Anyone know about this kind of PCI-e connector?

[jonnyGURU]

Check this out....

I saw this the other day on a PSU. These are PCI-e connectors, but notice the "breakaway" black connector on the end, making the connector an 8-pin.

This IS NOT an 8-pin EPS because the 12V and ground are reversed on an 8-pin EPS12V vs. a PCI-e, but I've never seen any video card with an 8-pin PCI-e.

:confused: :confused: :confused:

looks like they were put their special for your voltage monitoring pleasure :)

I would usually look here (I could not find what you described in there, but it is a handy website I go back to quite often.):-

http://pinouts.ru/pin_Video.shtml

I checked the Matrox, FireGL and other professional GPU's, but they all use standard PCI-E connectors.

Um.. yeah.. I know.. it's linked from my main site! :D lol

But it doesn't have this 8-pin PCI-e.

[Tazz]

I googled a lot of stuff this morning and didnt get any hits on anything showing an 8 pin PIC-E.

[Effect]

Possibly something to do with PCIe 2? Who knows, maybe they're strapped on to help with 1st gen Dx10 cards =P. My head hurts now :wall:....i'm gonna put it down to an engineer with no maths skills, sorta screwed up on the "6" part of the pin design :p ....

[madmat]

I was kinda thinking that it might have something to do with the upcoming PCI-e2 as well. Seems only right since it's pushing the wattage up to 325 or so.

Hmmmm....thought it was 225?

[madmat]

I've been seeing rumours of 325W overall although it could just be more FUD.

[Bbq]

Could it be for like AGP Pro, or a certain mobo or something? I know for a fact that some manufacturers make the psu's have propriatory conectors just long enough to reach that spot on the board, so no one else can do that.

No. It's PCI-e.

[jonnyGURU]

Ok... It seems to be the new PCI-e connector for the new PCI-e 225W/300W specification.

The cards should be backwards compatible and the connectors should also be backwards compatible (like the break away pins.)

Apparently, this isn't an additional 12V and ground. It seems to be a sense and ground.

So, since this new spec is for 225W and 300W GPU's, wouldn't that mean that the most a GPU would need is 300W? And with up to 75W delivered through the slot, wouldn't that be 225W per PCI-e connector per card?

That's still a 18.75A per PCI-e connector max, 25A per card worst case scenario. Someone tell me why we need an 800W PSU for SLI?!?!?

BUSTED!!!!

[jonnyGURU]

UPDATE!

Ok...

So last week I received the Silverstone OP1000 PSU. This past Friday, I received an envelope from Silverstone with a couple adapters in it...

The OP1000 came with 8-pin PCI-e connectors similar to the ones on the Topower. Essentially 6-pin PCI-e connectors with two more pins on the end. But, as I was told, it's too easy to plug an 8-pin PCI-e into an 8-pin EPS12V connector or vise versa, so PCI SIG was working on a different standard.

Below is the 8-pin EPS on the OP1000 on the left and the 8-pin PCI-e on the right.

Here is the adapter I received:

http://jonnyguru.com/PSU/SST-OP1000/DSC00049.jpg

Below you can see the difference. On the left is the 8-pin PCI-e that is attached to the PSU and to the right is the adapter....

You can see the difference between an 8-pin EPS12V and 8-pin PCI-e below....

http://jonnyguru.com/PSU/SST-OP1000/DSC00047.jpg

http://jonnyguru.com/PSU/SST-OP1000/DSC00046.jpg

Note that the polarity is reversed. That means you can cause some serious damage if you were to plug the wrong connector into the wrong receptacle.

Silverstone tried to thwart that possibility early on by molding two of the pins into one plastic shield. If you look at the last photo, check out the PCI-e connector on the right and you'll see what I mean.

They did the same with the 8-pin PCI-e connector on the end of the adapter too, so there's no way possible it can get plugged into an 8-pin EPS either.

Unfortunately, this also means that the 8-pin connector can't be used on an "old school" 6-pin PCI-e. As you can see, I can nont plug the Silverstone's 8-pins into my load tester's PCI-e connector.

Something else to note: The extra two pins are both grounds. I was lead to believe that the extra wires would be a ground and a +12V Sense, but the wire is black and I traced it back to the PSU's PCB and found that it is in fact a ground. I believe in future PSU's with 8-pin PCI-e connectors we'll start to see an actual +12V sense lead on the connector. Currently, +12V senses aren't used in PC power supplies, so adding it would cause a delay in production. A ground will have to work in it's place for now.

[Spectre]

NIce....wait...no damn.

[Madman]

Got to love when something you just bought has some new specs and therefore different standards :p even if it is supposedly totally backward compatible I always like the idea of using the full standard the device itself calls for. Think 20 to 24 pin ATX adaptors for a 24-pin mobo.

[Bbq]

I guess that means the Olympia 1kw is up for review now? ETA?

[SKYMTL]

Ummm, so those connectsor are for the new PCI-E V2 spec???? And they will deliver up to 300W to the GPU!?!?! YIKES!!!!

[jonnyGURU]

No. They will deliver 225W to the GPU. Get it right. ;)

[Mantralord]

They should keep the connector backwards compatible with the 6-pin. I mean, if someone's dumb enough to plug a clearly labeled PCI-E cable into the EPS12V and it fries their board, then it's Darwinism at work. Why should the majority have to suffer with extra adapters and crap for the actions of a few?


