In researching the dual psu power issue i've heard some advocate powering the riser and PCI-E power connector on the card with the same PSU. Others say the psu that powers the motherboard must also power alll the risers. The slave psu should only power the PCI-E power connector on the card. Haven't found a definitive answer but it seems the people having cards die were using the slave psu to power both the risers and the PCI-E power connector on the card.
