Does this adapter exist?

[chuckywang]

I want to connect a SATA hard drive to my computer, but my power supply is old and only has peripheral connectors. Is there a peripheral to SATA power adapter?

Yes, you should be able to pick up an adapter at a local B&M.
Called 4pin Molex to SATA power iirc.

...Galvanized

One thing I don't know why...Why can't PCI-e video cards and SATA HDDs simply use the good old 4-pin molex?

The same reason as to why we can't have a standard "plug" for the front panel connectors :disgust:

Actually, there might be an actual reason, I'm not sure.

OP, yes there is.

Interesting...it seems like my mobo (see sig) came with one. I didn't know what it was until now. Thanks all!

For SATA drives, at least, they wanted a lower-profile connector. This can be important for slim 2.5" drives used in laptops.

No idea on why they felt they needed a new connector for PCIe cards. Maybe it's specced for more current than a regular molex connector? But then you wouldn't really be able to convert between them...

THAT's just case and motherboard manufacturers being dumb.
