Full power rated up toiThe ambient temperature up to which the maker rates full continuous power, such as 50 °C. A review table that prints 0-50 °C with no maker source is not enough.

Cables and connectors

5 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.

All lengths have a tolerance of 10 mm, the PATA cable 25 mm. PATA plugs are the 4-pin Molex plugs. The 12V-2x6 to dual 8-pin cable counts as PCIe 8-pin, so there are 4 PCIe 8-pin plugs on 3 cables. It starts at the 12V-2x6 socket of the PSU, so it shares that socket with the 12V-2x6 cable.

The 16-26AWG range of the 12V-2x6 cable includes the thin sideband wires, so the stored gauge is the 16AWG power wire. Hardware Busters says the PSU has one 12V-2x6 socket and the second 12V-2x6 cable ends in two 8-pin plugs, which matches the 650+100 mm PCIe cable. That cable shares the socket and cannot be used together with the native 12V-2x6 cable.
