Scuse me?  Our Dell PE1850s come with (dual-capable) 550W power supplies, yes, 
but in our configuration, a Dell engineer used a Dell configuration tool to 
calculate that the maximum POSSIBLE power dissipation was 361W.  The 
implication was that typical max power dissipation would be a fair bit below 

dual 3.2GHz Xeon EM64T
3GB RAM (6x512)
1x 36GB 10kRPM SCSI disk
Myrinet card
