* Includes 2 x PCI-E 6/8pin cables with double connections (so up to 4 available) or 2 x PCI-E 6/8pin cables with single connectors for neatness - can use either of these for 2 connections, both for 4 connections, but can't have all 6 at once. Likewise, using the 12VHPWR / PCI-E 5.0 cable uses 2 of the sockets on the power supply, so another PCI-E cable can be used only if one AUX 12v for CPU power is used only.
