Cables and connectors

6 of 7 differ

CablesiOne row per kind of cable that runs from the PSU to a device. Connector is the plug at the device end. Count is the number of those plugs over all cables in the row. Length runs from the PSU end to the first plug. Adapters that plug into other cables are left out. Use 16-pin PCIe when the maker names a 16-pin GPU cable without saying 12V-2x6 or 12VHPWR. A cable from a 12V-2x6 socket on the PSU to 8-pin plugs is a cable, not an adapter, and counts as PCIe 8-pin. When the maker's documents name one GPU cable both 12VHPWR and 12V-2x6, use 16-pin PCIe and name both in the source note. Cables of one connector kind with different lengths or wire gauges get one row each.

Inside the Box lists one dual 8-pin cable, one single 6+2-pin cable, two SATA cables and one peripherals cable. The dual 8-pin cable has a 16-pin plug at the PSU end, so it counts as PCIe 8-pin with 2 plugs.

Wire gauges and the 600 W rating of the 12V-2x6 cable come from Cybenetics and the overview text (a 600W 12V-2x6 connector). Cybenetics lists 475 mm and 105 mm for the same cables.
