Hi there,
I believe i'm having your exact power spike issues, even with good quality PSU's Corsair HX1000i. I was wondering if you have any developments on it?
So far the ways I have alleviated it is by using the -gser 3 option and -lidag 3 to create artificial delays between the GPU initiation and power spike which works about 50% of the time. In windows 10 it will not cause the spike until the miner restarts at some point, then the OCP kicks in and rig switches off. If i use SMOS it will cut out at the exact same point each time. (when OC is being pushed to cards around the "creating GPU DAG buffer" part of Claymore boot)

Hi,
I have been mining for ~2 months now with 0 problems. How? Well, when the first AMD drivers that had the "Compute" mode came around (I think it was 17.11.1. Now I am on 17.11.3 and I am thinking of installing the latest but you know how it goes: if it works, don't fix it), they made the difference.
BUT I did not install them without problems. After installation, my rig worked for ~1 day with no problems, but then the miner crashed and it would not start again! It got stuck at the DAG file generation.
After some thought, I took the long way and formatted my drive. Clean install on everything, latest drivers etc. And... the same thing! 1 day of 0 problems and then the miner crashed. After research, I found out that it was the damn windows update that messed something up (at that time, the creator's fall update had just been released -I think it is relevant, that's why I am mentioning it). So, I performed another format, made sure I blocked Windows Updates by any possible way I could and voila: 2 months of no headaches.
So, if you haven't tried it already (because you are bored like I was, or something like that) a clean Windows installation will probably solve your problems. Search around for ways to block Windows Updates (it is a bit tricky on Windows 10) and whenever a new driver comes out resist the urge to install it if your system works well.
A final tip: just after a clean Windows install, proceed to install all your drivers EXCEPT your GPU drivers. Also, install all your software (like TeamViewer, HWInfo etc), perform any system configuration you want but do not install any gpu drivers or any Claymore version. Once you have done that, create a restore point AND do a full backup (there is a Windows 7 backup utility within Windows 10) to an external drive. That way, you will not have to perform a clean install again if something goes wrong with your drivers. That saved me a couple of hours so far and will definitely save me a lot more in case something goes terribly wrong in the future.
I Hope I helped
