So what exactly does this mean? Please be very specific
from now on. Does it mean the same drive is always detected
and the other isn't? Does it mean sometimes both are
detected but usually not? Does it mean sometimes one drive
and other times only the other drive is detected? Does it
matter if you switch the cables so each drive is connected
to the other SATA port?

Ok, but it shouldn't matter. Assuming you boot windows (?),
does Device Manager show the SATA ports and/or the connected
drives?
Try enabling the full diagnostics/tests/check memory, etc,
the bios settings to do the full POST-time testing instead
of only a quick boot mode, _then_ see if giving the system
this extra time allows the drives to be consistently
detected. Also try unplugging one drive and seeing if the
other is detected, and vice-versa, and then swapping cables
around and motheboard ports the cables are plugged into.
Keep swapping around different combination of drive, cable
and motherboard port. See if any combination always works
or always fails. Reduce variables like this and if nothing
else works, try the drives on another system and see if the
motherboard has a bios update addressing drive issues.

It's certainly possible an overwhelmed PSU can cause drives
to fail to spin up or otherwise malfunction, but there was
one PATA HDD, one PATA CD, and two SATA "drives", meaning at
most there are 3 HDDs which isn't all that much of a load,
plus if we understand the situation right it seems only the
drives on SATA ports are effected, suggesting it could be
more likely which ports are used or the mechanical
connections.
If the PSU is of insufficient capacity I would think it
similarly overextended even if there were only one HDD, in
that it will not last long term running at such a peak load.
Checking the voltage, 12V rise-time during system power on
is certainly one thing to do (with a multimeter, there's no
way to effectively get into a bios menu in time to see
that), but otherwise I would check the bios menu for the
SATA drive settings, check the drives with the corresponding
manufacturer's utilities, and unplug/inspect/replug the data
and power cables.
