Hello nephjason,   The cable you have, PN#787PR,  will work with the PERC HBA330 Adapter and the PERC H740P Adapter
We have a PowerEdge 740XD currently with HBA330 pciE card (no raid) wanting to replace with a raid card - probably the H740P Will the same cable work for either card? The cable we have now is part number 0787PR This is our configuration:(asking about cable #6) [IMAGE]  
Replacing HBA330 with H740P, cable needed?
