When building my mining rigs I went with all EVGA PSUs for compatibility only to then find out that not all of the cables are the same.  I'm looking at PCIe cables and see that I have 2 different styles.  This may have ruined the entire point of sticking with EVGA.  Some have 2 of the pins connected but appear to be the same otherwise.  Is it safe to mix them by using non-connected cables in PSUs that have the connected pins?  
Also, It seems that the CPU ports are the same as the PCIe ports.  If only the other end of the cables are different is is safe to plug PCIe cables into CPU ports on the PSU so that I can power more GPUs?
Are there other cable compatibility issues I should be aware of?  Before realizing that they weren't all the same I put them all together and now have no idea which cables came with which PSUs.  Is this a problem for me now?
I have 220-GA-0850-RX, 120-GP-1000-RX, 220-GA-0850-X1, and 210-GQ-1000-V1.
Final question...   How close to maximum wattage is it safe to run these at long term?  I'm trying to stay at least about 15-20% below maximum.  Is that reasonable for long term constant draw?

    NO, I don't believe the EPS[CPU] ends are pinned the same as the PCIex. The plug-in part should be keyed differently [to the component end] to prevent just this from being done. There are adapters available, but they are very particular. I have also seen many member way smarter than I recommend NOT to use adapters. 
     
    Is the complaint between using a 6+2 PCI ex, versus an 8pin PCIex? If so either should work. 
     
    Also, I am not sure about the compatibility of the GA PSU. It maybe time to call EVGA to get your cable mixture figured out before you have an issue. Most of the individual sleeved cables are compatible through most of the line...BUT, better safe than sorry and have a big problem. It is always recommended to use the cables that came with PSU.

    Good luck! I'm not sure of your last question, I'll leave that up to either another more knowledgeable member or tech support.

    GA and GP share the same cable pinouts.  GQ, however, uses a different SATA/Perif pinout than the other two.  Definitely do not mix cables for those ports.
     
    Likewise, regardless of your PSU, do not mix CPU and PCIe cables.

    Is there a way that I can positively identify which cables went with which PSUs so I can safely separate them. 
    Are the ports themselves compatible on any given CPU so that I could plug PCIe/VGA cables into the CPU ports to power GPUs or risers?

    I wish I could have used all the exact same model but purchase limits forced me to mix models.  I had hoped that by getting all the same brand it would still be compatible even with varied models.  :(

    If you post pictures of the cables, we might be able to identify them by their sleeving.  Most other cables have the PSU unit listed on the side of the connectors.  
     
    The only PSU that you can swap CPU/PCIe cables that way is our G2L power supplies, which unfortunately doesn't help you here.  Otherwise, CPU ports on the PSU side have 4pins ground and 4pins +12V, whereas PCIe has 5pins ground and 3pins +12V.  That's not an equation that will lead to happy results.

    I do have a couple more PSUs currently being shipped to me.  I'll see in a few days if I can ID what I have based on comparing with what is coming.  If I still have any questions after that I'll be back.
    Thanks for the help.

    where are you even finding multiple PSUs? all from same supplier?

    Right here through EVGA.  I've been ordering from their B stock page.  

    I've been ordering 850s and 1000s as they come available.

    I tried sharing a link to their b stock page but it didn't show up.  Apparently they don't allow links even if they lead to their own page.

    rhsou, you can't post links until you hit 10 post I believe. It has to do with trying to stop the spammers that frequent. I hope you get you cables sorted. 
     
    @CLL1990: If you go to the product page of the PSU you want, you can do the auto-notify. EVGA will send an e-mail when it is available. I have just done this on the 1000 G3 PSU. It only took a few days for it to come in stock, and notify.   
     
    I hope you guys are taking advantage of members associate codes to save a few bucks on your purchase. You can find them in peoples sigs. 
    I think it is a 10% discount.

    Ouch.

    Great idea, but the limits and shortages are causing issues.

    Good luck with the IDs.
