Hello :)

I am installing two additional SATA hard drives to a machine that currently has two SATA drives already installed.

The only available power off of the power supply are two old style 4 pin molex connectors. The wire colors are Red, Orange, Yellow, and Black

The SATA power connector has the same wires with one exception; it has second Black.

I had an old power supply with 2 SATA connections and a long lead. I snipped it off and connected it to a 4 pin female molex connector, tying the two grounds together.

Before installing it in the intended machine, I threw together a system board and power supply and connected an old SATA drive to see if it would spin.

Glad I did; I smoked the drive.

Am I missing something? There are 4 Pin Molex to SATA power adapters available for purchase, so it can be done.

Any Ideas?

Thank you in advance.

Nick

On a normal molex connector, both middle wires are black/0V. So, assuming your molex connectors are wired correctly aside from not following the normal color code, you shorted whatever the HDD has on 3.3V to ground.
considering how cheap they are you might wanna buy a dozen instead of smoking another drive.

edit: if you look at the adapter:

the 2 black wires come from the middle pair of the molex and go to the middle/left pins of the sata. i'm guessing you hooked them wrong? also the yellow red are inversed look at the direction of the L on the sata and the molex from the pic and yours
