Can you make 18" PCIE extentions with 14 or larger gauge wiring?
How about some 24" PCIE plugs that terminate in ring terminals?

Was looking to make 2-headed cables similar to what many psus ship with, but using quality 16awg wires...
where are you on this? I am interested in 2 headed cables
What are you trying to accomplish here? I may be able to work something out for you.
Was looking to make 2-headed cables similar to what many psus ship with, but using quality 16awg wires. I was informed that the molex pcie crimp pins do not fit two 16awg wires, 2x18awg is the max
Ah, I see. But why would you want to increase the load so much on the 16awg lead by adding another terminal end? I would think separate leads would be cooler and safer. Is it a space saving issue?
Anyway, just between you and me and the wall I can do double 16awg wire crimps even using the wire you sell. It takes a bit of finesse and patience (and a couple of tricks) but it can be done correctly. It is the method I use for making my 2:1 reverse adapters for Neptune/Titans.
mostly for people who like filling all the connections on stuff like the S3, or multiple lower power devices. Would also mean 6" of wire for the second connector as opposed to 24", saving some cost and shipping.
Mostly just interested in what sort of wires people are interested in, as the majority of interest is the leads, but I also go through the 18awg splitters pretty quick.
ANYways: I now have >500 leads and 100 splitters in hand today

ps: im looking at the possbility of 36" cables or other esigns in the future - any requests or thoughts? (ps: i cant strand two connectors on a single 16awg lead - the cable is too thick - hence the splitter)

anything outside of North America is pretty expensive (its about 1kg for every 15 cables), taking several weeks, and I think european vendors offer cables more locally.
Don't need many, only 4 PCI leads 16 awg cables. Ready to wait several weeks. This cables quite expensive from european vendors http://shakmods.com/shop&#!/16-Gauge-16-Awg-Un-Sleeved-PSU-Cables-Titan-Neptune-mining-cables-Pci-e-GPU/p/37642162/category=3316088
+ 2 x PCIe-to-PCIe
If you are interested, Could you check for the final price

Do you carry out international shipping?

orders of 100+ can possibly be arranged for direct shipping from the factory though, which is a very affordable method if you can wait ~2weeks for production and shipping

I got my splitter in perfect shipping package.
Solid wire!
Thanks Klondike

bump to the top - great for server gear conversions like the sidehack boards!

time to bump this again.
im out of the PCIe-PCIe cables (maybe 4-8 of them left), but have hundreds of PCIe leads and over 100 of the splitters

I've gotten these before, solid.
I'm an aircraft electrician, so figured, I'd buy the materials a nd build them. After wiring a single S3+ I said screw it, wasn't worth my time.
Wish you would offer some cooler wire
Maybe some of the UV stuff, Really pimp out the server room

Maybe some of the UV stuff, Really pimp out the server room options like that are available - I could use wires other than black/yellow but IMO it would overly complicate things and cost a little more. In my experience most buyers are looking for 'industry-standard, professional' stuff like yellow/black wiring and black connectors though.
sleeved wiring and UV stuff should be possible, but there is an MOQ of 1000 units for most of these complex designs.

$2 to add another PCIe socket seems worth preventing several hundred in damage
More like .2$ for the socket, and it's probably even close to 0.05$ in the bulk quantities they are using.Standard rating for the crimp pins is 9A, so we should be safe up to 324 watt (3x9x12), and it already include some safety margin from the manufacturer.
If you read the datasheet, it gives a numer of mating cycles.
After this number, the material of the pins won't give a contact between pins as good as when it was new, and even in this case, you will be able to draw 9amps per pins with some safety margin left.
But as you said, any imperfect connection will ruin the connector, so using the cables around 250/270 watt is a better idea than to max them out at 300-350 watt.
all it takes is an imperfect mate on a pin, and that 9A of current is suddenly traveling over 1/2 or 1/3 the surface area that contacts the pin to the cable. bam, fire.
and yeah, PCIe sockets are cheap in bulk. my $2 figure was an upper bound for the cost of the part and the slightly increased complexity of the PCB and assembly. There's no reason to require all that power through a limited number of connectors.

^ahh - looking at some reviews and failure images i see you're right, and 350-400W draw is possible at higher clock settings (thats stupidly dangerous even if you had a 14awg PCIe)
a lot of failed neptunes seem to be burning out the PCIe ports rather than the cords though, because all it takes is an imperfect connection to jump a spark or move the load to a different wire/pin and fail the unit.
my advice would be to use my 16awg wire and try to operate the neptune at a setting thats <350W draw. The cable should be fine, but might get warm enough that you want to consider adding a bit of airflow around the wires. As i mentioned before ive been able to do 320W+/cable myself, but any design that demands >250W/PCIe (im looking at you too, sp20) should really just be building extra sockets into the equipment. $2 to add another PCIe socket seems worth preventing several hundred in damage

more like 400w! 5 cubes at a total of 2kw is 400w
i don't have neptunes, but sp20, and i got a lot of smaller psu's that i want to use on sp20

Do you have 2 * 6pin pci-e to 1 6pin pci-e? like a converter from 2 to 1, like the knc should have shipped with their last miners...
thx!
thx!
not 2-to-1, sorry. I have 1-to-2 splitter though.
Not trying to poach your thread KB but I can do this for the KnC miners.
no sweat - but honestly from what im reading, the neptunes pull about 300W through the PCIe connectors. That is pretty reasonable for my 16awg cables to handle (ive tested them to around 320W without any major concerns), and building in a splitter wouldnt significantly improve things

new cables are with the fedex delivery guy right now, should have them available in the next few hours.
I've re-designed the first listing with more detailed prices, specials, and to properly price the different cable types
