> When using a standard 5V, 3A (15W) USB-C power adapter with Raspberry Pi 5, by default we must limit downstream USB current to 600mA to ensure that we have sufficient margin to support these workloads. This is lower than the 1.2A limit on Raspberry Pi 4, though generally still sufficient to drive mice, keyboards, and other low‑power peripherals.
This is also very uncool, since powering it through the GPIO header with a capable PSU won't trigger the PD signal and makes it impossible to draw any meaningful current through USB? I hope this blockade can be worked around in the boot config.
I mean theoretically dupont connectors are rated for 2.5 A so two of them could get it done, but the current will never be completely equal across both and one may get overloaded. Maybe the safest option would be to find some kind of barrel-jack-to-usb-c dongle.
In practice I doubt it would be a real problem since you'd need to max out both the USB draw and CPU load at the exact same time to get the full draw.
