Are you running cards crammed together in your mining rig and need extra airflow? Or do you simply wanting to circumvent space issues with a small case? Purchase a PCIe slot Extender Cable, PSU Adapter Plug, GPU Dummy Plug, and other great items to allow for increased airflow, room, and mining efficiency.


These products are offered for Bitcoins & Litecoins! View the web store at www.Cablesaurus.com to purchase an item with Bitcoinsm Litecoins, Dwolla, or Paypal, If you have any questions e-mail sales@cablesaurus.com or PM me!

You may want to offer a modified version of the x1 extenders (cut open the back end) also. That is worth half a BTC or so to me.

I don't have any Molex connectors available to harvest at this time or proper modification equipment, but I'll definitely look into modifications at some point in the future.

I have updated the BTC prices to reflect BTC value increases!

I would be interested in donating or trading for a means by which I could track & modify this sell-post automatically as the market changes. If you think you might be able to accommodate, please contact me.

Hmmm, just had a deflationary thought moment ... would really like a few of these for testing but now they have dropped in price ... do I wait until BTC goes up more or do I buy now because they could earn me more .... ??

Weird feeling, well not that weird, I've been sitting on gold for 15 years while my house crumbles down around me lol.

I would be amused to know whether eBay cuts your listing short simply for including the word "Bitcoin", regardless of the fact that you're not mentioning it to solicit a non-PayPal payment.

And if not now, in the future.

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable.  I never believe them.  If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins.  I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion.  Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice.  Don't keep coins online. Use paper or hardware wallets instead.

I'm having trouble picturing the use of this card in my head - it looks too weak to hold the heavy card up - or the card would flop over on its side and block it's own airflow. Do you have a picture of it in use?

The easiest method would be to obtain some cheap L-Brackets with which you can affix to an open area of the case, this would allow proper support rigging.

Looking at the "PCIe 1x Slot Modified Riser Extender Cable".
I assume that the "modified" part is that you cut open one end of it, so 16x cards can be inserted into the 1x riser? correct?

These are for anyone running a 5970 or a 6990 Card via an extender cable. It has been shown that enough power is being drawn through the PCIe slot to cause physical damage to a cable in a short period of time with a highpower card. This modification allows bypassing power around the PCIe bus.

What lengths do you have the PCIe x1 modified cables in?

These guys have up to 50cm but at some point the comms link will be affected I suspect.

http://www.ameri-rack.com/ARC1-PESX1B-Cx_m.html

Also are your ribbon cables shielded (EMI shielding) like these ones?

I'm up for one if length is longer than 10cm. If I can get 30cm would be great.

Hello folks,

Cable length is about 19cm or 7.5''. The cables are not shielded (at this time) though it is not an issue from what I've experienced as long as no devices touch the cables and the cables themselves don't touch each other. trentbz has no issues with his pictures posted above from what I've been told, if I understand correctly.

I should have a chance to hopefully get some decent pictures together tomorrow.

Thanks for the questions & input!

Yep

Will the graphic card connected to the x16 get more mhash/s than the other one connected to x1 if both of them are the same model?
Both slots will deliver the same performance for mining.

PCI-Express PCIe 1x Riser Card Flexible Extender Cable
PCIe 1x to 16x Adapter Modified Riser Extender Cable
PCIe 1x to 16x Adapter Modified Riser Extender Cable w/ Molex Connector

What is the different between the above three? Do i need it for 5870 cards, if i want to put 8* 5870 cards which has 8 slots(4 x16 or x8  & 4 x1 ) or any combination, but has 8 pcie slots.

I understand 1x cable , just gives lengthy cable so that card can be placed at a distance.
You attached molex connector, so it won't try to draw power from pcie slot.
But what is 1x to 16X modified extender cable? I don't understand & why this type of cable needed. Do it may need for 5870?

How many days approximately it will take to reach to Tamilnadu, India after i paid & you received money.

The slot adapter cable is to fit a larger card. So, for example, if you have a 5870 to connect, but only a 1x slot free, you could use this adapted cable with the side cut off the socket to fit a larger card.

This will suit for any card and you would use the Molex modified one for mainly 5970's or 6990 cards.

Shipping time will depend on the chosen method of shipping, however shipping is still available on International packages via First Class, Priority, or Express.

I got my order of extenders today.  However, I have a question/concern.  I'm not terribly knowledgeable about the PCIe pin package, so forgive me... but only the +12v connection on the PCIe bus is connected to these via the MOLEX.  That would seem to me it's allowing the ground to go through the bus on the motherboard.

