Hard drive accidentally powered by PCI-E lane

[sgthighway]

I recently got two Seagate 2TB drives for my system, already home to three other drives. Because my case is getting a little cramped, I installed the two drives on SATA modular power cable that I accidentally slipped into a PCI power lane on the PSU ( I couldnt see) Booted once, drives weren't detected, fooled around with SATA configs etc etc, still nothing, not in Windows or BIOS. Is it possible that plugging it into the PCI 6 pin slot fried both the drives?

Might have.
I have difficulty understanding what you did, but if you fed a 5/3 volt circuit with 12 volt power, chances are you fried something.

On the power supply itself, the SATA/auxiliary female slots are six pins.... so are the ones marked for PCI accessories (ie graphics cards) AND these six pins are keyed the same.... so one can plug a hard drive into the PSU where a graphics card is meant to go.

Are the SATA 6 pin slots 5v and the PCI ones 12?

Yes, SATA has 3.3,5, and 12v lines.
The PCIe power connector is all 12v lines.
Prolly blew the hard drive.

Thanks! Returning the drives I guess
