Jim:

In terms of just delivering power to the device (power supply, in your case)
you only need two wires, the black (hot) and white (neutral). I believe they
still sell 2 wire outlets for existing runs where it's downright impossible
to add the third wire. However, both building codes and safety would demand
that you add the third ground (green) wire. Hopefully, you're in a location
where adding a third wire will not be that difficult. (And, if that's the
case, you might want to consider just rewiring everything with at least #12
romex type cable). Personally, I'd rely more on getting the green wire back
to the fuse box and connecting it to the neutral/ground buss bar. From
there, you should have a connection to either a water pipe (be sure to put a
bypass wire around the meter) or to a good earth ground.

If the power supply has a nice package with switch and fuses, you can
probably buy one of those 'cheater' plugs that expect you to tie the ground
to the outlet box, with the expectation that the box is grounded (many are
not).

I live in an old house. And the last time I changed a burnt outlet,
it was not grounded(only had 2 wires...black and white)
So if I want to use this supply I need to drive me a grounding rod
and run the "G" terminal off of that and hook up the other two Wht
to Wht.........Blk to Blk. Right?
Is the grounded green wire to grounding rod really necessary?
Will not using this "G" terminal hinder the performance of the PS or
cause it to malfunction?(ie. just using L and N to power the supply)
I realize that I probably sound like an idiot , but I payed good
money for this used Power supply, and I do not want to burn it up
before I even get to use it throwing some chips!
