I am planning on powering the Pico from a computer's PSU molex 5v line. I cannot find any consistent info on the Amps that come from it. Point being, I need to figure out the right resistor to use on that line. Has anyone done this before? @gfwilliams, any thoughts?

I'm not sure you need a resistor? Espruino should run off 5v without needing anything in-line?

Alrighty, was just making sure I won't blow it up. I supposed it will draw as much amperage as it needs as long as that line can supply it

It'll be fine, as long as you don't wire it up backwards or anything :) It should only draw max ~30mA, and usually less if it's entered sleep mode.
