I am trying to use a spare power supply as a supplemental power supply. There
is no room in the case for a second power supply so I put it outside the case
and threaded the cables through the back of the computer case then attached
the cables to unattached hard drives. Then, I turned-on the spare, external,
power supple then turned-on the internal power supple but the spare, external
power supple did not turn-on. What should I do?

Not being a technician, I am only responding since no one else
has.

What you are doing makes no sense. First, it is RATHER unlikely
your current power supply is not enough. If it IS NOT enough,
trade them both in for a more powerful one. Doing what you are
describing above is a little crazy, no offense.

AFA you other question, I believe almost everything in the
computers runs on 5V. But as I said, I am not a technician.
 
Re: Suppose I add ..............

Search for ATX power supply *requirements* and *technical data*.

Use AT power supply instead of ATX power supply.
AT power supply has a switch which you can power on it.
You do not need to connect AT power supply to motherboard.
Switching on the power switch of AT power supply is what you need to
do.
Both can supply power to IDE harddisk.

Re: Suppose I add ..............

Your external power supply needs a 'power good' signal to be fed back to it
to tell it to continue running. Look at the detailed specifications for the
particular power supply type you are using and you can work out how to make
a plug for the mainboard connector that can provide the required signal.

Note that what you are attempting is extremely risky and there's a good
chance you will blow something up unless you arrange things correctly.

Re: Suppose I add ..............

In addition to Jeff's excellent advice, not only must the power supplies
receive a "power good" signal, and *must* receive this signal within just
fractions of a seconds within being powered up.

If you are anything but an experiences tech, I wouldn't even attempt to do
what you describe. I'm experienced enough, but not crazy enough, bored
enough,....

Re: Suppose I add ..............

I hope I'm not reading this right - that he is trying to tie the outputs of
two power supplies together, even if they are supposedly the same voltages.
That is a definite NO NO. Even if they were perfectly identical, it
is far too risky. I'm an E.E., and I would *definitely* advise against
this!

Now, if you want to split up the loads and run them off of separate
supplies, that would be different, but that's a pain in the butt, too, and
not really advisable.

Re: Suppose I add ..............

Bill,

I was *afraid, very afraid* to ask!! (Also known as the "shot-heard-the
world) Kinda like piggy-backing two car batteries in parallel for *extra*
current capabilities, Huh?

If the wind is in just the right direction, you can just about smell the
burnt aroma--that's just the more innocuous stuff. Oh, that whithish-power,
that *only* electrolyte.

Re: Suppose I add ..............

Did a second read on you post Bill,

In the fraction of a second it would take for the "power good " signals to
be in virtually perfect sync., can you imagine what start-up waveforms
(clean/dirty/spikey) one would see if doing the first of the two
situations--MUCH less scenario two.

IMHO, if (1) is what Dan' wants to do is get an advanced EE, and STILL have
a lot of time to kill.

Re: Suppose I add ..............

I don't think he's trying to parallel the power supplies, but rather is
using one power supply for mainboard and some of the peripherals and a
second supply for some additional devices.

This can be done, but needs a very careful arrangement, apart from the
problem of providing the power good signal, in order to avoid destroying
something.

I can do that also--just a TAD OT. But I'll be more than
