just because you have a 700w psu doesn't mean you will be using 700w.
The actual load from the cpu/gpu/hdds etc combined with the efficiency
of the power supply gives you the at the wall consumption.
Most "office" machines will pull ~60-100W depending on cpu vintage and
work load.
gaming machine in full swing 300W+
If you want to save some power get a psu rated for efficiency
80+ bronze is a good place to start.
Also keep in mind that a 700W psu running with 50W load will be quite
inefficient, you could be pulling 100W from the wall and burning 50 just
heating up the psu.
My I3 tv computer pulls ~30-40W with 4HDDs,nvidia 260 gpu and a SSD in
it, up to around 50W with all the drives spinning.
I put that together with some mind toward power consumption but not
going nuts.
My mothers tv computer, dual core atom with 1x 2Tb hdd and onboard 9400M
pulls 28-30W.
I don't know who is saying desktop pc's are pulling 12W but I haven't
seen a system that will pull that from the wall outside a laptop.

In the last few days, I've been reading studies showing that
average power consumption of a PC is about 12W. Which
is not incredibly high.
Makes me wonder how much I’m killing the planet with the 700W power
supply in my PC.
