[SOLVED] HDD SATA Power Connection Smoking

[olilja1217]

Hi, Yesterday I was adding an additional fan to my pc and then I decided to move my Hard Drive up a few spaces, since it was a little too close to the GPU for my liking. I had the computer open when I plugged everything back in and tried to test it. All of a sudden some thick black-Greyish smoke started coming from the hard drives SATA power connection (right on the “plug”, sorry I don’t remember the actual word for it) I quickly unplugged the hard drive and the pc. After, I disconnected the SATA power connections and inspected it, the whole thing was covered in melted plastic (mostly melted in the middle of the plug, from the PSU). My first thought was that the computer is dead, fried and ruined. Since my psu has I think 4 SATA power connection heads I covered the burnt one in electrical tape and then hooked up one of the other SATA power connectors. The HDD looked like it had some burn damage around the SATA power plugin, but I figured why not try and see if my pc still works somehow. After hooking everything back up (using one of the additional SATA connectors) it started up like I never even touched anything, the new fan I put in and everything worked fine. Should I be worried about anything burning again or about my PSU/HDD? I really don’t have the money for a new PSU or HDD so I was wondering if I need to do anything or replace anything. Everything works fine and there are no more plastic burning smells or smoke. Tested everything and nothing seems off, The HDD should be fine I think since it was only the SATA power connection that was possibly damaged not the actual data transfer connection. Thanks in advance. I built this pc myself for gaming and nothing was off for the past 6 months since it was put together.

looks like you may have had a problem with the connector.

Is the faulty sata connector on the same string as a working connector or is it on a separate string?

Is it a modular PSU, if so, are you sure you plugged all SATA power cables into SATA sockets on the PSU end?

@asoroka, it’s not a modular PSU. The SATA power connectors are all connected on same wires. I just hooked up the the HDD with the one next on the wire from the burnt one and it seems fine, I’m pretty sure the reason it melted and nearly lit on fire was because of a short. I think that when I was connecting the SATA power there was something conducive stuck inside or somehow the connector got messed up. Like I said, Rn the melted one is covered in electrical tape and tucked a little bit more inside the case. I don’t think there are any more wires from the PSU that has the SATA power connectors. I’ve ran the pc for about 2 hrs now and it seems ok, I’m still worried something will short though.

If you don't touch anything, it should be fine.

Can you return your PSU under warranty, it should have 12 month warranty.
If the problem was with the connector, which it appears to be, you should try to get a free replacement.