If I were to power one of my cards with a PSU that is NOT powering the motherboard, it's going to create a ground differential that may burn out the card, the motherboard or both.  Can someone explain why this is not an issue?  Or are the cards taking their 75v from the PCIe bus not grounded through the bus?  I'm thinking they have to be, since you can put cards in a machine that do not have external power requirements and supply solely off of the bus. 

If you're searching these lines for a point, you've probably missed it.  There was never anything there in the first place.

This may be an issue although I cannot definitively confirm as I haven't modified PCIe extenders to peel off the 12V to test yet....will do so in coming days.

However I did work on multiple PSU arrangements yesterday where one is powering board/peripherals and a GPU or two and a secondary ATX PSU powers additional GPUs. This arrangement works but grounds must be connected between PSUs. It may be something specific to my particular PSUs but I found it was not enough to light up a GPU by just making PSU #2 hot with PSON. I had to connect PSON + GND to PSU #1 and I was then able to light up additional GPUs.

I also wonder about how a GPU will light up if PCIe +12 but not GND is supplied from a secondary PSU/source. I believe forum user mrb has experience in this area, maybe he can provide some insight if he runs across this thread.

Ground is going through the PCIe bus. Pins A2+A3;B1+B2+B3 are the 12v pins rewired to the Molex. Regarding GPU detection using these cables on a 5970 or 6990 would detect without further wiring modifications.

Trentbz/Inaba, http://blog.zorinaq.com/?e=44 Per the reference posted in this blog and confirmed test current drops from a combined 14A to < 1A. Preventing cable wear from extended use. Let me know if any questions.

Thanks for the link, but I don't see where it's saying he was using two power supplies with independent ground potential.  From the way the blog reads, he's connecting the +12v to the same PSU that is supplying power to the motherboard, making the ground the same regardless of the +12v source.

If my +12v source is coming from a different PSU than is grounding the motherboard, the potential will be different and that's where the bad things can start.  I completely agree that there would be no problem supplying +12v from a molex on the same PSU that's grounding the motherboard.

I believe mrb is using dual PSUs as listed at http://blog.zorinaq.com/?e=42.

Quote
First PSU to power the four 8-pin connectors:
4 * 11.4 (8-pin) = 45.6 Amp
Second PSU to power everything else (four 6-pin connectors + four cards via PCIe slot + ATX connectors for mobo/CPU):
4 * 6.7 (6-pin) + 4 * 3.7 (slot) + ~3 (mobo/CPU) = ~45 Amp

I can't determine by his post how he has ground connected between them except that supplying the PCIe 8-pin via PSU #1 and supplying the PCIe 6-pin + PCIe slot via PSU #2 should tie them together sufficiently...not sure if this was intentional or not though.

I am not yet providing 12V to the PCIe slot via an extender but I did do dual PSUs yesterday and when I supplied PCIe 6-pin from PSU #2 to GPUs and PCIe slot/ATX/peripherals via PSU #1 I could not get GPUs to light up. As soon as I cross connected the PSUs via PSON and GND the GPUs lit up as expected.

I would suspect that you may have issues if you provide PCIe 12V and/or PCIe 6/8-pin from a secondary PSU that is NOT common ground with primary PSU. I know I did with providing PCIe 6-pin separate than PCIe slot 12V.

And fortunately, I didn't kill any GPUs during my 30 second power up. Smiley

Yes, best if used off the same PSU. Also if using multiple PSUs just make sure all your grounds are common. What crazy set-up would have two PSU's right next too each other, supplying the same equipment with 'floating' grounds? You are asking for trouble if that is your case anyway.

Whole server farms make sure that the ground is common throughout the building. If you want to have floating grounds that is your own problem I'd say. The basic idea is to bypass power around mobo to PCIe GPU card, ATX PSU connectors have reported burnouts with more than 3 5970's on same mobo.

"all your grounds are come"  what does it exactly mean?

In my house their is a ground given by inserting a 1 inch GI pipe in to earth for around 2 feet & a wire is connected to that, that wires goes to every electrical  board in my house & connect to central big connector in a 3 pin connector.
Is that you saying to have common ground?

Today, i have to run 2 systems with one pc has one 6870 & other has one 5870.
I have only one cooler master GX 550W power supply & 2 low cost PSU which comes with cabinets.
I thought of connecting the low cost psu to motherboard & give power to system.
Then short the pin of GX 550 W PSU mother board connector 20 + 4 pin (Don't know which 2 pins/connections to short), which will switch on the GX 550 W PSU.
& then connecting(only after switching off 550 W PSU & computer) PCI-e 6 pins connectors from GX 550W PSU to the cards in 2 separate pc, the 6870 & 5870.

