I recently bought a Raspberry Pi 4 Model B. This is the first time I have bought a Raspberry Pi. As per my understanding, the recommended power supply is 5.1V / 3A. I am using a different power supply that can deliver up to 5.1V / 2.7A. However, the Pi doesn't seem to draw more than 1.25A on average with a fan on GPIO and one USB device connected. Even with stress test (stressberry), the maximum current draw was around 1.7A.
Is my Pi 4 original or is it some fake with under-powered fake components?
PS: I am measuring the current draw with an in-line USB power meter.
