Hi. Monica told me to report this here.
So the X1 can consume much more than the PSU is rated for.
Idle nothing connected 9.3W
Idle with NVMe + mouse/keyboard 11.4W
Idle no NVMe 7" display + mouse/keyboard 15.3W (display consumes about 4W)
Maxed out with NVMe + mouse/keyboard 38.9W
Maxed out USB3 to SATA SSD + Display + USB keyboard/mouse 46W !!! More than PSU is rated for
So using the 7" display + USB3 SATA SSD + mouse/keyboard and all cores maxed out it goes to 46W.
Measured between the plug and PSU.
Not even using an NVMe here.
So I would expect it to be more with NVMe. And then adding a SATA device over SATA ribbon would bring it above 50W.
I do think there is some loss from the PSU.
I don’t have anything to measure at the input of the board(barrel jack).
The boost clocks have a huge impact on power consumption.
Here a short video where I show this behaviour.
Should we use a 12V 5A PSU instead if using a lot of IO?
The data we tested is much lower than the data you tested，
may i ask Does it include the power consumption of the HDMI monitor？
the max output of our power adapter is 36W(12V3A),Why it can show the 45W on your tester？in the video i saw the power adapter is plug in your white tester,
This is the data we tested of the X1 power consume
- windows 10 pro on eMMC
- HDMI out to monitor
- RTL8822CE module
No other peripherals,
The power supply is connected to a high-precision regulated power supply, and the values can be read directly
I am not powering the 13" display with it. That’s in another PSU.
Do know there is loss in converting 240V to 12V.
But it should not be this much.
I am powering : USB keyboard + mouse dongle. Wifi adapter. 7 " Display. USB3 to SATA SSD.
I am also maxing out all cores(at 2.6Ghz). That is something you don’t seem to be doing in your tests.
I use Blender to do this.
Blender is able to use 100% of all cores at the same time. So it’s a good stress test.
I could also have added NVMe and even a SATA disk over the SATA ribbon and then it would be even higher.
The difference between idle (11.4W) and maxed out (38.9W). This with NVMe + mouse/keyboard dongle only.
I added the USB3 SATA SSD + 7" display and got 46W.
I should see to buy a clamp voltage meter so I can measure the input on the 12V line.
