Raspberry Pi

Uploaded Raspbian to SD card. The device turns off (the screen goes blank, stops responding to everything) a short time after starting. (1-5 minutes. The OS has time to boot by then.)
Google says to check the voltage on the board. I measured it - 4.5 V. The power supply from Sony is 1.5 A. I tried the power supply from Asus at 2 A and even connected them in parallel, but the result is still the same. What to do? Carry it back or look for another power supply?

PS: I also tried it from a computer.

It was a marriage. I returned it to the seller, they did an examination and replaced it. Thank you all for your help.

And what about the temperature? There was a lot of information on the Internet about overheating.

I don’t think it’s a power supply, I have it powered by an old 500mA charger. And USB is not loaded with anything? It's worth keeping an eye on dmesg, maybe it will clear something up.

4.5V is where? At the output of the power supply? I think this is out of range (+-0.25V).
If this is Model A, then you can safely run it from the computer's USB port (most importantly, not through the USB hub).

Try re-uploading the image to a USB flash drive, there was a similar case, the fs was beaten, it seemed like it started loading, but then it stopped and started blinking weakly with a green LED (I don’t know what was on the screen, but ssh didn’t rise). Fixing the fs / reuploading the image helped me.
Overclocked? at a frequency of 1 GHz, the axis often either did not start or immediately hung. (I think there was not enough voltage because it fed 5V / 0.55A).
PS: I have Raspbian.
