Hi,

I'm going to order 8 or so risers (will only use 6 GPU's but wanted two extra spares just in case) but I'm not quite sure what to pick. I've also got a question for you experienced miners regarding PSU cables for the risers. So here goes.

Should I order risers with 6-pin connectors? If so, can I power 1 GPU and 1 riser with the same cable from the PSU? If not, then the cables on the PSU won't be enough.

Or should I order risers with molex connectors? If so, can I power two risers with one cable from the PSU? Also, the EVGA G2 1300 that I've purchased only have two cables with molex, would it be possible to take another one from my EVGA G2 750 that I'm not using? I'm assuming it's the same cables. Can I plug the third molex cable (on the PSU side) into one of the ones that are supposed to be for the sata cables (there are only two peripheral slots on the PSU)?

Thank you!

most PSU these days have limited molex connector, and have a tons of sata connector
and most sata cable will be burned out to flame on RX GPU, so there are no place for sata in mining rig to be safe
since pcie 6-pin cables are limited, and even more limited molex, it still better to use pcie 6 pin cables since their spec is designed to deliver up to 150w (molex is only 50w, sata is only 35w)

so the solution is just use PCIE 6-pin splitter, one end for riser, and another one for gpu, so each gpu+riser only use one cable from PSU

Is this the cable?

yup that it is, only use pcie splitter that use at least 18 awg wire, 16 awg is better, but never use 20 or 24awg wire