Can it be done & is it safe to do it?
I won't run this setup for months. It is just for 3-7 days, until i get Cooler master silent pro gold 1200 W. Its in shipment & i don't want my newly bought 5870 card lying around.

Aren't the PSU's and/or motherboards floating ground by design?  I just don't know enough about the internal grounding of a computer PSU and the motherboards to speak with any authority which is why I was asking.  But I thought I remember reading somewhere that most commodity hardware on the desktop has floating grounds due to cost issues or something?

If you're searching these lines for a point, you've probably missed it.  There was never anything there in the first place.

You can go for that cable, which is hassle free. But yesterday, i have to run my 5870 card, so used the psu(220-250W) in cabinet as it is. Then took another 250 W PSU, using molex to pcie 6 pin connector, connected & powered the 5870 card.
To start PSU, i used a wire to short pin 14 & ground. Pin 14 is GREEN & ground/com is any black which is near.
Everything works fine.
You can try this simple method & for safety use cello tape to cover the wire & 20/24 pin motherboard connector, which avoids accidental pulling of wire & safe to handle.
Or you can buy that cable. I hope technopagan can buy & send for you, but the shipping cost & time will be a problem if you are far from him.

Thanks for that. I actually used the green/black wire trick many times on water cooled set ups to fill the system and remove air bubbles without booting anything up. I can use that, certainly, but I don't like the idea of someday having to power down the machine remotely (has happened) and having that PSU just running and feeding a GPU, thus I search for something more permanent. I could just hack the thing up, push some clips into the connectors and all but there's enough equipment value involved to go that extra step.

Definitely, value of hardware is important. I gave the link for temporary purpose only, which i found out yesterday to run my pc & happy that you used that before itself.
The cable you mentioned, is actually the best solution available, coz it won't need additional on/off, watching....

If you're using a PSU not grounded to the motherboard, do not utilize a cable with modification. Make sure any secondary PSU to be used would be grounded through the motherboard.

I'm not sure if grounding to the case would be sufficient, it may or may not. More input would be helpful.
I've not used 2-PSU setups on my rigs.

There will be a 48 hour delay on shipment of 1x Extenders, 1x -> 16x Adapters, and 1x Extenders w/ Molex. Waiting on additional inventory that hasn't came in yet.
Feel free to place your orders and they will be sent out in the order received, hopefully sooner than expected.

I'm preparing Cablesaurus.com with a Bitcoin shopping cart, launching tomorrow morning, which will allow Bitcoin & Paypal purchases directly from my shopping cart. Stay tuned.

I assume you could use these cable mods to run your PCI'e cards from a different PSU to your system PSU?

If you're using a PSU not grounded to the motherboard, do not utilize a cable with modification. Make sure any secondary PSU to be used would be grounded through the motherboard.

So if we are not using any modified cables, there is no need for grounding a second (or third) PSU to the motherboard? 

I have used the paperclip trick to put a second 400W PSU to power 1/2 of a 6990.  The PSU is sitting on the table and have been getting pretty good performance for the last 24hrs.  Am I missing something / doing something wrong?

If you are powering anything plugged directly into the motherboard with a second power supply, you have a potential grounding problem.  The kind of problem I've described here is not one that will blow up a card immediately and you'll instantly know there's a problem.  The grounding problem of this nature will slowly burn out components over time and/or shorten the life of the equipment.

The questions that arise then:

Is the problem is pronounced enough to worry about?  e.g. Will it shorten the life of the equipment enough that you care.
Is grounding to the case sufficient to make the ground differential acceptable?
Which (if any) pins on a modified cable need to be grounded to a common ground?

Personally, I would not try using two PSUs on anything expensive until I understood exactly what the consequences are.  It's entirely possible that you can burn out your card, motherboard, or PSU or any combination thereof.  It's also entirely possible that this fear is completely groundless (pun intended) and there's no need to worry at all. 

If you want to use two PSUs, the least you should do is make the grounds common by combining the two ground pins on the two PSUs.  I'm not sure this will solve the problem or be snake oil, though.  But at least it's something.

If you're searching these lines for a point, you've probably missed it.  There was never anything there in the first place.

Assuming the 'COMMON' or 0V pins are indeed connected to ground (which in my very limited knowledge of electronics I'd assume) then wouldn't the hack to make the slave PSU power on with the master one automagically solve this? We are connecting one PWRON and one COMMON pin across the PSUs.

