I'm worried that the pcu may be just a bit to weak for this set-up as I get some random system shutdowns lately. Max usage of the GCU is apparently 321W and that of the CPU 265W so thats for those 2 586W allready. Would a 7 or 800W unit be the better option or should the 620W be able to cope?
Right here on your GPU's specs it recommends a 650W PSU. That recommendation is system wide not for the
GPU itself.

And... where do you see that your processor sucks up 265W?
