DIY PCI-e cables for S5, S7, R4 and S7 ASIC

[unsoindovo]

Hi all!
I need to assembly 1000 PCI-e 6pin cables, 60cm long [24 "] to use with S9 ASIC.
Some one can share info about where to buy connectors and cables
And what it is Necessary to assembbly it?
I think, i need crimping tools .. but wich type?
I think to use 15 AWG, 1.65mm2 cables ...
It is enough
or it is too thin?

thank you all.

Where are you located? I custom manufacture 6-pin PCIe cables using 16AWG wire (and other things - splitters, extenders, 8-pin/6+2 pin, 4-pin Molex etc with 16 and 18AWG) if you want to PM me for a bid. I'm in the US.

If you're talking about a cable with 6-pin on both ends you're looking at 12 pins per cable so 12,000 pins. Unless you buy a press, if you're just using hand crimpers that'll take weeks. Before I had a pin press I could reliably expect about 500 cables in a 40-hour week if your hand didn't cramp up and fall off first. That's if you have wire already cut and stripped; this takes much longer than pinning to do by hand.

i'm in EU...
can you indicate me some e-seller?
Wath do you mean for "press"
can you share some pics???

I don't know any cable manufacturers in Europe. I've shipped to Europe before.

A press is a machine for crimping pins. Pins come on a reel, put the wire in the right place and hit the pedal and it crimps the pin and advances to the next one on the reel. Not a small investment but definitely speeds things up. If I had enough wire on hand I could make your cables in 3 days.

Good pricing and excellent delivery time for most types. Amazing how fast one can go through 5k-ft spools eh?

I still hand crimp, but an automated cutting/stripping machine was a lifesaver. Something like $900 on ebay. Cuts more wire in 10 minutes than I could in 10 days, and now all my wires are the same length!

Make sure you swap out the feed cone to the right size if you're using 16 awg. Mine kept jamming when I first got it and it turned out the cone was too small.

Also when specing cables: we assume Female for the miner end but is the other end stripped/tinned or terminated with Male or Female PCIe plugs?

I buy through a local electrical supply outfit. Good to support local economy, I don't mind paying a bit more because of that, and sometimes I get advice on things from the guys working there. It was nice to get a second opinion on things when I was figuring out the 400A 3ph service upgrade at the shop to expand hosting a while back.

I've got enough wire on hand for about 1100 cables of my standard 18" length, but for 24" a restock is necessary.

I was also lucky last summer to find a 30-odd year old crimp press in need of maintenance about 100 miles away. Picked it up, rebuilt the clutch and a new drive belt, bought some used tooling and have probably run 50,000 pins through it since then. Compared to hand crimping, it feels like cheating. Now if only I could find a good way to do sheathing. People keep asking for sheathed cables but putting on sheath without the ends fraying, and heatshrinking both ends, takes every bit twice as long as all the other assembly steps combined.

Any tips on the wire choices? I've been buying 16 AWG PVC coated off amazon, but I notice they have 500ft THHN for ~$22. That's about a third of what I've been paying, but it does have a thinner jacket.

Jacket thickness only affects voltage rating and and durability.  As long as the voltage rating is good and you are not abusing the wires (crushing, abrading against edges, etc.) thin jackets is fine. Aside from that, the number of strands matters and can affect price as well as the wire stiffness with fewer/bigger strands (eg MTW or building wire) being stiffer/cheaper than hookup wire.

if i read well they are in NY..
try to ask some quote for stuff+shipment...
thankyou NotFuzzyWarm

can you share some brand/model plz.... i'm completely new in this things...
but if the price is under 1000$ could be a good deal!

a think leave AWG standard could be dangerous for the farm security against flames....
but i repeat.. i'm not an authority here...

[NotFuzzyWarm]

AWG or CM only apply to the wire core(s) diameter and has nothing to do with the insulation. The wire ref'd above all meet UL and CSA flammability standards within their voltage and temperature use ranges

no experience to suggest... with some sellers on alibaba or aliexpress??
can you share some dealer?
just to compare price and quality with http://www.weicowire.com...

Weico is not a reseller - They are a manufacturer of wire just like Belden, Carol Cable, and Alpha who are the major makers of wire/cable for the world. With them you know exactly what you are getting. Only difference is that Weico also does direct sales vs using only distributors.

ok i understand...
Weico can sell to private/final users too!!!

[NotFuzzyWarm]

Yes.
The only 'difficult' part is sorting through the specs you want as they make many different kinds of and often specialized wire and cable. Generally just standard flame-retardant 300V 80-105deg-C PCV hookup wire is fine for low voltage work in dry, oil-free areas.

Usually the thinner insulation's are found on semi-flexible wire made of fewer but thicker strands of copper. Look for something like Weico's # 3016 http://www.weicowire.com/image/pdf/hookupwire/UL1007%20SPEC.pdf which has 26 strands of 30ga copper in it so is rather flexible.

For the number of cables you want and the amount/cost of the wire used you must pay attention to these details...

[sidehack]

I stock Belden wire, but that one looks like the same specs.

As I posted ^ the thinner insulation usually means the wire is semi-flexible and has thicker strands in it so verify the strand count. For 16ga hookup wire 26/30 (26 strands of 30ga) is good and flexible.