So I did some more research on this... came across this, which is encouraging:




Quote
Yes, connect the "master" PSU's 20/24-pin to the motherboard and connect two jumper wires between it and the "slave" PSU. Referring to the pin-out diagram above, connect green to green and any black to any black on the two units and the slave will power on and off when the master does with the front chassis switch. The slave units are usually used for their additional 12V capacity to power graphics cards, fans, water pumps and the like but should also be used to power a couple of drives, either optical or hard, too. This will put a small load on the 5V rail and less stress on the PSU trying to deliver a 12V only load. Instead of using drives for a 5V load you can make a "dummy load" with cheap resistors. Two 10-ohm 10W ceramic resistors or a single 5-ohm 10W aluminum will put a 1A load on a 5V circuit and dissipate ~5W of heat.

Ready made dual PSU adapters are sold by Ultra and Lian Li and also come bundled with Cooler Master dual PSU capable tower cases. Performance-pcs.com selling the Ultra adapter does ship worldwide.

By using the mentioned "hack" we will be connecting one "COMMON" line along with the "PS_ON". This is ground(ed), right?

Without seeing your exact set-up, I'd say, yes, that should do it.

19cm is the maximum supported length for PCIe extension. However with a Mining Chassis you would be able to reach the cards without issue.

Those look good, but I see some issues with them that are a real deal breaker for these in quantity (which may be fine if you aren't looking to do higher quantities):

1. It's about 1" too high and looks like it could be lowered 1" without causing clearance problems.  The 1" would facilitate it being able to be put into a 1/4 cab rack in pairs.  With the current height, you can only get 1 in a 1/4 cab with 90% of the space needed for a 2nd one going to waste.
2. They don't look like they can be stacked and have no provisions for mounting in a rack from the pictures.  Ideally, being able to stack them in a rack would be awesome.
3. Is there space for 2 PSUs?
4. With #2 the hard drive placement makes stacking difficult.
5. Nice to have the option to move the cards closer together to have 5 (or 6?) cards in one machine.  I would like to run 5 cards per mobo, but 4 is nothing to sneeze at. You don't need a lot of space between cards to cool them, which brings me to the final #6
6. There doesn't appear to be any place to mount fan(s).  Regardless of it's open air design, if you put these in a rack, you absolutely need to get some airflow going from front to back.  Being able to mount a couple 120mm fans on the front blowing across the cards towards the back would be important.

Otherwise, these look pretty cool and I'll probably get at least one for my own personal use if not a couple.  If nothing else, they'll make interesting desktop cases Smiley

Absolutely none for a rack case/mining rig.  As a desktop case, I'd say somewhat important. 

I think that you could mount both an HD/set of HDs and an optical drive on the side and "inside" the case, so even if you wanted to rack it or stack it and still maintain your drives, that would be ideal.  Now that I think about it, actually would be pretty awesome to be able to stack theses even on a desk where the bottom of one will fit into the top of the other one to provide some stability. 

Just for reference, 1/4 cab is usually 10U, giving you 17.5" of vertical space.  Most cabs are 19" wide, though I hear there are 23" ones, but I've not ever used those variants. 

If you were so inclined and needed more room, you could stretch it out a bit, since there's plenty of room in a cabinet from front to back.

Received cables i ordered on 16th in 7 days to my home, India with customs clearance.
I was in fear that 27% customs has to be paid, but courier guy just gave parcel & went.

But, small mistake.
I ordered 21 nos. 1x to 16x modified extender & 2 nos. 16x to 16x extender, & i received the same only. I counted it to verify.
But, the customs dispatch deceleration note says, 15 + 2 =17 only with a value of 240+ USD.

Is this made me customs clearance easy?

I give +1 or +23 to cablesaurus for door delivered to me in one week in perfect condition.
Thanks.

Hey there Dishwara,
Actually that was just an issue with getting the label to print in Paypal with an old method, as each cable does not weigh 1oz. Paypal shipping is weird sometimes.

Hi I've briefly gone thru the thread, I know some mods are done and stuff but are the 1->16x extender adapters readily available in stores? I've been meaning to build my first rig and have been trying to skim on the MOBO and other peripherals to mining as much as possible. I don't think I can wait for ordering this to arrive.

And does using PCI -> PCIe adapters hurt the MOBO in anyway? I'm trying to get 5/6 slots total (PCIe + PCI) and get 8 GPU (2x5970 + 4x4850) on 1 rig with 2 PSU which I still have no idea how I'm going to hook them up yet.

Is this possible?

Tested it today and installed another video card on my mining rig.  The cables were shorter then expected (7 inches) but I manage to fit the card by balancing it on another card.  Works great!  Thanks.

Will test daisy chaining them later on.

Daisy chaining DOES NOT WORK.  If you get it to work at all, your system will be horribly unstable.  This is unfortunate, because as far as I can tell, it's impossible to get longer cables than the ones Cablesaurus sells for a reasonable price.

