Hamilton police may have solved a murder by posting surveillance tape footage to YouTube. 22-year-old Ryan Miller was stabbed to death at a hip-hop concert on November 17th. Hoping to reach the teenager and early 20-year-old demographic, police posted up surveillance footage of security guards searching concert goers. The one-minute video apparently spooked the suspect so much that he turned himself in yesterday. Read more

Lets take this for example, i have a computer that im using along with a webcam to criate a time lapse video, for that i'll need that have it turned on for about 4 months with no reboots whatsoever (offtopic: its taking 1 picture each 20 minutes for a whole period of 4 months, in order to get a 5 minutes video when compiled @ 30fps\s)

To accurately determine watts used, you need a watt meter. Your PSU rating is not power used. My system has a 500 watt PSU, but idles at about 150Watts or so. Assuming your machine really did use 125 watts, that would be per hour, so it would go like this: 125 Watts *24hrs per day = 3000 Watts used per day or 3KWhr You may want to verify your rate is 0.90€ and not 0.09€ If your rate is 0.09€ instead your calculation would be: If your system actually only uses half that, your cost would be half. I hope this helps. John Message edited by johngoodwin on 08-24-2007 at 02:51:29 PM |

John is right 0.90€ is too high. Here in CT, US its $0.12 and its the highest in the country. To get accurate watt reading i would suggest looking at something like Kill-a-watt. it will tell you how many KWhr you have used at the end of each week, day, hour, minute, and second. I have one and its great. |

You also have to be careful about how they charge the electricity costs.

Buy a power meter. Maplin (UK) sell one that also measures power used.

I know this is just semantics, but none of you are considering the efficiency rating of his power supply at the given load. For instance: most PSU's are rated for efficiency at peak load. Meaning that if you have a 1000W PSU at 80% efficiency (one of the higher ones), then you are actually drawing 1250W off the breaker. (HOLY SHIITE!!!) Now, the efficiency can actually be higher or lower at lower loads, just depends on the quality of the PSU. Then again, who actually draws 1000W of power at load? No one with a desktop that I know of unless they're running 4x crossfire with 2900xt's. Those PSU's are just overkill or for bragging rights or to measure your e-pen.

If you are concerned about the money you would be "wasting" by having the PC running 24/7 (like mine do), don't forget that the "waste heat" from the PC is dumped out into your room air. This has the effect of heating the room that the computer is in, which slightly reduces the load on your home heating system. So, you get to use your computer for fun things, and it even keeps your room nice & warm for you - what a deal!
