jp7189 Im tying up entirely too much space in a storage closet because I keep PSU cables in their original packaging. Heck, I have a Corsair AX1600i with different cables from a Corsair HX1200. After I learned that, I'm paranoid that Focus and Prime cables might be different, so I keep them seperate too. It doesn't help that that all the wires are black now. Unlike in the past, you can no longer easily tell which pin has which power rail. You'd have to do a full pinout trace, and no way I'm spending the time on that. Reply
edzieba The good news is that the platters will be fine, the heads will probably be fine, and it's just the driver board that's let out the magic blue smoke. That means date is very likely recoverable by taking a drive of the same model and revision, and swapping the good board form that to the damaged drive, with no need to crack the housing. Reply

Straight board swaps haven't worked for over a decade. "Adaptives" — why PCB swaps don't work in modern HDDs The latest PCBs have unique keys in the MCU, which is an additional complication. Edit: Most HDDs supply 5V to the preamp on the headstack. If 12V is applied to the 5V input, there is a very real risk that the preamp may be damaged. Most modern drives have some kind of overvoltage protection, either via TVS diodes or electronic fuses, but these are not infallible. Older HDDs, and many SSDs, have poor protection, or none at all. Here is one example: Catastrophic failures in WD PCBs Here is what happens to the preamp: https://www.hddoracle.com/download/file.php?id=9531&mode=view Reply

Enthusiast fries 14TB HDD due to SATA power slipup — bemoans lack of SATA power safety and modular PSU cable standardization : Read more This is news? This same scenario has been acted out in numerous threads in Tom's Hardware's own storage forum over the past decade. I, myself, have helped numerous users rescue their own data at zero cost.

bit_user The article said: The underlying issue is the lack of standardization between PSU makers — and even between PSU models from the same brand. Uh, I definitely have swapped modular PSUs of the same brand, without redoing the cabling. I suppose I just got lucky. Sigh. Seasonic previously used sleeved cables and has now switched to flat, ribbon-style cables that are easier to fold but definitely don't look as nice. When I upgrade one of my machines that's still wired with those cables, I was planning on exchanging the PSU but keeping the cables. Now, I'll probably try to find out if they're compatible. At work, I even brought in one of my Seasonic cables to get either 6-pin or 8-pin power from a Dell workstation PSU. In that case, I seem to recall I did go to the trouble of using a multimeter to check that the pinouts were the same. ATX 3.0 should've standardized this stuff. : ( Reply
NightHawkRMX Very likely that drive can he saved by just removing the TVS diode or bridging some fuses Reply
MobileJAD I really wish PC component companies could get their act together and standardize this kind of stuff. This type of scenario where the wires for power dont line up correctly on the power supply could only get worse if someone building a new PC opts for more blingy components a discards the modular power cords that came with with their power supply for some cheap aftermarket cords they got online that promises fancy colors or what not. Right now I have one large SATA HDD in my PC where I throw all of my old files and I got some USB HDDs that hold offline backups of videos that cant be replaced, maybe I should buy another USB HDD or get back into burning stuff I dont want to lose on to blurays again.

You should always have backups. 2. Never ever mix cables from one PSU to another. This has been a known thing since forever. The pinouts are standard at the component end. They are not standard at the PSU end. Reply

I guess im just agreeing with others that it would be nice if companies could have standardized those connectors on the PSU end? Or maybe it wasnt that bad afterall to have power cords for your components that were hard wired to the power supply? The only real benefit that I can think of with a modular PSU is that when you buy that super fancy 1,600 watt PSU for that new RTX 5090 you want and the PSU comes with enough SATA power connectors to power up 200 hard drives, you can remove those extra SATA power cords you dont need, along with the extra 4pin power cords, to regain some of your sanity… Reply

Yes but the only reason one should not mix cables is because they dont use standard pin layouts at the psu side, which is utterly ridiculous. Pretty easy to mix up a few sata cables when you have a lot of stuff going on. Yes you should have backups, yes you should not mix cables, yes you should double check. But you know what you should reaallly have? Right, standardized cables! And not blame consumers for this nonsense. Reply
