Why does the PCIe power adapter have two plugs at the end that plugs into the power supply?

Last Update: 2017/05/10

Most newer power supplies now come with a dedicated 6 pin PCIe power connecter.  If your power supply does not have one, you must an adapter in order to power your graphics card. This will ensure a reliable flow of power to your graphics card and help stability.

All PCIe connectors on your GPU need to be filled or your EVGA graphics card will not power on successfully

Below are some images of the adapters provided with select graphics cards:

2x 4-pin to 6-pin Adapter
2x 6-pin to 8-pin Adapter

These adapters connect to the following PSU cables:

Molex 4-pin
VGA/PCIe 6-pin (or 6+2-pin)

Keep in mind that these adapters are provided as a temporary solution to your issue as a lack of connectors would be considered a compatibility issue. Long terms dependence on adapters is not advised, however when used properly, they can provide flexibility to your system that may not have been possible without them.

Never connect an adapter through another adapter (aka daisy-chaining). This may 'trick' your PSU into operating outside of it's intended specification which can lead to catastrophic failure.
