[SOLVED] SSD Preventing POST

[Harrison1858]

I recently bought a samsung 870 evo 1tb to go along with my m.2 however whenever I have the SATA power connector plugged in to it my pc fails to POST. My specs are: Mobo: MSI Z390-A Pro | PSU: Corsair TX650M | CPU: Intel i5 9600k (Base speed) | GPU: ASUS RTX 3060 OC | Windows 10

Test with another sata disk.

Are you using the original PSU cables, or have you swapped cables with another PSU? Don't try another SATA drive until you can answer this question. Modular PSU cables do not have standardised pinouts.

I am using the cables that came with my psu

If the only cable that you have connected to your SSD is the power cable, then a failure to POST must be some kind of power problem. Do the fans spin? If not, then this would suggest that there is a short circuit on the +5V supply.

The fans don’t spin. Is there a way I can fix this or do I have to replace my psu?

There will be a shorted protection diode or electronic fuse on the SSD PCB. TVS diodes are designed to go short circuit when exposed to an overvoltage. E-fuses should theoretically afford better protection, but they don't always survive.

In any case this means that your PSU killed your SSD, or perhaps you received a faulty SSD that was returned by another customer.

I would start by measuring the SATA power pins with a multimeter. Use the computer's case ground as the 0V reference. Don't attach any device to the cable.

BTW, see this tale of woe:

Will do thanks for the help

Also measure the resistance between the SSD's +5V and ground pins.
