Hi there!

I bought on ebay pci-e cables that are 6p on one end (This plug into the breakout board of PSU) and 6p+2p on other end (this plug into your GPU or wherever you need them)

I am using 2 cables per GPU and never had any issue. But I did screw up when i connected only one cable to power my Octominer mining motherboard, and then the plug burned, now i am using 3 cables to power the motherboard.
I use 17 port breakout board from ebay, these work great for me, and the one with 12 port, i didn't like so much, i think the connectors on them are not as good as on 17 port.

If you don't mind the noise, powering 6 vegas (optimised, of course, not at default settings where they pull 300 watt each) is easy with this PSU. Now my rigs are 8 GPU, i just use 2 1200W PSU, one powering 4 vegas, another 4 vegas and a motherboard, and that works nice for me and PSU is not as noisy as working with 6 vegas.

if you connect 2 separate PCI-e cables for powering the Vega (actually, vega will not work with one cable, both must be plugged) you will not have issues with burned connectors or instability. My only fuckup was that, powering a mobo with only one cable, and that was on 12-port breakout board and the plug burned. I think it was the plug fault on breakout board, not the cable itself.

cheers! Smiley

A 6-pin can handle more then 75 watts of power. For example if a 6 pin were restricted to 75 watts then we would be getting  2.08A per 12v yellow cable 2.08*3*12 = 75 watts , but awg 18 are able to deliver up to 10A per yellow under optimal circumstances  , so theoretically  10*3*12= 360 watts.  But thats the cable then we have the terminals..

Standard terminals are rated for 8amps then  there is HCS terminals that are rated for 11amps and Plus HCS terminals 12amps

so with a 6-pin pcie  with 2*8*12= 192 watts from 6 pin pcie 18awg
               8-pin pcie with 3*8*12=  288 watts 8 pin pcie 18 awg   

So 6 pin 75 watts of power rating are vastly underrated.

I getting fed up with people who don't know how to use their system then come here whining without
providing any useful information. I will no longer ask. If the initial post has insufficient information I
will simply ignore it.

Dual CPU systems and their operating systems are much more complicated that regular desktops.
Learn how to use them properly before complaining here.
