Toshiba SSD no power..

Hi friends!

I hope I can get some help.

I have a Toshiba SSD (THNSFC128GBSJ) that doesn't get any power. I plugged it into PC3K; the SSD gets ready, but without power input.
The controller is not supported. I already checked the capacitors to ground and didn't find a short.

Does anyone have any advice for me? I would appreciate it!

It can't get ready if it's taking no power. Check what voltage rails you actually have present and lets see what PC3K universal util actually shows.

There appears to be an smt fuse at the SATA 5V input. Check if 5V is present at the "GU" diode.
