I have one of the older hard drive enclosures and I'm not sure what you call the power plug.
It looks like a serial cable instead of just a circle/hole prong like the new ones all are.
It's an xmedia hd enclosure for 3.5" HDDs SATA. Here the pictures of what the power supply and plug looks like.
My current one is making a loud ticking noise and seems like something is not right so I don't want to risk damaging my HDD if the power supply is suspect. I'd rather just buy a new power supply.
If anyone can help me find where I can order this part or what it's even called, would be great thanks.
