Hi,
since my PC is always turned on, i have become quite conscious of my electricity bill and trying to keep costs down, especially with the ever increasing rise in bills in the UK (eg. i have gone for a TFT monitor now as they are cheaper to run than a CRT..)
anyway, my question is to do with PSU's. If i use a 300w power supply unit as opposed to a 600w one (and let's say my computer is just idle doing nothing but switched on), from a money point of view, is it actually costing me more in electricity to run the 600w power supply. or does it make no difference which PSU i use but instead it's all to do with how much power the PC components/drives are drawing from the PSU?
in fact on the subject.. if a PSU is rated at let's say 300w, and let's say a normal household lightbulb is 60w.. in money terms is my PC using as much power as 5 lightbulbs then?
thanks
