You have the same link for the different PCI-E cables.

I don't have ASICs but I don't see any issues with your setup as long as you plug each of the 12V leads into different slots on the breaker (like on the pic but with 9+9) and if you properly cut and prepare the leads.
Basically, the L3+ apparently has 4 boards each of which requiring 2 x 12V PCI-E connections (and the 9th to power the controller board). So essentially 800w/8 =100 watts per 12V PCI-E which is 8.3 amps and 16AWG wires are rated much higher than that (16A maybe?).
Maybe others can chip in as well.

Cool thanks a bunch! Yeah sounds like in theory it could work but I don't know enough about this stuff to say for sure. But yeah as you say, 9 negative (3 leads in one slot) + 9 positive (3 leads in one slot) - in theory might work? Thanks again, any other input would be great. I'm also struggling to find the proper forum / place for this question! Greatly appreciated thanks.

Shit ok, so won't be able to put 3 wires into one 'slot / hole'... damn. Ok back to the drawing board I guess!
Thanks

It should be all good though, just remove the other 4 cables from the 6 of the PCI-E, you can see the difference (6 vs 2 wires): So only the middle two wires matter, the rest doesn't need to be plugged in.

Ah right, I thought the 2 lead one was thicker or something and so could provide more power. But you reckon it's just the same but only 2 leads? Guess that makes sense...

I believe so since the 2-wire cables are advertised to be working with popular ASICs.

Damn. Ok solid point, will check it out and make sure there's enough power if I just used two leads per connector. Just thought they were separate leads somehow. But would make my life a lot easier if they're the same type just with fewer leads!
Thanks for all your help buddy

If you can wait why dont you buy one from a member on here called "sidehack" he makes breakout boards to fit the dos server psus with 12 6pin connectors on. I have two of them. Great baords and great quality. You could also try www.bitshopper.de as he stocks the boards made by sidehack in his store. I bought mine and associated cables from there. Link to the shop:- https://www.bitshopper.de/shop/?lang=enAlso DONT reduce the number of cables per 6pin plug, you are asking for trouble (fire) if you overload a single wire.

Fuuuuck didn't realise this place existed!!!!!! I would have but already have the breakout boards being delivered.
Just need to work out how to power them properly via PCI-E - but sounds like I can just use standard 6 pin PCI-E cables and only use 2 of the wires on each...
thanks though!

I am making my PCI cables for server supplies with only 2 cables each plug using 1.5mm2 cable. I have 27 sets to make for the new setup! I wasted so much time making 6 cable plugs it rediculous! As long as the cable rating is well over what each plug is supplying the 2 pin cables will be fine.
