Hey guys. I just purchased a 700watt PSU (Thermaltake W0106RU). Now thats alot of power, and I rarely ever turn off my PC. Mainly because I like using the 5.1 system as my alarm clock because I'm a heavy sleeper :lol:. The problem is I'm affraid of what the electricity bill is going to be leaving this on all the time. So I'm going to be having my computer in stand by or hibernate mode alot more. I was just wondering how much electricity is actually being used in stand by? Is it significantly worth it? Should I just learn to turn my PC off and buy 4 more alarm clocks so I might wake up in time?

I don't have the answers. Not only that, but it varies from PC to PC. So we will need to know your Processor, motherboard, video card, etc... (or computer Make, and model #).

Your PC shouldn't be using 700 watts all of the time, that is just its peak performance. It really shouldn't use more electricity than before, unless your PC was underpowered.

I can tell you this. If your really worried about it, then just set your PC to turn itself on by itself, and then set your alarm program to load at boot (or a music file...).

That is what I do.

As far as I'm aware a PC will only draw as much power as it needs, regardless of the wattage of the PSU, so if all you've done is upgrade the PSU then the answer should be the same as before (give or take).

What ^he^ said. ;)

It's even possible that your new psu is more efficient than your old one, and that you may actually be using less power, albeit a very small amount. Either way, if your pc & habits remain the same, you should see no discernible difference on your power bill.

Quite correct. There are benifits to leaving a PSU on too. Electronic devices hate being switched on and off. (the surge currents you see). But at the same time your PC is more liable to get hotter, reducing the life of all those electrolytic capacitors. The secret is, on and cold. But the really sensible option would be buy a louder alarm clock. The use of a PC as an alarm clock is stupid, never mind the waste of electricity and global warming.

For the sake of reference, I know someone who has a Pentium 955 Exteme-based system with a pair of 7900GTX video cards running in SLI, with watercooling (think pump.)

Under full load, his system draws less than 500W.

So not only is your 700W PSU overkill (how much did you spend?) but it's also not going to represent much of a change in overall comsumption. Draw will increase if it's less efficient, though.
