I have two of these mini PCs: TrigKey S5 with Ryzen 5700U, 32GB RAM, 1TB NVMe SSD, Win11 Pro. They work very well for most uses. They are powered by a HuntKey 19V 4.74A brick with a standard DC5525 tip, which feels decently heavy.
When the brick is connected to the system through a 1 meter DC female-male extension cord (18AWG so decently thick), the system will black screen and reboot when multiple objects are sliced simultaneously in PrusaSlicer. One object is OK. Literally any other activity on the PC is OK. It is just this one specific thing that causes a reboot. I tried running HWInfo on a 20ms interval of >250 parameters and found nothing abnormal recorded at the time of the reboot. No BSoD, nothing logged in event viewer. Even Prime95 and OCCT cannot induce a reboot.
Take the 1 meter extension cord out, problem goes away. Utterly bizarre but completely reproduceable. The same thing happens on both PCs and their power supplies so it is not a unit specific fault. However, if you replace the power supplies with a Lenovo 20V 3.25A brick, the problem goes away, regardless of whether the extension cord is attached. At idle both the Lenovo brick and the Huntkey bricks sit at similar voltage. Haven't checked under load.
I know the simple fix is "replace with a better supply" and I will probably end up doing that, but I am curious as to what is going on here. Is there an LC filter missing in these HuntKey supplies I wonder?
