Today i found a cheap PD compliant power supply which claims to deliver 20 watts max and i bought it. I then found out it is only 15 watts max when the current is 5 volts. Anyway, up to this point, i was using a standard 15 watt (5 volt - 3 amp) power supply with which i wasn't getting any "undervoltage" messages and it was working fine for me. I said what the heck, let's try this one, and after i connected the new supply to my Pi, it actually recognised it (i saw 15 watt PD in the bios messages). However, i am getting a lot of "undervoltage" messages in dmesg.
So is it a fauly unit (the power supply i mean)? The usb-c cable is also new and rated for 65 watts.
