  1. Given that you are mostly known for the PSU Wizzard, you should also include the whole system power draw (idle most importantly) with or without dedicated GPU. This is important when choosing PSU based on the given power draw (choosing between PSUs with low load performer or normal load performer).

    1. Whole system power consumption is affected by the PSU and the rest parts I use. Most of you won’t use the same so I believe that providing exclusive CPU power figures is the best.
