Is the usual disk/CD power connector 4pin or 5? Sorry, do not have this at
sightseeing distance, only remember that it has +-5V and +-12V (and maybe
ground too?)


+5-GND-GND-+12, i.e. 4 pins.

SATA requires also 3.3V,

Bull****, as always from the babblebot.
There is no such requirement.

but most drives do not actually need it at the moment.

Because it's usually generated from the 5V internally.
Drives that don't use 5V will obviously have a problem if it is used with a
PS that doesn't supply 3.3 V at the Sata Power connector or are used with
a SATA to Molex converter cable.
