Hello, What motherboard? Usually, most boards recommend, for 850W and above, ensure to connect both 8pin and 4 pin power plugs or 2 8pin power plugs or above (more) to ensure system stability under heavy loading.
Thanks. I'll just plug them all in other than the one needed for multiple graphics cards.
You talking about the EZ plug thats a molex at the bottom? I plug that in too. Its not for the GPUs but everything else on the PCIE slots that draw their power directly from the PCIE. I have two Intel Optane AIC drives in there so I use it. Whats One more molex connector. Like I said I literally plug in EVERYTHING!! At least that way I know I wont be chasing an issue thats really due to lack of power delivery.
Yeah, I shouldn't need the molex connector.
For the 6 pin motherboard connector, EATX12V_3 in the manual, is a PCI-E 6 pin the right cable?
