How to solve the problem with the voltage on the 12v line in the PSU?

Question

Power Supply

The problem is the following: recently the computer has increasingly begun to reboot under load, sometimes it did not turn on for no reason. In Speecy I checked the PSU voltage, on the line 12v = 8.6v. I actually bought a more powerful power supply (corsair cx 600w), the situation remained the same, in speecy it shows the same abnormally low voltage. Unfortunately, there is no tester for bp.

Programs can lie godlessly. Look in Hwmonitor ( www.cpuid.com/softwares/hwmonitor.html) and/or bios. Well, since a new PSU, then with the power output it should be good, if of course it is enough to feed everything.
Regarding reboots: Judging by the question, you have Windows. In the system settings, see if dump creation is enabled and you can disable automatic reboot. In such cases, you will see the "Blue Screen of Death" and there will be an error code. Well, windows dumps it into the minidump folder (somewhere in the windows pack), there are programs that read them and give out human error codes, which also cutely google in search of a solution.
