My EZ-plug 1 was a four-pin std Molex. But the manual shows a six-pin. How many pins is yours? Yes you can use the adapter to the molex (molex is straight one-row four pin, like old computer power plugs). You don't need to use both EZ-plugs unless you are using multiple high-current video cards. The PCIe plugs that come W/AX1200 will work for the six-pin plugs. These EZ-Plugs are actually for PCIe cards.
What video cards are you using, and how many?
EDIT 10/6: I just noticed that I was talking about the R3E, and he (and I too) has the RIVE. FYI.
