Is there such a thing as a molex connector to a usb (or wall socket) converter?

I tried searching online, but couldnt find anything..

Yes there is. Not to USB, because USB can't provide the necessary current for things like 3.5" hard drives. The only thing a USB can really run is a little laptop hard drive. As for a molex to wall outlet, they include ones in USB to IDE converters:

Or you can make your own (taken from a tutorial on how to make an adapter for cathode lights)

1) I found a wall transformer that was used to power an old router. It was rated at 500mA. And it lights it up bright, no probs. If you were going to be using more lights, then I'd say step up to the 1000mA one, or so. (I'm just guessing here, LOL).

2) Cut the end of the Transformer off (the plug that you connect to device), and leave pretty much the entire length of cord. Split the two wires down the center about 5" from the cut end.

3) Remove the insulation from the wires (only about .75"-1"). Now, you need a Molex connector. Once you get the Molex connector, you'll need to use the Female end of the Molex...So, cut the wires, and remove some insulation off of the Yellow wire, and the Black wire right next to the yellow wire only.

4) Look at your transformer, there should be one completely black wire (Negative wire), and one wire with a gray line, or writing on it, (Positive Wire).

5) Connect the Black wire from the Transformer (Negative), to the Black wire on the Molex connector next to the Yellow wire (See Pic). Cover with electrical tape.

6) Connect the Wire from the Transformer that has a line or writing on it, to your Yellow Wire on the Molex connector (See Pic). Cover with electrical tape.

7) Plug in your Light to the Molex, then plug into the wall. Viola!!!

Your OP is not a model of clarity. If we understood what you were trying to do exactly, we could be more useful. bgmicro sells wall-warts with 5 & 12V outputs but they usually have mini-DIN connectors. Easy to cut off the mini-DIN or buy a matching min-DIN female and make an adapter to Molex or just cut the mini-DIN off and wire the Molex directly - I've done one that way.

USB only supplies 5V and 500mA max current if nothing else is connected. You can use a self-powered hub if your USB device needs more power.
