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.

Not all PSUs even have a second cable. Mine sure doesn't.

Technically it's fine to use daisy chained connectors. People get into trouble though with badly built power supplies, extreme overclocking, or cards like the R9 295X2 that blatantly violate the specifications.

Older PSUs sometimes have trouble with new GPUs. It generally happens because new cards have large power transients that the older spec didn't take into account. Sometimes running a second line fixes this for one reason or another, but not always. 12VHPWR actually uses similar current per wire or per cross section area of wire as a daisy chained setup, if not a little more.