That said, I've bought several cables from Cablesaurus, and they work just fine, and service has been great.  There was a small miscommunication in which I was sent a x1->x16 w/ molex cable instead of a full x16 w/ molex cable.  He sent out the proper cable immediately at no charge, and I used to x1->x16 in the meantime.

By the way Cablesaurus, I picked up some envelopes today, so I'll send the x1->x16 cable back to you as soon as I get a chance to go to the post office.

19cm is about the max you can go with PCIe. THats why Cablesaurus doesnt make them any longer, and its also why you cant daisy chain them. IF you wanted a longer cable you would have to HEAVILY shield each of the many wires of the extender.  PCIe was never meant to be used over long distances so there is almost no noise filtering in the bus, it just wasn't designed for that. 

If the extenders I ordered from the chinese seller on ebay doesnt show up by Tuesday, I will order them from Cablesaurus.

I believe it's the same cable, but Cablesaurus ships from the US, while that Ebay seller ships from China.  With Cablesaurus you wait 2 or 3 days (assuming you're also in the US), with the other seller you wait 2 or 3 weeks.  If you're depending on having those cables to add more mining capacity, getting them quickly is of utmost importance.

Hey guys I just got my 1x->16x extender and I can't get my comp to pick up the 3rd card. I've tried with and without dummy plug, still no go. Can anyone post up a picture of using a 1x slot with the extender to the vid card? My buddy tried everything even messing with bios and nothing seem to get the video card detected.

Comp stats:

-Win 7 64bit
-Already running 2- 5870, using extender to plug in a third card
-Mother board is Asus P5k Pro with both 16x slots already used and using the extender on a 1x slot.


Any help would be much appreciated!

Comp stats:

-Win 7 64bit
-Already running 2- 5870, using extender to plug in a third card
-Mother board is Asus P5k Pro with both 16x slots already used and using the extender on a 1x slot.


Any help would be much appreciated!

Try running one of the known-good cards on a known-good slot through the extender.  If that doesn't work, either there's a problem with the extender, or you may need to short the presence-detect pins as shown here: http://blog.zorinaq.com/?e=42

I've tried different cards and switched them around and all the cards are in good working order. I'll look into that link you sent me thanks Chris. More help please! I have 400mhash that isn't being utilized, the sky will fall soon if I don't get it working asap lol.

So using 2 power supplies with these is a no go?

Do you have trouble reading dude?

Didn't Inaba say that there are issues with grounding/frying parts? How would you hook up another power supply so that both would turn on when you turned the computer on? There are only guides on how to jump start it...

Just checked out that article and I see there are 2 pins that must be shorted if the motherboard doesn't allow down pluging. What is it I'm supposed to use to short it with?

Hey poker let me know if you fixed your issue please b eacause i h ave the same issue but with just 1 card in the x16 and one in the 8x using the 16x extender. Video card using the x16 extender isnt detected in amd's ccc and core/memory clock are at 0 on msi (this is with dummy plug installed). But if i plug in my hdmi cable into the video card using the 2nd hdmi port on my tv it gets detected on the x16 extender.

Shorting the presence detect pins should correct this issue, one would bridge pins A1 & B17 as in this picture:

A 24-ga wire should slide right into place without forcing.

This is something that seems to effect a small percentage of motherboards, while on the majority it won't be necessary.

Will the 1x extender fit underneath a GPU? For example my rig uses an MSI 790 gd70, with 4 gpus. I'd like to add a fifth using the pci 1x slot, but I'm not sure if I'll need to also extend the gpu that covers that slot.

Depends on the fan shroud on your GPU.  Most shrouds are too low to fit an extender in it.  Some aftermarket (and stock) coolers have some space between the HS and the board, you can run the extender up through the HS and then over to where you need it.

As far as the jumper goes for presence detect, all my motherboards required it, so I soldered the wire onto the extender. I will try to get a picture of it later today.

If you're searching these lines for a point, you've probably missed it.  There was never anything there in the first place.

ok, seems like I'll need to use a dremel tool.

Now the question is power: I'm already using a cpu->pci and 2x molex -> pci.

I have only 2 more molex connectors on the PSU (which has plenty of watts -- 1250)

Do any of these have a chance of working, and which is likely to be better:

1. Split one of the pci connectors
2. Supply half of each of two molex->pcie adapters from a single molex line, using these adapters in two different gpus
3. Split the CPU line (cpu is a sempron 145, and I'm running headless so cpu usage is around 5%. so draw on the cpu line should be pretty low currently)

It depends on whether your PSU is a single rail or multi rail. Also the gauge of the wire supplying the molex connectors should be taken into consideration. On some cheap secondary (~350W) PSUs I was using the molex connectors which had approximately 20-24 AWG wire, I melted both the molex connector and wire connected to a 5850 via molex to 6-pin adapters.

