I've just ordered 65 Optiplex 755 small form factor PCs. They are to replace the same number of SX280s (SFF).

 

These PCs are on 24/7/365, although the task they do is low power (but they mustn't hibernate/go into standby etc).

 

The environment is important in our purchasing decisions, and I wanted to be able to select a PC that is the lowest power consumption. Dell's site didn't seem to provide any help at all in making this decision. I tried HP and neither did theirs.

 

Can anyone help me calculate what power saving (or growth!) I've made by swapping 65 SX280s with 755 (SFF) that are on 24/7/365, generally low processor activity (but not hibernate/standby)?

 

Many thanks
