Why would I admit this? To give you an idea what may happen if you too don't make absolute certain the Molex wires are correct and then the plastic interconnects mate.
Yesterday I installed a replacement desktop USB 3 PCIE card and the Molex interconnect was backwards.
I had light: a room light on in the daytime, an extra light on an arm and a headband light on my forehead with a lot of LEDs, as well as bifocal glasses. I thought I connected it right, so connected a WD 1TB external hard drive. It spun up, got clicky and I unplugged it. Plugged in a SanDisk 32GB USB stick heard a crackle. Oh oh. I think it was Habibie who got me to buy a USB tester a while back - when the wiring was backwards there was no number under volts and a higher number for amperage.
Where I was very lucky, the rest of the computer is fine, and I have mostly a backup of the 1TB on another 2TB, but lost anything this winter unless I can find a way to revive the 1TB external hard drive. It lights, disk spins, but has a click and computer doesn't recognize it.
So you live, you learn - $100 down the drain and that one moment in time I should have made extra certain the parts weren't connected backwards playing over and over... but an old dog re-learned an old trick, that's good... waaaah anyway :-(
