Careful with this version, while people report no major power increase, if you ever watched the gpu power consumption in gpu-z, you will see that each card has a power spike when it finishes a share (or something in the same ballpark). If you take the avg power consumption, it might look ok for the PSU, but those spikes, if they are done at the same time on most or all GPUs, even a relatively good PSU will make the system freeze or even shutdown.

Just to confirm, there are some big PSU spikes happening.

Same here. I'm running 7 rx 480 on a single rig and had no problem with v.8. I've had to set -i 1 to stabilize the system. I'm using a Platinum EVGA psu, so its not that. Anyone have any insight?

How much power for the PSU? The fact that it's platinum means very little.

Well, my Platimax 1200 has problems ( freezes ) with 6 480's. No problem with 5 of them. PM shows 850 - ish @ the wall so not registering spikes

A regular wall meter cannot tell because the spikes are really short, but enough to trigger the PSU's protection systems. So only with a high update rate wall meter you can tell.
Are your cards overclocked/overvolted?

Underclocked.... I have other PSUs, looks like Platimax is the most sensitive to this. HX1200i is just warmer but not freezing, Navitas 1250 too

My Corsair AX 1200W monitoring software can see the spikes. they are also there in the V8. But V9 is more obvious.
