Re: [SUCCESS] 7 GPU Mining with Asrock H81 Pro BTC + PCIe Switch/Hub
Regarding cables:
Yes, I've always made cables. Been selling PSU breakout boards for a little over three years and they've always shipped with in-house-manufactured cables.
The cables I made for this build are 24" from EVGA 8-pin PCIe (and CPU) split to two PCIe 6+2. 18AWG wiring is necessary for doubling up in a pin (double 16AWG is too much wire for a solid reliable crimp) but that's still good for about 150W per end, meeting PCIe 8-pin spec.
Not sure if they're in use in this build but I also supplied some 6-pin to 4-Molex for riser power, plugging into the EVGA's SATA/RERP ports.

Yup, thanks for them. And yes, your cables are being used. Each riser and each GPU is independently powered from their own ports on the EVGA power supply, except for one port is powering 2 risers because of my 7 GPU set up (My powered risers are the 4 pin molex, I don't feel comfortable using those sata to molex adapters so I had sidehack make some molex ends for my PSU).
Here is a diagram of my setup in-case anyone else is interested:
(Note: Riser 5 is on a molex split because I needed a power source for my SSD.)
