Apple has claimed that it continues to use Lightning because replacing it would supposedly produce "an unprecedented amount of electronic waste". [28] [29] Some reviewers, like Business Insider senior tech correspondent Lisa Eadicicco, have suggested that it is simply because Apple wants to continue profiting from its proprietary chargers and accessories. [30] [ failed verification] Problems [ edit ] MFi certification [ edit ] The 6 pin PCIe power connector comes in a 6.25A (75W) version and a 12.5A (150W) version. The 6.25A version only requires that two 12V power connections be present, and only two ground connections need to carry current. The 3rd middle ground connection can be used to sense that the connection is plugged in. The 12.5A version uses 3 12V power wires and 3 ground wires to carry current. An additional two groundable sense connections can be added to the side to tell the PCIe device that a 12.5A compliant power connector has been inserted. Many power supplies that are 12.5A compliant have an additional 2 pin ground connector on the side of the 6 pin connector that can be used to make it to an 8 pin connector.

There are often compatibility issues when building a PC, and power connectors are no different. Fortunately, computers are made by engineers who like to modify hardware that isn’t suited to their needs by default.

You can have 2 x molex -> pci-e 8pin ... each molex has only one 12v wire, and each molex is rated for 5A of current, so in theory your adapter would be good for 2 wires x 5A x 12v = 120 watts. The 6-pin graphics connector is usually common in lower and mid-range graphics units. As the name says, the connectors have six-pin connecting slots with a 4.2 mm pitch. These GPU connectors can directly draw up to 75 watts from an external power source. The power even comes bypassing the motherboard. Six-pin GPU connectors are suitable when a graphics card demands a minimum of 150 watts of power. 6-Pin GPU CableSeveral CPUs come with multiple numbers of PCIe x16 slots. This enables users to harness more GPUs to the system. However, it eventually increases the power consumption of the whole system. A 6-pin power connector can supply 75 Watt to the graphics card. So if your graphics card power consumption is more than 75W then it will have one 6-pin PCI-E power connector for its working. A graphics card with one 6-pin power connector can have a maximum power consumption of 150 Watt as it will get 75W from the PCI Express x16 slot and 75W from the 6-pin connector. Most of the mid-range graphics cards from both Nvidia and AMD come with the 6-pin power connector. I think on modern power supplies the 6 pin can do more than 75 watts. The spec was before 2007 for 6 pin = 75 watts as they only had 2 hot wires.
