Posted December 3, 2020 I have a GTX 1060 and I'm buying an RTX 3070. I need to upgrade my PSU, and I'm looking for my cheapest option. I need 4 6+2 connectors in total. One for the CPU, one for the 1060 and two for the 3070. My PSU has PCIe cables that have one input end and two output ends (like this one). So one 8 pin port on a modular PSU can be hooked up to two 6+2 devices. The PSU that I'm currently looking at (Corsair RM750X) only has three ports for PCIe and CPU, but I want to hook up the 1060 + the 3070 with one cable coming from the PSU, another cable for the 3070's second power port and a third cable to the CPU. Kind of like this: (hopefully the drawing doesn't fall apart after I post it) ┌─────┐ │ │─────> CPU 4+4 │ PSU │─────> RTX 3070 │ │ Î │ │────────┴────> GTX 1060 └─────┘ Is this a good idea or should I look for a PSU with four 8-pin connectors?

I recommend get a new psi with the 8 pin connectors Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

The CPU connector is not interchangeable with the PCI power connectors. Why not connect the single 6+2 pin to the GTX 1060 and the double 6+2 pin to the RTX 3070? Why are you keeping the 1060 in your system in the first place?

Posted December 3, 2020 Well there won’t be any load on the 1060 if you just game right? Assuming the psu can handle that card and cpu it should be fine. Id still get something with some headroom myself.

The RTX 3070 has a power rating of 220W, and I've read somewhere that in most cases the 8-pin cables can only carry 150W. Plus I'm sure there is a reason why the engineers put two separate 6+2's on the RTX card. 3 minutes ago, HairlessMonkeyBoy said: Why are you keeping the 1060 in your system in the first place? After I get the card, I will finally be able to switch to linux. I also have VR, so I will need a Windows 10 VM, and this way I can pass one GPU to the VM while keeping the other one on the host.

So with dual 8 pins, you could pull 375w. I could use some help with this!
