Why aren't all modular power supply cables standardized?

This wasn't an issue for me, but my buddy had recently bought an EVGA Power Supply (750 G2) and had his old Sata Power Cables still connected to his HDDs. Although they have the same 6-pin connector, the layout of the wires are different between EVGA and Corsair (his old PSU). So it bricked his HDDs. (I'm not tracking if any other components were harmed.)
 
My question is, why isn't power cables/psu connectors standardized? This seems like a HUGE issue for someone who has never don't a computer build before, and a buddy gave him some power cables and they aren't compatible. This is especially concerning, considering all these proprietary cables look IDENTICAL. I know for some manufacturers, they have a label printed on their cables stating what PSU they're compatible with, but I think this is completely unnecessary, just make all the cables the same?

    I have been wondering the same thing. It's incredibly stupid that they are not. Everything else pretty much is.

    Maybe if the connectors were substantially different from each other, but they aren't. I was so sure that companies wouldn't try to intentionally differ from each other in this regard, but they don't. I was totally shocked, especially since they look IDENTICAL! lol

    The PSU  outputs (pinouts) are where the differences are
     
    MFG continue to make power supplies that have different positions for the different voltages and grounds on their pinouts
     
    The cables correct /adapt the PSU pinout to fit the Standards used on the hardware end of the cables
     
     
    I am willing to bet that mfg all use the standard modular plugs for their PSU outputs for the economy of standard parts - that is why they fit even if they are not wired correctly for the PSU.
     
    Always Only use the wires that came with your PSU ----> or confirm they are compatible FIRST

    I know, I agree, I do the same thing. I'm just worried about the people who have never built a computer before. As far as they are concerned the 6-pin/8-pin connectors all look the same. I just don't understand why MFG cannot come to some standardization to help consumers. 
     
    The thing about building computers nowadays is that they are essentially plug and play, this defeats that notion by saying that the same plugs aren't the same, and they aren't that distinguishable in nature (to someone who is new). 
     
    Idk, seems rather stupid to me. That's all.

    Hmmm. 
     
    I got that same PSU but used the new cables instead of anything old. 
    Didn't knew about the compatibility part though!

    That is a nasty trap to fall into

    While the cable connectors are almost identical, the internal wiring within the power supplies are not. Some cables from PSU brands even have resistors inside of the cables to reduce noise to the components.

    Right, I understand. Just seems odd that they would do that, that's all.

    would make alot of sense to have them standardised and it would make swapping out psu's a hell of alot easier if need be lol

    Just had to do a RMA on a PSU and it would have been nice if just the main PSU was needed.
    MonkJayn, Are you using any aftermarket cables such as cablemod? I was thinking of replacing the cables once I get a 1080ti.

    Not yet, i keep looking at all the different options, full sets, extensions and brands, right now i have a g2 850, and i think, it'll just about be ok for the 2 ti's i have ordered, but i know it won't be up to the job of my next upgrade to skylake x, more ram and watercooling, so I'm holding off on buying any cables until i am set on the PSU I'll be running, I'm just gutted a couldn't get one of the anniversary Corsair white 1000w ones, would of made life easier.
    Right now though, a full set from evga along with a 1200w g2 PSU is looking to be the front runner option (i keep seeing people with issues with the g3's while my g2 has worked perfectly this whole time)

    If I had to guess I would most definitely say that it's so you buy whatever manufacturers product. Like Apple and their stupid idiotic USB adapters, why not use industry standard USB connections? So you have to buy their product with a markup of 200% or whatever over what it takes to manufacture and warehouse that particular product. Or Dell and HP power adapters for laptops.
     
    A PC power supply outputs very specific voltages, why do the connectors have to be pinned differently? Because they want to be different so you have to buy their proprietary product. I don't like paying $300 for a premium product only to have it cause compatibility issues. Maybe I'm just ranting, but I would expect a certain amount of latitude from manufacturers that produce products for industry standard components.

    The problem is Corsair has failed to meet the EVGA standard for power supply cables.
    Really it would be great but the problem is someone would want to make money off the standard. It's always best I feel to replace the cables otherwise you can bet that some company would want a nickel for every cable using the standard which gets passed onto the end user.
