Understood, will test later with proper leads, thanks Image may be NSFW.If I am right about this, most of dupont jumpers are 28 AWG. This means that the max permissible current is around 1 Amp on those.VIdeo is processed and ready nowWell I made another video - see somehow I have to set my bench power supply to 5.4V or even 5.5V in order to get 5.0V on a Pi. And power supply does output close to what's expected. At the same time with a Pi 5 official PSU I get like 5.09 or something right away without any issues. I wonder why - could my tiny leads really be the root of the problem? If so - I'am sorry for bothering you, proper leads will only arrive tomorrow and I'am testing with whatever I have at hand Image may be NSFW.

You're going to need thicker wires than those thin dupont wires you're using to power the pi via the gpio headers if you expect the PI to be able to draw all the current it needs. Never mind that you have a drive connected to the usb port and other stuff, all of which need to draw power too.
Those wires are causing the voltage to drop because they are not thick enough.