Ok shorting the pins work! If your comp won't pick up from a pcie 1x slot short it like this picture. At first it didn't work for me probably because I didn't have a solid connection since the holes are so small.

I have just received several of these cables and seem to be running into a problem not described anywhere else here.

If I have a card plugged into an adapted x1 ->x16 cable (plugging the extender into an x16 slot) the computer refuses to boot at all.  Using a combination of sapphire 5850s and 5870s on a Crosshair IV Formula motherboard.  This happens even if I am only plugging in one of the cards that works when plugged straight into the motherboard, so I am confident it isn't any sort of ATX power issue.  I have tried with, and without, the pins shorted as shown in many of the diagrams here.

I appreciate any help or insight anyone here may be able to offer.

Thank you.

Hi Thor, some motherboards will boot with the 1x->16x adapter plugged into the 16x slot, however in many cases you would need a straight 16-16x cable. Send me an e-mail to sales@cablesaurus.com and I can get a replacement in order if necessary.

I've also noted that some of the low-end microATX boards with one X1 and one X16 slot will not support use of both slots simultaneously.  I have a couple of machines with cards in the X16 slot to which I was hoping to add another card using the X1 to X16 adapter.

That'd be motherboard related if booting 2 cards wasn't supported, unrelated to using an extender.

Hi,

I'm having a problem with my third card. I have this motherboard and 3 5870. Two are in pci e x16 slots and working OK. I bought x16 to x1 converter to get the third in, but my computer doesn't recognize the third card - I can only see 2 in device manager.
I am running Windows7 and already tried the solution suggested earlier in this thread shortening A1 and B17. I'm sure I did it right because I checked the connection with multimeter.

For the 1x 16x w/Molex conector it states:
# The molex connector helps prevent physical cable damage and possible motherboard wear from running a dual-GPU video card through an extender cable

I don't know if I need a molex conector. Does this means it is better but not necessary in any case?

Take a look at this: http://blog.zorinaq.com/?e=44

If all you've got is one card, you don't need the molex connector, as the cable itself can handle the current that the card draws from the motherboard.  The problem is when you're running multiple cards, the power drawn through the motherboard all adds up, and can potentially melt something.

I don't know the exact point at which you need the molex connector.  I went with it for the single 5970 on my 5-card rig.  Maybe I could have gotten away with not using it, but I didn't want to take the chance.

Your picture is awesome. Smiley Do you have a Dummy Plug inserted into the card? That's likely why it's not detecting, in Windows a display always needed to be connected to your card, whether real or via GPU Dummy Plug.

Hi. Thanks for your reply. I think you are wrong. Dummy plug is not necessary for the card to be recognized as a device. In my experience dummy plug is only necessary to initiate GPU. In any case, I've tried it just to be sure with and without dummy plug. Also, I tried booting up with a monitor plugged in - no luck. One more thing - I tried taking out one of the working cards from pci e x16 and inserting the extender there, but it also didn't work. Unfortunately, the only conclusion I arrive is that the extender got damaged in transport although I cannot see any obvious damage. Is there any way to check it?

1x -> 16x Adapter will work for any 16x card from the 1x slot. Bridging is only used on generally lower end motherboards that have trouble detecting, and is independent of the card you use.

The 1x to 16x Extender will not work from all motherboards from a 16x slot. It generally must be used from the 1x slot to your 16x card.
Every card I've used regardless of extender requires a dummy plug to initiate especially with Windows, and must remain plugged in for the duration of the cards use. This is required for any non crossfired card.

Edit: Saw your PM that things are working now, thanks for the update.

I have this motherboard and the xfx 6950, i am thinking about getting another one.

So I'd get one of the x1 to x16, but would I need the molex connection?
And how would I put the gpu in the case as the cable would cause a gap between the x1 and the card wouldn't it?
Also how would I use that open ended x1 slot? would that mean that you'd have to take off the one you have and put that in its place?

Hi there,
- Molex connected cables are needed solely for 5970 and 6990 users
- We're working on our hardware chassis, pictures will be up this weekend and shipments will begin as soon as possible
- The open ended slot will fit right onto your 16x card, it is designed to fit your current slot and card

I thought  that power required on all pcie channels might cause problems like some slots melting or something.

It cant hurt and you are safe in case you want to upgrade to a dual gpu card, exchanging a psu is less painful than a dead mainboard.

I'm not aware of this posing an issue, generally the non molex modified cable would be fine in your case.

