higher watts = more $ on your electric bill?

been wondering about this since i saw my electric bills go up...
i have a 550w psu, does it means it will use more electric than my previous 420w psu?

also i have a crt monitor that probably eats alot of electric, thinking to buy an lcd soon.

my mom doesnt even allow lan parties in my house bc she fear the electric bill will skyrocket.
 
It will only eat as much as the system consumes. If its the same system, it wont eat more.
 
No. Your computer only draws the amount of power it needs at any given time. If it needs, say, 200 watts to run at idle, then even on a kilowatt PSU it will only draw 200 watts of power at idle.
 
thats 99% true...
if your rig comsumes say 200 watts at idle
and you powersupply has an efficiensy rating of 70 at THAT (it varries from watts to watts) wattage, then you will use 285 watts AC and convert them to 200 watts DC

285x.7=200

.7 = 70% efficiency

lets just say Seasonic all the way... shall we?

hehe PC Power & Cooling for me, 75% Efficiency and 5 year warranty, had my 510 ATX for about 6 years now, still running strong in probably the 5th or 6th system its been in :D
 
If you want to cut your electricity bills start looking around for warm power bricks and unplug them. Computers are typically no worse than leaving the lights on in your house. Anything that's producing heat is what you want to watch out for.

No, not yet. Look at the table at the very bottom of the link.

that looks more correct, i was curious why they would only rate their PSU's at 75-78% eff, and then test higher :p

PC P&C have been at 75% until their newer models, which are now at 85% :D
