OK, will it sounds like your PSU and topology is thought through, so maybe leave that for now.
Could you post the debug log, from the batch file I added above?

(Just to rule out the pool angles, as I have no experience with suprnova, and Ethermine, being pretty much the biggest there is, makes for a good choice when testing, even if you don't plan on mining with those guys).

Now that said, what SHOULD be happening at this stage is the init of OpenCL, (or CUDA if you're using Nvidia).
OpenCL is managed via the AMD driver, so assuming you don't have a problem with the pool, I think you need to investigate if OpenCL is available.

One way to do that, (with a only single GPU in the rig), is you use GPU-z, and see if the OpenCL check box is populated.

Now, I have also seen perfectly good working rigs, where that checkbox is NOT populated, and clearly that is wrong, so to be absolutely sure, you (again with only 1 GPU in the rig), could boot to safe mode, DDU, reboot, install the AMD driver, set to compute, reboot, and check GPU-z, I have never seen that fail to confirm OpenCL.

From there, try my batch file again, and post the log if you're still stuck.
Good luck

Also, VM? Set to 48000GB if need be.

Foot note, in case anyone needs convincing of the single GPU method. If you do a clean AMD driver install with 13GPU, this alone can take hours, more so, if it fails, and AMD themselves STILL have an open bug on init fail with more than 12GPU.

Often when testing theories, working through troubleshooting etc, this is time consuming, and for sure you probably work at testing, (proving) some angles that were perfectly fine to start with. Time is not wasted of course, as you can cross those off the list, elimination of them, takes you closer to the answer.
But all the same, if you have multiple GPU, that's an exponential multiplier on the possibilities of fault, and means more time to troubleshoot is a given.
Breaking it down to basics, (you only need to pull the USB cables from the MB, for the most part), is pretty quick, you don't need to physically remove the GPUs etc, means you can run DDU, and reinstall the AMD driver with the minimum time consumed, and get back to starting Claymore as quickly as possible.

AMD driver install time, is pretty acceptable with a single GPU, but 12 and 13 is really nasty, and I have seen that fail many times, so working on proof of concept with a single GPU is by far the fastest, and most likely to provide solutions imho.

BTW 18.3.4 is a stable driver for mining.
Note: there is NOTHING mentioned in any release notes from AMD, on any mining related improvements in the drivers release since 18.3.4.
That is not to say the newer drivers are bad, (some are though), but simply, 18.3.4 has been out for a while, rolls up all the mining related things you probably need for RX570/580 hardware, and has proved itself far more than any of the drivers released since then. So, if you're going to DDU etc, I'd suggest 18.3.4 is a good choice, known good, known stable, well proven choice, and when you're troubleshooting, you need to focus on elimination of doubt. Go with what you know, (is good).
