By the way, you don't "need" a special plug or an outlet to have 220V.
It just have to be connected appropriately.
I have few regular 5-15 and 5-20 outlets connected to have 220V.
Now, you do have to mark them properly, so that you don't plug in your 110V stuff there:)

Eliminates the need to have to buy special PSU power cords and such.
