You might get more coming out of it if you load up the laptop with a lot of USB type devices that need voltage... but then you're running your pc with an extraordinary draw on your power supply, which will make it run hotter than usual.... not good. If you keep it up, you will have to replace your power supply... as it cannot continue to deliver outside what it's rated and manufactured to deliver. The same principle goes for built-in power supplies in a desktop.

Really they're not that smart. Some company should make some that are smarter. That would be a nice change.

That's what I'm saying. If a PS is loaded up because devices are drawing power, too much power from it... in most PSs, there is really no component to control the outflow of amperage being outputted. As I stated, this makes the PS hot... When it runs hot for an extended time, it tends to burn out.

A little off topic (but interesting): You mentioned the battery being charged, and when it's not. I would hope that the battery is not tolerating a constant charge, when it needs a charge or not... but I don't know the internals that well. This is where some intelligence can be put in the PSs of computer systems, if it's not there already.

But will the ram in what ever stage it's in raise the electric bill?
It is understood that the motherboard has power available to be used by the ram in what ever stage it is in.
Will using ram raise you electric bill more that the price of a good greasy cheese burger.
I don't believe the OP wants a scientific electrical engineering answer to his/her question.

The OP's post #1
Also if you have 32gb in your computer but use only 8gb in day to day activities does it still cost more electricity because all 32gb are running?

Girom if you are still there my answer is.
Because you indicate day to day activities I am assuming you are a normal user.
32gbs of ram will probably be more ram than you will ever use but that is okay. More ram than you need only hurts your pocket book when you buy it.
You will not see a jump in your electric bill any more that you would if you forgot to turn off a lamp when you left the house for dinner.

Most power supplies supply a constant output voltage. How much current it will supply is entirely up to the load. No power supply can regulate both voltage and current output into a load it has no control over. Ohms law doesn't allow for that. Most power supplies do limit current output but this would of necessity lower the output voltage, which would soon cause the equipment to malfunction. This current limiting is the only way the power supply can protect itself from destruction by overheating.

Actually, the better PSUs have what are essentially self resetting "circuit breakers" to protect them from overcurrent situations. If the load exceeds the capacity of the PSU, the PSU's internal circuitry will shut the PSU down briefly.

article: Kingston’s HyperX LoVo-series DDR3 memory

Found an article that discusses low-draw / low voltage DDR3 DIMMS made by Kingston Technologies. It seems to be a growing trend to be 'green' when looking for computer components these days. So in this respect, the OP is 'point on'.

Article Link: How Much Power Does Low-Voltage DDR3 Memory Really Save? : LoVo Means Low Voltage

Apparently, these DDR3s save a few pennies off of your electricity bill every month.

Pricespy.com.nz info: Price history for Kingston HyperX LoVo DDR3 PC12800/1600MHz CL9 2x8GB (KHX16LC9K2/16X)
