I was just thinking if you are on your computer anyway would it just use some of the excess electricity that your computer would have wasted or would it be worse than charging your phone from a charger while using your laptop separately.

    This would only affect the 12V rail though no? It’s not like they are beefing up the 5V rail that supplies your USB ports in excessive amounts. Picking a random PSU from pcpartpicker, the CORSAIR RM650e vs RM1200e (650W vs 1200W) both have a +5V@20A rail. There would be no need to have a larger 5V rail to support gaming cards.

    Also correct me if I am wrong, most PSU’s are more efficient at 20-50% utilization, not 100%. I’m basing this off the higher ratings for 80 Plus.
