Do what I started doing to my mom, just hand her $1 every time she starts in on it, and tell her that should cover today, and then some. I bet your computer draws less than 300w even at full load. My machine draws about that full load, and yours doesn’t have as power hungry of a CPU. That powersupply is a POS though, so it might be pretty inefficient. I think you don’t have it loaded down hard enough to make it’s efficiency drop though. I had this same arguement with my mom, she kept complaining about the electric bill, but she could run her stupid electric heater that draws a kilowatt!!! If you have a CRT, it will draw a little more than double what the same size LCD does. An LCD actually saves a LOT of power. Idle, your puter probably doesn’r draw much, maybe 1.5a @ the most + accesories. Doing a defrag, it might draw 2a, downloading stuff will be close to idle. As long as you have it set to turn the monitor off, it shouldn’t be an issue. Really, it probably eats less than $.50 a day (24 hours), if that, unless you have it running full load all the time. It does add up, I actually bought a seasonic power angel to settle this arguement with my mom. She kept telling me there’s no way her leaving the oven on (electric oven), running the 1kw (actually 1250w) heater, and running the furace/air conditioning when the house is only a couple degrees off didn’t run the bill up!!! Trying to explain that to her was like talking to a brick, she blamed it all on my computer. So, I bought the power angel, and showed her EXACTLY how much my puter consumes. It was a HELLUVA lot less than her heater, or anything else for that matter! She still wouldn’t shut up, even though she knew what was responsible for the big bills. So, I handed her $1, and said that should cover it for the night. She got P!$$3D, and threw it back at me (like she usually does). I even offered to measure the average power consumption of my whole desk for a couple months, and pay that much extra into the electric bill. She just gor more P!$$3D, and told me to shut up, because it MIGHT work out to be $15-$20/month!!! I wish she’d just drop it, it’s OBNOXIOUS, and it’s not like it’s justified. I could see if I had some phase change cooler eating 10a with a big old compressor in it. Or 500w worth of peltiers, or some sort of extremely wasteful cooling on it. It’s just a plain old air cooled computer, and doesn’t even stay on all day. It is on about 16 hours per day though, so it does add up. It’s about the same ammount of power as her kitchen lights that she leaves on all night. God forbid I point out how much power she uses, she just starts yelling! I dunno why women think that computers use so much power, and their stuff doesn’t use anything. It’s pretty much a universal thing, they can bitch about your computer, but don’t SAY A WORD about the hair dryer. Or how about the oven she turned on to heat up a roll (ONE STINKING ROLL!!!), and left on for 3 hours because she forgot. Or the lights she left on in the garage, because she though she heard something. I dunno, not much you can do but try to point out the math involved (good luck with that). The computer will ALWAYS magically eat all the wasted electricity that shows up on the bill!
