Load on the supply isn't critical, the surge is just getting the power supplies started up before they even start producing an output.

I ran into the problem on a smaller scale on some medical equipment I designed mumble decades ago, I had one switching supply powering another. The startup current of the second one would trip out the first one. I had to devise a soft-start for it. Now most supplies have fold-back current limits on the output, they reduce the voltage to keep the output wattage in check but since they still supply some it lets things get going. Solves most startup problems like I had.
