Well I have a 620w seasonic psu M12II-620 and I was wondering does the power consumtion vary according to how much im using or is it always consuming 620w ? I looked at the bills the other day and there is a 3 kw increase on average per day when compared to last year. We have nothing new in the house apart from my new computer, I used to have a dell pentium 4 laptop so im guessing that 3kw increase is me
