Hi,
I need a 3rd PCIE cable to power my 3080 Ti FTW3 with a 850 GM SFX in a new build. Can I use PCIE cables from my old 850 G2? And I can plug this 3rd PCIE cable into the 2nd CPU port on the 850 GM SFX correct?

    Yes, you could use the cables from the g2 I believe based on this article...
     
    https://www.evga.com/support/faq/FAQdetails.aspx?faqid=59698
     
    Using the pci-e cable in the cpu port on the psu should not be done. pci-e cables are suppose to be plugged into the vga ports on the psu.
     
    Looks like you'll need to power the 3rd input on the gpu using one cable even though it's not optimal.

    I can confirm it works just fine, I just finished a build in the Lian LI 0-11 Mini! I have a 12900k and 3080 TI FTW 3 with EVGA GM 850, No crashing no blue screening or anything works perfect! 
     
    One thing you should know is that the PSU will coil wine, people have complained on reddit the EVGA SFX power supply's have a coil wine issue underload, coil wine wont hurt your components but can be annoying depending on how sensitive you are too it.
     
    Also the cables are super short, they wouldn't reach to the front of the Mini, I had to buy Cable Mod cables! You will be fine, Enjoy your build!

    Please note that we also have a CPU EPS 8pin to PCIe 8pin (6+2) cable available now that you can use on a spare CPU port:

    Generally, a second 8pin is only needed if you are doing extreme overclocking involving sub-zero cooling.  A single 8pin is fine for even normal overclocking, no matter how powerful the CPU is on a standard desktop motherboard (SR-3 and WS boards are a huge exception).  The only concern using a single 8pin is if you're using a really cheap PSU with a very low gauge wiring on the 8pin and 24pin connectors, as that may cause the cables/connectors to get really warm.
