Pulling extra power

[Brandenr]

I was wondering if it's possible I make 2 x4 pcie riser card to 4 pin power adapters and use it to give a gtx 1660 with a 6 pin to 8 pin adapter  the power it needs without upgrading the psu on my inspiron. X4 is 25w a piece

While in theory you can, it would be kinda silly and worse than other solutions.

It would be much easier to just  modify your power supply to add a pci-e connector. You wouldn't even need soldering.

 

 

Get a 6 pin / 8 pin pci-e extension cable, or a 2xmolex / 2xsata to pci-e 6+2 cable,  and plug it in a free molex connector (the one for old hard drives)

If you don't have unused connectors, you could just use a sharp knife or blade and strip a bit of insulation off the cables from the power supply and cut the molex/sata connectors from the adapter cable and carefully twist the wires from the cable to the wires that had their insulation removed... then use electrical tape to insulate the wires. Ideally you'd solder for better connection, but just twisting and insulating would work. 

 

The 12v wires are yellow, the ground wires are black ... that's all you need to know.

It would be far easier to just buy a PCIe extension cable, cut the female end off, open the power supply and solder it in. 

Though there's still no guarantee that your power supply will be able to handle outputting the extra power.

I was asking because I was going to see if it was possible on my inspiron to test with. Because I'm wanting to do it to a shuttle xh110g. You cant mod the psu.
