30GB 1.8" IDE, 160GB 2.5" SATA and a 3.5" 180GB HDD and I want to power them all from the SAME power supply, how?
I am not looking for how to build the enclosure because that part isn't electrical (an area of expertise where I'm lacking), just how do I power them all because I am fairly certain that the USB port is not strong enough on it's own. Thanks all!

frollard is right. Also, without getting too electrical, if this is going to be a semi-permanent setup you could easily change out your power supply for a higher wattage PSU to give you all the juice you need!

this is what I'm talking about, but how do I go about this, I have a laptop so I still want to connect the drives via USB but 1 main power supply for the 3 HDD.
Hmm, swapping a PSU in a desktop is no biggie, in a laptop things get a bit more complicated, and expensive. I'm sure there's a way to add additional power to the units while they are plugged in, but why bother? I think what you are describing is a very unique scenario with no easy answer. You must have a specific application to want to try this setup. The significant reduction in power is obviously a tell-tale sign that you are pushing the boundaries of your laptop.
Why not compile all the data into just one drive? Just swap out drives so there is only ever 2 plugged in and simply transfer what you need over.
Alternatively, you might be better off just running a garbage desktop for all the drives and just connect to it over LAN. This gives a clean enclosure and satisfies the semi-permanent criteria.
Hope that helps, good luck!

Thanks for the response, basically the idea is that I have 3 HDD's laying around that I want to back up my movies on. I want to hook them all up to a single USB hub and wanted to know how I can power them all from 1 cord as well. This is basically cord management more than power management because I am going to be building an enclosure that has the USB hub inside it and I just wanted to see how I can get it so that only 2 cords come out of the enclosure, USB and power.
So my question is, how do I make it so that if I bought something like this:
http://cgi.ebay.com/2-Port-USB-AC-Power-Supply-Adapter-Charger-US-Universal_W0QQitemZ200350786482QQcmdZViewItemQQptZAU_Electronics_Batteries_Chargers?hash=item2ea5d663b2&_trksid=p3286.c0.m14&_trkparms=65:15|66:2|39:1|240:1318|301:0|293:1|294:50
How do I make a cord that can combine this device (above) as well as my external 3.5" which is on it's own power supply

I think I understand what you are describing.
I still think your best bet it to eliminate the multiple HDD and just compile all information on one device. I hope this helps some. Good luck!
I think I understand what you are describing.
- They sell usb squids which will eliminate the usb cables down to just one.
- Combine that with a power bar.
- Toss this all into an enclosure, bucket or whatever and you're set!

the 1.8 inch and the 2.5 inch can be run off usb power - a 3.5inch drive needs its own power supply. Your usb>1.8"ide adapter or sata adapter should supply the power fine for the small ones.
