The difference between the max efficiency and the min efficiency is gonna be like 2%, at most, once you're above 10% load on the PSU. You would not be able to notice the difference on your power bill.
It's hard to get hold a decent mic which uses the 3.5mm jack nowadays. I had this struggle, couldn't find anything decent in stock or they are EOL.
In the end I took the plunge and purchased a "Blue Yeti X" which unfortunately is currently also out of stock but anyway... best decision I made! Everyone i talk to says I sound amazing. It took some time to get used to a desktop mic but I will never go back to crappy headset mics again.
