[strike][/strike]TLDR at bottom.

I just replaced my 1 year old PSU, a Corsair CX750M, with a EVGA 1000P2, and on the very first start up with the new PSU I get a burning smell and immediately turn it off.

I check everything and it seems fine, turn it on and no smell but my system is unstable, at first not detecting any storage devices and upon switching SAtA ports it BSODs after 30 seconds on the desktop.

I noticed I was using the SATA cable from my older corsair PSU and changed them out for the newer EVGA one. The PC starts and runs fine but it does not detect my HDD. My OS is on a Samsung SSD with bulk storage going on the HDD which is a Western Digital Black 2TB. Regardless of the SATA port or cord I use it does not detect the HDD in the BIOS or device manager. When I was still getting BSODs my custom Rain Meter desktop was loading in, which stored it's skins on my HDD, which means it was still partially working after the burning smell and stopped working completely after I changed SATA cables. The pc still detected the 2nd hardrive before switching cables but listed it at 0/0 space.

I removed the HDD and learned that the electric smell had emanated from the HDD. I have no clue of knowing but I assume that due to me using the other manufactures SATA cables I possibly fried my HDD, I haven't switched back to the old PSU because ofnthe time sink and i haven't used the old SATA cable again for fear of another possible incident.

Is there any way of knowing if my HDD is toast or if the problem is still possibly something to do with the new PSU? I switched my SDD over to where my HDD was previously installed (Corsair 540 case with built in hotswap bays) and the bay still works fine so it isn't the connection, i believe. I contacted Western Digital and hopefully there is something they can do if the HDD is truly lost, it is only a year old.


TLDR
Possibly destroyed my Western Digital 2TB Black HDD with a new EVGA PSU due to a Corsair SATA cable but no apparent physical damage other than a burnt smell coming from the connection ports on the HDD.

Is it possible a different companies SATA cord fried it or, if not, what could have happened and is there a possible fix?



Sorry if there is too much information, I just wanted to be as precise as possible.


Any help is truly appreciated.
 
Hey there, sargentchimera.

This sounds like a truly unfortunate situation. :(
Does the drive even spin-up? From your description it sounds like its PCB might have been fried. Basically different power cables don't matter. You should have either a 4pin Molex (if the drive has the option for such a connector) or a standard SATA power connector, but never ever have both connected. So if it wasn't a faulty cable, I'd say that there might be an issue with the PSU and if I were you, I'd get it diagnosed for problems at a comptuer service shop, just to be on the safe side.

Unfortunately if the PCB is gone, then probably the only hope for data recovery would be a professional solution, such as a data recovery company: WD Data Recovery Partners.

Hope that helps.

Agreed with Boogieman that it sounds like a bad PSU fried the HDD's PCB. 3.5" HDDs use 12V to spin up when turned on, 5V to power their electronics. Cross those two and it'll fry the electronics. 2.5" HDDs and SSDs only use 5V. That may be why the SSD survived.

The SATA data cable does not carry any power. Only the SATA power cable does, and they're all connected by wires which go to the same power rails on the PSU. So the possibilities I can think of are:

  • ■The SATA power cable was wired wrong and was sending 12V over the 5V pin.
    ■Some of the wires in the SATA power cable are shorting out.
    ■If you've got modular power cables, the key broke off and you inserted it the wrong way, or you used a modular cable from a different PSU.
    ■The PSU's power rails are putting out voltage that's out of spec. Grab a multimeter and check the 12V and 5V rails on the EVGA PSU. If it's out of spec, you may have success getting EVGA to pay for your damage and data recovery.

I was using a SATA cable from a Corsair modular PSU at the time and not one from EVGA, is that what you meant by different modular cables?

I am not too upset about the data loss, it was mostly music I have backed up and games which I can redownload eventually. I am just glad nothing else is toast and that Western Digital will replace the HDD under their pretty great warranty.

I've played some intensive games to test it and everything seems fine. The SATA bay the HDD was in I tested with a SDD, not an HDD, so I am not sure if all HDDs will fry upon connection but the SDD did work fine through that bay.

I suppose I will find out when the new HDD gets here in a week or so. If anyone has any suggestions that might allow me to salvage my current HDD let me know! I haven't fully committed to the RMA process yet, just in case there is something that can be done.

I have not, I do not have access to another.

I've talked with some more tech savvy friends and they say it was likely he SATA cord as apparently different manufacturers make the cords midly different, that as well as going from SATA cord for a bronze psu to one for a platinum certified.
