Cheap = not so fast, e.g. barely four digit speeds or even down to only 700MB/s. I
haven't spent any meaningful time trying to minimize startup bloat either.

Nothing much. HDDs run on 12V, while 2.5" SSDs run on 5V. NVME is less clear to me
so far. My last NVME 1.3 purchase reported using 3.3V, but I've seen the web
suggest NVME can or does use both 3.3V and 12V. So, make sure to read the PS label
to make sure the 3.3V & 5V supplies are suited to needs, while 12V not so much.
Overall maximum advertised power can be misleading. It's possible to need more
total advertised power simply to have enough watts at 3.3V & 5V.
