8800GTS, since the requirement for that seems to be only 55A. But a GTS also doesn't need two PCI-e connectors per card.

How's that?

Personally, I would have no hesitation using an M12 with 8800GTX SLI. It's only 4A off from certification.

[Darthane]

Hrmm, would a pair of Tt Purepower express 250s be able to run an sli setup? http://www.thermaltake.com/product/Power/PurePower/w0099/w0099.asp

Of course the passthroughs for the atx would have to go (now wheres that soldering iron and heatshrink).

[Hutch]

Just to bring to everyone's attention, Coolaler (the master of overclocking) was able to run overclocked 8800GTX's in SLI on a 4.0ghz quad core with just a 520W PSU.

He also ran single card with a pretty high overclock and had measured 308W peak for the whole system with 3dmark06 running.

For the SLI setup, he used 2 molex adapters I believe and they worked fine.

http://www.xtremesystems.org/forums/showthread.php?t=121980

He makes updates all through the thread.

[jonnyGURU]

Like I said with DailyTech's results; although I believe nVidia's guestimates of how much power their cards needs are a bit exaggerated, I'm fairly certain 3DMark06 isn't maxing out 8800GTX SLI. ;)

Remember what happened when 7800GTX first came out? Everybody's machines worked great with 500W and 600W PSU's... then the software caught up. ;)

I appreciate the early results. VERY impressive regardless. But I think the cards have more potential.

[Hutch]

No doubt about that. I don't believe any software out there right now has the physics effects capabilities that the 8800 carries onboard... We'll have to wait and see what will come out soon for software but I'm very excited!

[jonnyGURU]

Well.... nVidia's 8800GTX certified list went live today.....

http://www.slizone.com/object/slizone_build_psu.html#certified_powersupplies

And it looks like my list was spot on other than one Cooler Master PSU (which I have added.)

There are still two units hanging in limbo waiting for certification. I'll be sure to report back once it gets added (or axed) from the list.

What surprises me about the 750W making the list is that it only has two PCI-e connectors. I was under the impression that PCI-e connectors had to be native and that adapters can't be used to accomplish the four PCI-e requirement. :confused:

[Flanno]

Do you think the Seasonic M12 700w with it's large 12v rail will handle 2xG80's and a Quad Core ? Assuming a single hard drive, optical, soundcard and 2/3 1200rpm 120mm fans. Everything on air.

This keeps getting asked. :D

Yes. I still think the M12 700W would do 8800GTX SLI, even with quad core.

I think nVidia's SLI requirements for G80 are a bit inflated. Perhaps "worst case scenario."

[Flanno]

Sorry...I didn't see that question.

Thanks. I bought a Ttake purepower 250w psu to stick in a drive bay and supplement the Seasonic but the thing turned out to be DOA. So hoping the 700w will do the job now when I get my GTX's. We are paying up to $950 in the UK/Ireland for these you know :eek:

[jonnyGURU]

Why did you buy the additional 250W?

I would've just tried the 700W right off the bat. If you end up needing mpre, you'll know. Cross that bridge when you get to it.

Return the Thermaltkae for a refund.

[Flanno]

Cause it was something like 29 euro in PCWorld and was the last one there. Thought it might come in handy after all the scare mongering over the G80 power requirements :) This was about 4 weeks ago. Got my refund since.

Exactly, it means you can get by with a 750w unit. It also will dpend on system components too. If you got alot of drives and stuff then probably wise to get a good 850w unit. Its nice to know though that a simple system can get by on less.

Well, I (the guy who asked a while back) will know for sure Monday. I think it'll be fine. Though, this (http://www.pcper.com/article.php?aid=320&type=expert&pid=21) makes me slightly nervous since I'll be installing this motherboard too along with the two 8800GTXes. . .

Well, the 680i chipset is definitely a power hog -- it takes up about 30 more watts of power at the idle state than the 965 or 975X chipsets from Intel. And when at a full load, the board uses over 10 watts additional power, indiciating that the motherboard chipset is indeed drawing significantly more power than the competition.

But I'm just a worry-wart. I doubt ten watts at load is going to make-or-break this thing.

As always, Jonnyguru.com has allowed me to make a much better PSU purchasing decision.

looks like they updated their description too, now "Quad 6-pin PCI-E". Excellent news though, the ST75ZF only runs about $180. No need to rush out and buy a $500 psu.

The Zippy PSL-6850P is available for purchase now http://store.myaopen.com/psl6850p.html


Zippy PSL-6850P(G1)-PCIE4 850W (available mid to late Nov. 2006)

All PSU's certified for 7950GX2 are ALSO certified for 8800GTS except for the 5.25" bay "add on" power supplies shown on the SLI Certified list. These "add on" PSU's are not supported by nVidia.

