I know there exists power calculators for modern parts, to give you an idea what kind of power supply you will need, but is there such a thing for old 'retro' parts?

I'm putting together a build, and I'm wanting to use a Pico psu and 12v power brick combo, so I want to know what's the minimum I can get away with (it gets expensive as you go up in the watts department).

Anyone have a good idea what a P233mmx, 128 mb ram, onboard 2d VGA, voodoo 1, AWE 64 value, compact flash & a slim dvd drive, would require?

So, yeah, could I get away with 120W?

Edit: I found this thread, which has a few nuggets in it: Re: Total power watt of your systems

I'd expect 120W should be more than enough. Until around the P4 computers didn't need all that much power, so if it can deliver enough on 5V. I wouldn't expect the whole PC to use much more than 50 or 60W, half of it coming from the Voodoo and the Pentium MMX.
