That's a max rating, if you are running s PSU with high efficiency and low voltage hardware (eg slower CPU/RAM, SSD), then you will be a lot better off than owning a dual GPU, i7 gaming beast. On 18 October 2012 20:51, Jeremy Visser jer...@visser.name wrote: On 18/10/12 10:58, David Lyon wrote:

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
