It's also possible the PSU will operate *worse* if it doesn't get sufficient 
loads on certain rails. I got tripped up once where a 200W flex ATX PSU was 
perfectly ok on a board with an attached hard disk. Removed the disk in order to 
netboot and the thing wouldn't even get past the BIOS check. Had to put the disk 
back :(