Currently out of stock of PCIe Extender Cables and will be back in stock this Tuesday the 7th.

Are you going to have an ample supply of these? I may need somewhere in the region of 15-20 of them for my rigs plus dummy adaptors. Would you be willing to offer me a discount for all these and also what is the quickest you can send them to London UK? Would extra charge allow for a quicker delivery?

Going to order a 1x extender cable once my latest bitcoin payout is confirmed and the cable is back in stock. Depending on how the installation goes, I'll probably order four more in the next two weeks and more after that.

I am in need of a quick fix. I have a motherboard coming today. I will be buying the extenders when they come back in stock.

However in the mean time, can I simply dremel the x1 slot on the motherboard?

Its for cards that have dual gpu's like 5970 or 6990 that require alot of power from PCI-e slots and its safer to have a molex connector to help power it.

Using the molex-modified PCIe x1 cables, and they work so far. Now I'm at the maximum of my PSU and will order a new one. Just a quick question: is it save to power a card on another PSU than the others? I basically have 3 cards already all on 1 PSU, and the fourth will be on PSU #2, and connect its 6/8-pin connector and its molex to this PSU.
Could there be a problem or am I on the safe side?

It's not safe, but it can be done.

Short a Green and Black wire on the 20/24 pin ATX connector using a paperclip shaped like a U.  Hook up graphics card.  Try to figure out the exact timing of turning everything on.  It needs to be near simultaneous, but not quite.  Basically a few milliseconds after the main PSU starts the dedicated one needs to be switched on.

Although not all PSUs will power on like this, some need a constant draw device like a case fan hooked up to a molex connector.

That's no problem since I have an ATX 24-pin splitter that turns on both PSUs simultaneously. What I'm wondering is whether it creates some sort of power differential having the motherboard on one PSU and a connected Graphicscard on another.

It's fine.  I've done it the way I described successfully once, so a splitter should make it easy mode.  They make special supplemental PSUs for graphics cards that fit in 5.25 bays, I'd assume the work on the same principle.

Just got my order -- excellent service.

I can't seem to get it to work on my particular machine, but I doubt it's the fault of the cable. Don't know whose fault it is!

I have a XFX 6870 that needs to connect to a 1x slot. I bought a 1x to 16x adapter (among other things).

My machine is currently using 239W, running a 5850 on the first (and only) 16x slot on the mobo.
The power supply is 650W Corsair  -- so I should have plenty of headroom for a 220W card.

My 650W PSU only has 2 6-pin PCI-E connectors (which are being used) so I used the Molex-to-PCI-E adapters that came with the card.
This card requires (2) PCI-E connectors.

Anyhow, I connected everything up securely, turned on the PC, and it stayed on for about 15 seconds before shutting itself off. I never got the "all clear" post beep.

Advice?

I just got my order today in the mail, and I have to say, it was very exciting to open that package. Not because it had some random cables in it or anything like that. It was amazing just to have in my hand a physical product, something very real, that was purchased entirely with Bitcoins. What a profound message on the reality of Bitcoins. I almost want to frame the cable and hang it in my room  Tongue

Anyway, works great. Thank you.

Hi Matthew,
It sounds as if your card is insufficiently powered. You would need to use 2, 2x4-Pin Molex -> PCIe adapters. So, you'd have 4 molex connectors being turned into 2 PCIe connectors. Using just a straight 1x4-Pin Molex -> PCIe won't do the job usually... even if they came included with the card.

 hmm didn't have any luck getting a 1x extender working on my rig

1x extender with end cut off

p5w DH Delxue

2x sapphire 5830 in 16x slots and another sapphire 5830 attempted to plug into 1x slot

if i boot *just* the 5830 in 1x it works fine (no jumpering)
if i boot *just* the 5830 in 1x and a single 5830 in a 16x it works fine (no jumpering)
if i boot all 3 cards only 2 of them show up, and there is a PCI Express Root Port in device manager with a Bang for error Code 12.

Tried disabling audio chipset, 1394 controller and 2x pci-e onboard gigabit NICs without any change

Anyone have any ideas?  this is going to put a cramp in my mining for sure...

This is an uncommon limitation in power distribution for your motherboard. A molex cable would likely solve your issue, send me an e-mail and I can arrange setting you up with a replacement.

- 890FXA-GD70 mobo. have plenty of power
- Windows7 x64. sdk2.4 video driver 11.5 or 11.6
- received the PCIe x16 extender today and attempted to use it.


The system is completely unstable.  BSOD (from video driver) or it simply freezes.

I don't even begin overclocking anything (not enough time to get that far before issues occur).  Stock settings.

if I take out the 4th card the system runs just fine... not using crossfire.

