Power Cable
(COL) R390-PC
Has four contact connector, center thumbnut. We have discovered this IS NOT the actual R390 cable. The alignment keyway slot is in a different place. This aspect can be modified, if you have the ability. Be advised these cables will not plug into your R390 as-is. To compensate you for this trouble, we have discounted cables by $10 from Catalog 8 to $25.
