How to find reasons for NVME disk disconnection under GPU load?

Question

Solid State Drives

Processor i7-3930K PCI2.0, mother asus p9x79 le PCI3.0. OS Ubuntu Server 16.0 + Desktop on SSD SATA stand.
The SAMSUNG EVO PLUS 500Gb NVMe drive is connected via an M2 to PCIE3 adapter.
Data is written to the NVMe disk in MySQL. Everything seems to be going well for a few hours.
But as soon as I start processing data on the GTX 1070 GPU, the NVMe drive falls off after a few minutes.
How can be cured?

Answer 1

Most likely a food problem.
There is a power drawdown - the disk falls off. SSDs are generally very demanding on power quality.
The temperature should also be monitored, but this is less likely - as a rule, when the drive overheats, it goes into throttling, it just works slowly.

Answer 2

Alternatively, severe overheating

Answer 3

Wangyu overheating. NVMe does not differ in coolness anyway, but here, in addition to writing to MySQL, the video card also heats it up. Glue radiators, yes more.
