I've been tearing my hair out trying to figure out why my second power supply won't run 2 of my cards (750 + 400 PSU's).  I finally found this link:

All working flawlessly now.  5x5830 without needing a $200 power supply.  Grin

You need to properly ground the second psu or it will ruin your motherboard.
