you can run it at whatever wattage is right for you. at about 800w I'm heating my apartment and getting around 10/TH.

unmodified, noise is a thing. Not as bad if it's downclocked, but still definitely noticeable. think vacuum in the next room over. you can add fans to make it quieter as well.

it can be plugged directly into the wall for most US homes, so that was nice to figure out
