    Jag har skrivit vad jag rekommenderar.

    Nej, ATX-standarden säger att 3,3V får variera med +-5%, om jag minns rätt. 3,135-3,465V dvs.
    Du måste ha en spänning från nätaggregatet som alltid är några hundra mV högre än LED:ens framspänning för att kunna få tillförlitlig strömbegränsning med en resistor.
