I stock Belden wire, but that one looks like the same specs.
Probably is. as Weico naturally has cross-references to most of what Belden and the other major mfgrs make. Difference is we don't pay for the distributor markup They are more than happy to mail you some samples to verify the wire characteristics before placing a large order.

I'm surrounded by one hour at the Molex site... Incredible, how many parts what they look identical, have differnt uses... this seems all the same PCI-e 2 row 6pin female pins but what is used with PCI-e power cables??? no code are printed in my PSU standard cables... so, how to understand.. http://www.molex.com/molex/products/listview.jsp?channel=products&fs=category:Crimp%20Housings,productname:%22mini-fit%20jr*%22,application:wire-to-wire,gender:or(female||receptacle),numberofrows:2&sType=z and i found flammability standard too... UL 94 -0 ,1 and 2... googling i found http://web.rtpcompany.com/info/ul/ul94v012.htmi think UL 94-0 is ok???

Yeah it gets pretty complex with all the choices available. The part number for PCIe connector I use is 45559-0002, you can see it on the Heilind link https://estore.heilind.com/45559-0002/MOL45559-0002.htmlIf you scroll way down that page there are the female pin terminals that go inside of it. They have many options as well, such as gold plating, etc. The cheapest option there looks like part # 39-00-0077 which is tin over copper plated brass. https://estore.heilind.com/39-00-0077/MOL39-00-0077.htmlEdit: After rereading your post, maybe you are asking what part plugs into the PSU itself? That tends to be proprietary by manufacturer of the PSU. Most of the people that I've seen making their own cables use server PSUs and choose their terminals based on what fits the blades or they direct solder.

Do you Know if Weico have EU dealers? No idea but if they do odds are it will cost more because any importer/reseller has to make money and that comes from their markup on reselling wire or other products. Just ask Weico. On the website they do advertise international shipping but no doubt if shipping to the EU there will be VAT to be paid... That said, the cables certainly are a business expense so I assume your country lets it be a tax write-off no? And I still think it would be faster/cheaper to just get the cables from Sidehack....

thank you for the tip... but i confirm who is not convenient to home build cables.. For connectors, Heilind is more convenient: https://estore.heilind.com/45559-0002/MOL45559-0002.htmlbut maybe, it is mor expensive for shipment... I think RS have EU dealers too. it is more convenient to buy cables from good sellers like sidehack or Finksy!

For a big order like that I can give a pretty good discount. Message me if you want to talk details.

On a related note, you didn't happen to find a source for the Dell Z750P backplane connectors that was cheaper than multiple dollars each did you? I remember last time I looked they were wanting $7 a piece or somewhere along those lines and didn't have any in stock, with a backorder time of months.

No, it's pretty much a factory order part. $7 apiece is quite a bit more than I typically spent but then we bought several hundred at a time.

Those particular ones are not PCIe connectors. Same general family yes but not the correct ones. The site shows the 3mm-pitch (pin spacing) version with a 5A rating and max wire size of 20ga -- too small. The correct PCIe connectors as shown on https://estore.heilind.com/45559-0002/MOL45559-0002.html are 4.2mm pitch, actually a 9A rating and up to 16ga.... Even the data sheet linked http://www.molex.com/molex/products/datasheet.jsp?part=active/0455590002_CRIMP_HOUSINGS.xml clearly states that is is PCIe (tm) and what they are for. Just another reason that when it comes to large undertaking like 1,000 cables, unless you already have the know how, equipment, and time to do it right, DIY is not ever really an option... Far better to pay for them pre-made by someone who has already done the homework and investment involved.

i think this is the most impontant components! I tried to diving into all this standard... wire and connectors, but if you have not a massive know how, you risk to loose time, money and if you do the wrong things, you risk to bust your miners...
