I have 15x sata 1TB HDDs. I wish to wire up all of them. I had a 350 watt dual 12v rail PSU. I was thinking about using a 24pin dual jumper so when PC comes on the external PSU does. That's easy. My question is this how best to connect 15x Sata cables. Please if possible no need to ask why so many. My answer would be why not.
