As I expand out my new mining rig, I’m running into a lot of different configurations for PCI-E risers, and I’m pretty confused.
Let’s say I want to run 6 RX 580’s cards on this rig, and that I’ll be using these 6 pin PCI-E risers:
and that I’ll have a server power supply with a breakout board powering the GPUs such as:
and a seperate PSU powering the mobo.
In order to successfully power the rig, am I correct in assuming that I will need to use 6x 6 pin cables from the breakout board to power the PCI-E risers, and 6x 6 pin -> 8 pin cables from the breakout board to power the GPUs? There also seems to be SATA powered connections (which look to be pictured in the PCI-E riser picture above), but I’ve heard people say to not use those.
Or, is it optimal (and safe) to be using only 6x 6 pins from the server PSU, and using these splitters to power both the card and the riser:
Thanks in advance you guys, and apologies for the noobie question