Actually, if anything, more PSU plugs should be physically compatible with each other just to weed out the really dumb people. It'll be the 4th of July every day at [H]ardOCP! :fire:

[SKYMTL]

No. They will deliver 225W to the GPU. Get it right. ;)

Can you explain that please to me please. 25A is 300W, so isn't this keeping to the 300W GPU spec of PCI-E v2?

Or are you talking about the 225W for the connector plus 75W for the PCI-E slot which equals 300W??

[jonnyGURU]

75W via the slot. ;)

[skaktuss]

so, what does it mean? shoeld we start to save money for new power suplies, if we are going to get r600?

[jonnyGURU]

No. The cards come with adapters that adapt two 6-pin to one 8-pin, so if you have four 6-pins, like you would need to power 8800GTX SLI, then you're good.

Or even just two PCI-e if you're planning on just one card.

Boy are they late on the uptake......

[skaktuss]

as i understood those two extra pins are gnd. wouldn't it be easy to make a little mod? buy an 8 pin connector, solder two more gnd wires to pcb and replace 6 pin conector with 8 pin. what do you think?

[jonnyGURU]

Read the post where I show the adapters that come with the Olympus OP1000.

They are NOT PCI-e connectors with two extra pins. That's the mistake early versions of the connector made.

from the same post.
what did i get wrong?

[jonnyGURU]

from the same post.
what did i get wrong?

The shape of the connectors. Some are "D's" and some are square.

Are you able to see the photos in the post?

[skaktuss]

sorry, You misunderstood me.
i was trying to say that i could buy an 8 pin pci-e connector (the right plug with the right Ds and squares) just like i can buy 6pin pci-e connector in any pc modding shop today, or take the connector from the 6 to 8 pin adapter. then i only have to solder 2 more gnd wires, remove 6pin and add an 8 pin plug at the end of 8 wires. in such a way i avoid of adapter using.

sorry for my english! :wall:

[jonnyGURU]

Once the mod-shops like Performance-PC's have the 8-pin connector in stock, then yes. You could do that.

Or, take the adapter that comes with the video cards that requre an 8-pin, use a pin-removal tool to take off the connector, solder down a couple extra ground wires, and attach the new 8-pin to your existing PCI-e leads. Yes.

[skaktuss]

yeah, thats wat i was talking about! thanks jonny:)
i realy wouldnt like to use adapters or change my current PS, i love it too much and got it only few week ago.

I looked around at the usual suspects, svc, performance-pcs, case-mod and couldn't find the connector. Since the eight-pin connector isn't required, the 2900 xts don't seem to be shipping with them. Has anyone seen a proper 8pin pci-e connector anywhere?

[UncleJT]

Jonny, how different are the 8-pin EPS12V connectors from the 8-pin PCI-E? They looking pretty darn close and PCS has a bunch of them in stock.

[reg_pfj]

Post 13 in this thread has a picture the correct PCI-e connector. The difference is in the shape of the molded plastic surrunding the individual pins. Also, see the pdf in the first post of this thread (http://www.jonnyguru.com/forums/showthread.php?t=1220) for more details.

[UncleJT]

Ahh, yeah.. sorry, I even remember reading that. Don't mind me.

[reg_pfj]

I can't find the thread over at Anand right now, but someone there linked to performance-pcs here (http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=186&products_id=21721) for a straight 6 pin to 8 pin adapter. Not recommended. It's also not recommended because they're charging $8 for it.

More useful, it seems, would be this adapter here (http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=186&products_id=21698) because it appears to at least have the appropriate number of conductors. Unfortunately, it's for modular Enermax power supplies.

I emailed performance-pcs, and they told me they wouldn't sell the 8 pin PCI-e housing separate from the adapter in the first link. I am hesitant to spend $8 plus shipping for a stupid piece of molded plastic, so I'm just gonna rig it up until I can find a cheaper source for an empty connector.

Anyway, hopefully the links and info prove useful to someone. Or, someone has found a re-seller nice enough to peddle the housing for around $1 - roughly equivalent to what was paid for a bag of 30 of them.

On the other hand, I spent $341 on the video card. What's another $10, right? 2.9%, actually.

[RangerXLT8]

Well from what we understand the extra 2 pins provide no extra power. All I did was connect grounds to the pin. I took a modular cable from an Antec Neo and the pinout shape is the same, So I shaved off the remaining 4 pins with a Dremel and wala it plugs right into the 2 extra pins which then can be connected to the middle pins on a molex for grounding. This only has to last until my Silverstone OP650 arrives!

newbie here & need help

im using oldskoll enermax coolregiant 600w, planning to get pcie 8pin converter if available

my question, can it support single hd29ooxt 1gb later if i able to get the pcie 8pin?

[mpilchfamily]

The 8 pin PCI-e connector is part of the new PCI-e2.0 spec. This spec calls for a max amperage threw the 8 pin connector of 12.5A where as the max rated amperage for the 6 pin Connector is only 6.25A. Using an adapter for the 2900 is fine since you only realty need the extra 2 pin on the 8 pin connector to enable features of the card. But future card may have higher power needs and your PSU may not be able to support that amount of power. As you can see in the above pictured mod that is just for enabling the extra features of the card and isn't needed to power the 2900s.

Chances are that Enermax will not have the amperage available on the +12v rail(s) that your system with a future card might need. Its hard to say for sure till the cards are released.

thanks for ur reply bro, nice..

since i got extra 4pin to 6pin pcie, can i cut the 6pin & take only 2pin to be filled in the extra 8pin pcie? does it required to do soldering the 4pin?
