Has anyone seen this issue or have experienced something similar?  The power usage for random cards on the rig will drop drastically at random times.  Hashrate doesn't seem to be affected, so I really haven't done any physical troubleshooting yet, like switching power supplies etc.  

This rig has 5x1070ti on a Corsair 1000t PSU and 2x1080TI on a 1500T Corsair.  It will happens to GPUs running on either of the PSUs.  I have a couple other rigs that run EVGA PSUs and have not seen this happen, so i'm wondering if this is something related to Corsair?

No it has nothing to do with your psus.

Also do yourself a favor and drop the 1080tis to 200 for the 215 one and to 210 for the 230 one

If your internet connection isn't stable, sometimes a gpu will not have any work to do for a moment.  Even on very stable connections this occasionally hapepns.

Thanks - That's actually something else that's goofy with this rig.  Both 1080tis are the same make/model but one uses more power on the same PL.

Thanks - Probably isn't the case since I'm running several other larger rigs on the same switch with no issues, but I'll keep an eye on it since it could be something goofy with running these rigs through a powerline adapter.
