hell it takes as much as an old boombox or portable tv.
if your talking pc I blew most of what was left in my savings(I do have some other savings but it's in cash and really should be in the bank where it'd do me more good) on a new microwave, which I did need mine was really old and was rusting out on the inside. so I don't have anything to spend on one unless my gofundme succeeds.
lucky. what brand and kind are you using?
