I found a pretty picture over at Start up Power Draw - 45 Drives Technical Information Wiki that I found illuminating.

Fractal, that's a great link. I'll have to find the time to read it. Here is a diagram I got straight from Western Digital some years ago.

Got the SS-660XP2 today and my server seems happy now.
Boots fine with 18 disks attached.
Currently scrubbing 16 disks at ~.77A@235V (incl. xeon d 1537 + ram + 6 fans).
So far no problems.
This PSU should be enough for a few more disks now, I guess.

Thank you very much for everyone's opinions. Much appreciated.

That's a great, well-reviewed PSU. Got mine for $80 AR from Newegg back in 2014. Zero problems with it.

Seasonic Platinum 660XP 660W Review

... Go on. Pick up the nearest dictionary and look up "rock solid." Did you see a picture of this unit next to the entry? You should have, because once again Seasonic is just killing it for voltage stability. 0% regulation on both minor rails. Wow. And look what it takes to get those rails to even move a little bit... you need to throw the whole 125 watts of combined maximum on those two rails to do that. ...