I know this was posted last week, but it needs some updating anyways.

Spectre posted the server edition PSL-6850P, which does not feature 4 PCIe cables. The G1 version is for gaming, which DOES have the quad PCIe, and comes in black, not silver. Though still, both are for sale.

And Jonny, nVidia has certified the Fortron BoosterX 3 for the 7950GX2, unless I misunderstood you.

Ummmm....yeah we already sorted that out that we were talking about two different units :rolleyes:

The original post said 6850P.....nothing else....which was the reason for the confusion.

You apparently misunderstood me, because we're not talking about 7950GX2's here. Just the G80's here.

That means that all PSU's that are certified for 7950GX2 are also certified for use with 8800GTS SLI EXCEPT FOR the "add on" PSU's.

That means, they're certified for the 7950GX2, but not the 8800GTS. On SLI Zone it says "not certified for Dual GeForce 8800 GTS" next to both the BoosterX 3 and the PurePower Power Express.

Personally, I don't see why you couldn't use an add on PSU for one of the cards and the base PSU for the other. In fact, I would go as far as saying you could use it with one of the 8800GTX cards.

I think they're worried about people running BOTH CARDS off of one 5.25" bay PSU, which wouldn't be enough power.

Well, I (the guy who asked a while back) will know for sure Monday. I think it'll be fine. H

How did you get on mate ? Did it work ok in SLI ?

thanks

Hi,
since this is my first post greetz to all and kudos to jonnyguru for the exellent website.:D
Is an corsair 520hx good enough only to run 2 8800gtx in sli? I have 2 psu so i thought that the 480W combined at 3 rails with 40 amps from the corsair should do the trick. The other one is feeding the rest of my hardware, it is an enermax noisetaker 485W.
Thnx
Dave

[jonnyGURU]

Theoretically, the Corsair would be enough to power the 8800GTX's in SLI, but because it's not a 12V power supply, I strongly recommend AGAINST running the PSU with zero load on the 3.3V, 5V, etc.

If you have a case that accomodates two power supplies, I suggest running one PSU to the board (24-pin and 4/8-pin) and the other to everything else (GPU's, drives, fans, etc.)

Just a warm-up (http://www.crazypc.ro/forum/showpost.php?p=80926&postcount=1) from our best OC-er. :)
Kentsfield Q6700, 2x8800GTX & 680i SLI powered by Tagan U25 700.
It's in Romanian but are some pictures. If it's needed I'll try to translate.
Now I'm waiting the real stuff from this guy: LN2 :D

Apparently, it worked okay. But I didn't get to test very much since it turns out that both my 8800GTXes (BFG) somehow slipped past the recall (bought at newegg on launch day). So, they're now on a UPS truck right now on the way back to BFG.

Looks like PCP&C has decided to make their Silencer 750 fully 8800gtx SLi compliant.

Silencer 750 Quad (http://www.pcpower.com/products/viewproduct.php?show=S75Q)

Still 60a on the 12v rail. So, it should meet 8800gtx SLi requirements for certification.

Sorry if this has been pointed out already. Looked around a bit but didn't see it. I'll be interested to see how quickly they can get this one SLi certified. . . or if they'll even bother.

Haven't seen it for sale anywhere yet. But it's $219 from PCP&C themselves. That's a good price considering the Seasonic M12 700W is around $210.

[Hurin]

Related to my post immediately above. . . the PCP&C Silencer 750 Quad is now officially SLi Certified for 8800gtx. :D

[Flanno]

Interesting. I see they guarantee the 750w continuous up to 40 degrees though.

Hurin - did you get your G80's back yet and how is the Seasonic handling them ?

I did finally get my G80s back after about a month all-told. But, in the meantime, I had swapped out my Seasonic M12 700W for a PCP&C (just always liked that brand). So, I wasn't able to test the Seasonic with *good* G80s and the power supply is now in my brother's computer. But, I must say that the power supply definitely didn't seem to be the cause of my problems with my two *bad* cards.

Hmmm, I hadn't noticed that change from 50c to 40c for the rating on the PCP&C. That's a bit odd. I haven't had any problems with mine, but that sure doesn't make me thrilled! :)

Also noticed that the price is now only $199.

I don't remember the old Silencers being rated at 50c. As far as I know only the Win-Tact Turbo-Cools have been rated at 50c.

I saw this post last night, but was on the verge of passing out, so thanks Spectre:p
