For our latest big procurement I measured (among other things) the actual 
power draw of all final candidates. One was a dual Opteron 2220 (2.8 GHz dual 
core part) which at idle/load scored 218W/301W this with 12 dims (24 gig) one 
sata drive and no IB.

A 2nd vendor measured 230/315 for a very similar configuration.

We did not test any intel 51xx, only 53xx (quad core). The 2.33 GHz 53xx (80W 
tdp if I remember correctly) did around 260W/350W (this with one drive and 8 
fbdimms with a total of 32 gig).

An IB board is typically <10W, Mellanox says that their LX single port DDR 
card is only 4W.

Hope that helps a bit,
 Peter
