Provides a wide range of options including free-hanging or panel-mount housings and 18-30 AWG terminals You COULD get a peripherals cable, cut all the wires EXCEPT one 12v wire and one ground wire, and then connect those two wires to a pci-e 6 pin connector, because that 6 pin connector has 3 x 12v wires and 3 x ground wires.The smallest-to-date automotive-grade sealed system in the industry, as well as the only receptacle offering a IP68-equivalent rating adhering to USCAR specifications That's good enough for around 100 watts of power. So if you were to cut the orange and red wires or disconnect them somehow, you may get a single 12v wire and a couple ground wires. Ground with 5v (BAD, direct short between ground and 5v, either psu shut down or melting wires or hurt video card) , You get conflicts : (orange = 3.3v, red = 5v, yellow = 12v, black = ground, white = unused)ġ2v with UNUSED (no connection, not good but not bad) ,ġ2v with 3.3v - BAD, you can damage things, short circuit between 3.3v and 12v - in some scenarios, components that use 3.3v like m.2 ssds could receive 12v instead of 3.3v and blow up So if you plug it into the peripheral on the case : The 6 pin pci-e connector that goes into a video card is the left side of the 8 pin connector in the picture : pay attention at the difference between pci-e 8 pin and and the peripheral 6 pin headers : Here's the most recent pinout of the headers. But you absolutely can not leave wires and ignore the other voltages in the 6 pin peripheral header on the psu You COULD get a peripherals cable, cut all the wires EXCEPT one 12v wire and one ground wire, and then connect those two wires to a pci-e 6 pin connector, because that 6 pin connector has 3 x 12v wires and 3 x ground wires. So when you're inserting that 6 pin pci-e connector into the peripherals header on your power supply, you're basically putting 5v and 3.3v on wires that the video card expects 12v or ground - that's bad, and you create a short circuit which either damages the circuit inside the psu that produces 3.3v or 5v OR will eventually melt the wires OR shuts down the power supply to protect itself OR you damage your video card. The pci-e only has 12v and ground, and must not have any other voltages.

The peripheral 6 pin headers on your power supply have multiple voltages : 3.3v, 5v and 12v and the ground wires for them. PSU Peripheral & SATA > 6 pin PCI-E input > 6 pin PCI-E output connected to the riser. Im not trying to connect it to the GPU, only to a riser. However, even if this does fit, you mean that the wires still arent compatible? So if i understand you correctly, the PCI-E shouldnt even fit in the PSU? They look exactly the same and the 6 pin went in perfectly (see image, it has no electricity). that's because both have only 12v and ground wires, just arranged differently.so the header on the psu side can be the same. What may be interchangeable is the EPS (cable with cpu 8 or 4+4 connectors) and the pci-e cables. The headers on the psu should be keyed differently, so you shouldn't be able to accidentally or intentionally plug the cables in the wrong locations. You will potentially damage the pins in the connectors and if lucky you'll just have the psu shut down - if you're not lucky components inside the psu could be damaged.

So if you somehow manage to plug the pci-e modular cable into the peripheral header on your power supply, when you plug the pci-e connector into your video card, you'll most likely create short circuits between 3.3v or 5v and 12v or the ground wires. The connectors for peripherals have 3.3v and 5v wires besides the 12v and ground wires. The connectors for pci-e have only 12v and ground wires.
