I was wonder would it cost a lot per month if you ran a computer that was 480watts 24/7 your power bill?
my country maybe different from your,, me like RM30 @ $10 (usd) permonth
Well imagine what's your 32 inch TV eats up in watts in a week and divide it by 50 you'll have your consumption for a month 
Yah, the only thing that might get you is the heat coming off the computer by always running it...
I have noticed you keep the door shut were the computer is it heats the room takes a while but it works.
^ amen to that! when i'm back from lectures.....toasty room 
Way to save on heating oil too. cost less to run a computer then to get more oil filling up your tank have to pay $200-300 or use a computer that cost at the most 5.00 dollars a month.
Here is some info I put in the PSU FAQ.
There are also AC power meters available for around $30 USD to measure how much electricity (AC) a item uses.

Q: How much power does a power supply use (both AC & DC)?
A: If a system consumes 200watts DC, then the power supply will only consume 200watts DC. It does not matter how many watts a PSU is rated for. -->For example if the system consumes 200watts DC but the PSU is rated at 500watts DC, the system will still consume 200watts DC(not 500watts DC).
Maximum DC power output can be affected by the PSU's internal temperature. Most manufacturers rate the maximum DC output at a internal temperature of 25C. This temperature is not a real-world scenario as most PSU internal temperatures are in the range of 35-40C+. As the temperature inside of a PSU increases, the maximum DC output decreases.
Because of the nature of switching PSU's, the amount of DC consumed does not equal the amount of AC consumed. Componnents inside a computer cannot utilize AC for power, so the AC needs to be converted to DC, thus "switching". In the switching process, some of the energy is lost being switched which also correlates to the efficiency of a PSU. Most PSU's have a efficiency rating of around the 70% mark on average. So, if a PSU (with 70% AC to DC efficiency) consumes 200watts DC, then it will consume 285 watts AC.

But one of them is worth 6 months of computer use.
Not worth buying one haha
I was just wondering if left my computer running a lot the power pill would go up $20-$40 dollars but only about $5-10 is not bad.
I run the following rigs 24/7:
P4 - 420W
2 x AMD 3000 - 300W
1 x AMD 3000 - 600W
1 x AMD 2600 - 300W
Now, I know this is totally unscientific, but I figure it costs about $50/mo to let these rigs run 24x7 folding at 100% CPU utilization- and, yeah, my room is more than toasty.
There are lot's of factors on how much it will cost:
Usage
PSU efficiency (as lilkev715 explained above)
Cost per KWH
Here where I live, power is fairly inexpensive at 6.7cents/KWH. The more efficient your PSU, the less it costs (obviously) and the less heat it generates. Using lilkev715's 70% as a normal eficiency rating means 30% of the power consumed is being converted into heat.
For those interested in measuring power consumption, I have found only 3 different consumer-level devices after a fairly exhaustive search I did a while back, and here is where I have seen the cheapest prices(you may be able to find better prices):
Kill A Watt
Seasonic PowerAngel Power Monitor
Watts Up? Power Analyzer
Of course yoy can spend hundreds or even thousands on prfessional grade analyzers.

Thx for the info about the watts I was wondering about how much it would cost 1 computer thats got a amd64 athon +3200 with 480 watt ps.
