Question about PSU's

[Mikesta]

Having a high power wattage of a psu like the watt 480 or 500 will cause a increase in monthly power bills right? About how much? Im running around 3 computers in my room by the end of this year one has 300watt,250watt,and 400watt (soon)

The answer is no, unless the consumption of PC is increased. Meaning 300W PSU will spend about the same as 500W PSU, on the same computer, provided that they are both stable.

NO it will not increase your power bills,the computer will continue using only what it needs,nothing more.

having a bigger psu will have more power reserves if you need it but will not increase your power bill.

I would tend to think there to be a slightly higher overhead running a more powerful PS, but would be very surprized if it added up to even $1/month. Get the bigger one, you know what they say, "Better to have it and not need it..."