Does anyone have any ideas about this?  Have you experienced this too or have you heard about it?

Doesn't an 890FXA-GD70 have 4 usable x16 double slots? I glanced at the photo at MSI to refresh my memory and it seems like it does unless the board is snug up against the side of a case in which case you couldn't fit that fourth in there, hence using the x16 extender I guess huh?

What PSU and what CPU are you using? I understand you believe power is not a concern but if your rails on not properly balanced you could be overloading one of them. PSU & CPU model?

Of course it would be ideal if you could slot that fourth card on board w/o an extender to test.

Of course it would be ideal if you could slot that fourth card on board w/o an extender to test.
AMD Phenom II X2 555 CPU
ST1500 PSU

So I had to get creative since the last slot is not that well suited for a double-wide graphics card...
AN installed card not only covers the on mobo power/reset/OC buttons but also interferes with the case wiring...
Anyway, after shortening the pins on mobo and cutting the connectors in half, I got it in there... it a tight fit.

Everything works fine...

Conclusion:

1 - recieved a bad extender cable...
2 - the molex splitter does not draw the same power as the card would from the mobo.  and this probably causes issues I've observed...  I may be 100% wrong on this one, it's just a hunch... Someone else may be more knowledgeable to explain.

Well with that PSU I concur that it is most likely not a PSU concern. I will assume your PCIe 6/8-pin power is marked per rail and you are connecting each 5830 to a single rail. Even if you shared a rail between two cards it probably wouldn't matter much since the alternate rail would fill in the slack.

Did you get an x16 extender with a molex power connector to supply PCIe slot power via a molex peripheral or just a standard x16 extender no molex? I didn't understand what you meant about the "molex splitter".

Something to keep in mind though when using these PSUs with multiple rails is how the rails are wired. I had to get wiring schematics from Seasonic to make sure I was balancing my loads on a dual rail PSU. The molex peripherals, CPU 12V, ATX and misc are on one rail as well as a couple PCIe 6/8-pin power cables and the other rail ran a couple more PCIe 6/8-pins.

It sounds as though you are safe on rail load balancing though. I would hope that Silverston put CPU/ATX/Peripherals all on a rail (or two) alone.

I would probably lean toward a defective extender.

Some new products being added Tuesday:

* PCI -> PCIe Adapters (Which will run your card even through an extender, at full speed, from a traditional PCI slot)
* Kill-o-Watt meters

We've also recently added:

* DVI Connector GPU Dummy Plugs (Direct DVI connector)
* VGA Connector GPU Dummy Plugs
* DVI -> VGA Adapters
* Molex -> PCIe 6pin PSU adapters
* Chassis stacking kits

Pictures are on the way as well!

I want to modify one of my pci-e x1 cables so to give it power from the psu..
I see that there are 4 pins giving 12v .
http://en.wikipedia.org/wiki/PCI_Express#Pinout
(A2,A3,B1,B2).
But I sow that someone re-routed 5 pins instead of 4 pins...
http://blog.zorinaq.com/?e=44

Can you help me and tell me how many pins do I need to re-route?
Thank you.

Mine only when pc is IDLE totally indivisible...

Just to let everyone know -- the cables worked out OK.

The problem I was having? It seemed to go away when I just re-seated both ends of the cable. I guess the lesson is "Those cables have to be 100% snug; connected all the way or they don't work". It isn't like I put them on half-way or something, either -- I just "pushed harder" on both ends, tried booting again, and it worked.

So if you're having trouble, try re-seating both ends of the cable.

So I would have to get the molex connector if I've already got 4 cards running the "normal" way and I want to add 2 more cards using these adapters?

Bought 2 with express shipping. Hoping to get this week.

Quote from: AngelusWebDesign
I just "pushed harder" on both ends, tried booting again, and it worked.

Had that problem with a 6990 too; It just wouldn't detect in either Linux or Windows.
Turns out the little pci-e teeth were ~0.05m raised. Had to push them in tightly and suddenly it worked fine.

So nobody should panic if cards don't seem to work at first

If I already have a 6990 and 6870 running on my mobo, and want to add 3 5830's using the x1 adapters, do I need to get the molex ones or not to avoid mobo damage?

Just to give credit, where credit is due. One of the extenders I ordered and received last week was bad. I contacted Cablesaurus and they promptly shipped a new one. Got it today and works great.  Cheesy

So, thank you and keep up the great work!  Cool Buy things with Bitcoins is lots of fun.

You may want to put one of the extra GPU's under a Molex cable.
Molex cables are useful for those running 5+ GPU's under one rig.
