My HDD smoked and fried

[Ghosto1]

Hello everyone. Today I was upgrading my computer from an AMD cpu to an intel. I also was changing my PSU. After plugging everything into the Intel mobo and new PSU my HDD started smoking after flipping the power. I do not get a post screen at all with the intel mobo regardless of old or new PSU. My HDD is definitely fried, I know this because I went back to my AMD mobo, used my new PSU, and got a bios screen saying no bootable device.

Can anyone explain what happened and what needs to be replace exactly? (Including the HDD)

Hello Ghosto1,

There is no reason why a hard drive should be smoking from fault of its own. That almost had to be an error with your power supply. Either you accidentaly plugged the wrong power into the hard drive or the PSU is unstable. The error, one way or the other, is almost certainly with the power supply.

Would you please list exactly what hardware is in the build that started smoking (motherboard, power supply, CPU, etc.)?

Also, could you describe in detail how you had the hard drive connected?

You may have plugged the wrong psu cables on your motherboard since your were changing psus

The only thing that smoked was my HDD. I had it connected from my PSU, to my disk drive and then my HDD with a sata power cable

My intel mobo definitely does not show a display at all, connected to the board or the gpu. I personally think the PSU is fine and it's just the mobo but I don't know

Hang on... I think I found the problem. I just now noticed that I may have used the wrong SATA power cable. I was actually checking to see which cable had a smoked smell and I noticed that one of the cables had a different end that connects into the PSU. Like the pin in the inside is missing on a different corner from the new other cables. Is it possible that using the older PSU's cable fried my HDD and disk drive?

There's no wrong SATA power cable, the only thing where you could somehow make a mistake is on PSU side of cable although most (semi) modular PSUs have different connectors/plugs and putting wrong cable in a wrong place would require considerable force.
Which PSU is that ?
I still don't know what's wrong with reading instructions before doing something. Even after 30 or more years working with computers I still read instructions even before I acquire parts. No shame in it because you never know if manufacturer made a part by some of their standards.

I had a CX750M going to a EVGA Supernova P2

Maybe you used cables from first PSU on second one ?

 

[Ghosto1]

Oh no that's what I meant in the reply earlier, I think that I accidentally used a sata power on the new psu. Both my HDD and disk drive were connected to that and they both fried. The thing with the mobo not displaying at all is a different problem I'm thinking.

Do you think my PSU needs to be replaced at all?

It's quite possible, positive smoke test is no good in electronics.
