Power connectors for GPUs
#1
I'd like to upgrade my hashcat rig, a 4 GPU box. The PSU can deliver more than enough power (pro redundant rack hardware), cards are on real (physical, not lane-wise) x16 slots but the number of physical connectors on the PSU power backplane is limited. So now I've got a bunch of options. What will work / will be the best option according to you pros?

1) 1080Ti connected with a single 8 pin power connector only. Will it work to start with? If so: e.g. power limit on 225W?
2) 1080Ti connected with a 8 + 6 using a splitter (reading advice telling not to use them).
3) Use 1080s.
4) Something else?

And in general:
- How many Watts can you safely pull through a single 8 pin GPU power cable?
- How many Watts will a 1080/1080Ti burn in -w4 mode, worst case seen and what cracking mode will that be?

Thanks!
