I saw this picture while looking at overclocking guides and I wondered if I may have my power setup incorrectly. My GPU is currently connected exactly like the don't do this diagram.

If the GPU has two power inputs, you don't do the “don’t do” diagram. Period.
Like other commenters have input, there are specific situations where you’re probably fine.
If you have to ask, just fix your wiring to one of the green check configs.
This is literally how house fires start.
This is straight up wrong. There are people here who have done that maths for you, if you look hard enough.
This diagram was probably created by a specific PSU builder and intended to illustrate their recommendations for their PSUs, not as a general rule.
Only if you buy a shitty PSU. Quality ones have lots of protection circuits so worst case the PC would randomly shut down in high load situations.
Even then if the manufacturer put two connectors on the end of the cable they made sure to put large enough conductors to handle at least the max load of the connectors specifications. Again if it's not a shitty no name brand. Probably with a good safety factor as well.
It's not like 300-400W is that much energy in the grand scheme of things, so thicker wires wouldn't even be expensive.
Crap I was hoping someone wouldn't say this. Rewiring its going to be a mission.
Yeah this person you are replying to is wrong. Using two lines where possible is a best practice, but in most cases isn't necessary at all. This diagram was created by a specific PSU manufacturer I think, and should only pertain to their PSUs.
For what its worth, I've ran 1 cable to my RX 6800 from a seasonic power supply for years without issues
