Strange problem Corsair AX860 vs Intel 320 SSD

I just installed a 7990 and AX860 PSU, and when I tried to start up the computer, it powered on for 1 second and then turned off. After spending some time troubleshooting, I found out of, that if there was power on my Intel 320 SSD, then the computer refused to start. As soon as I removed the power from the SSD everything started without any problems. The same applies regardless of whether or not the SATA cable is in, or if I use another cord / pot to power the SSD. It worked without problems on my old Seasonic S12-600W and otherwise same setup. Pretty weird?

The only thing I can imagine is that Intel's power-loss technology on the SSD for some reason is not compatible with the PSU. Does that sound like the most reasonable explanation or does anyone have a better offer?

Fortunately, it is now only my secondary SSD, but it would be nice if it worked.

An suggestions on how to fix it, would be greatly appreciated. 🙂
 
something must be shorted inside your SSD which is causing the PSU to short the moment its on.

Did u make sure u put the cables for the SSD in the proper orientation?
check the tabs make sure they were in the proper allignment..
 
Agree that you should test the SSD itself first. It might seem like an odd coincidence, but plenty of unexpected bad things can happen when you're working inside the PC.
 
Hmm, apperently my SSD is fried so badly that if I connect it to the computer it shuts down. Even in a USB enclosure, the PC shuts down instantly. I'm just glad I've backed up my data from it.
 
I think it semms like the power good signal is likely being lost when that SSD is attached. Must be a fault, probably a short circuit somewhere in the SSD causing the current to go haywire on the 5v rail whether directly from the SATA port or the USB port. Out of sheer curiosity, did the drive show any warning signs or did it suddenly do this?
 
Before I exchanged PSU, there wer no problems whatsoever, first time starting the PSU, it wouldn't start. So no warning.
 
Uhm, I might have an idea what went wrong. I might have attached the SATA plug into the 4x4 CPU plug on the PSU, since it was hard reading the text inside the case. And I didn't think it was possible to attach a wrong connector to the PSU.

!!! Yep, that'd do it. You sent it 12V on all pins where it was expecting a mix of 12V, 5V, and 3.3V.
