The other way round would be *HORRIBLE*. I use the card in a server and I know 
that on the primary side the power consumption goes up by 6 ... 8 Watts if 
the card is installed. In other words: the card costs me 10 Euro for 
electricity per year!

I measured this because the KNC-1 caused problems with two of my barebone 
systems (Asus/Sis651/P4 120 Watt Power Supply). These machines did not boot 
reliably with the KNC-1 card (the boot process did not even start in these 
cases).

CAN WE TURN OFF FRONTEND POWER to reduce the power consumption? In my case 
unloading the drivers does not reduce the power consumption of the server.

Your Jürgen
