Hey

I was wondering, does a, for example 750 watt power supply actually use 750 watts or can it use up to 750 watts.
 
Solution
no,only what your pc needs will consume on your electricity,for example you have a 1000w psu and your pc needs 200w, only 200 watts will consume on your electricity minus the efficiency %

so only 200 watts would go into the power bill?
