1217 I want to provide my own power to the Echo Express SE IIIe. What do I need to provide?Apr-11-23
The Echo Express SE IIIe comes with a 120W power supply that provides 12V at 10A. The SE IIIe can tolerate 12V +/-8%.
The power budget is:
15W for upstream power delivery to the computer (if your computer is otherwise powered, you do not need)
15W for downstream bus power (if you have no downstream device or a wall-powered downstream device, you do not need)
75W (25W each) for three PCIe cards (you need to budget for your PCIe cards; most cards do not take nearly this much)
10W for internal use (required)

The connector is 5.5mm/2.4mm.
Four spring contacts on connector 2.4mm inner barrel required at 120W.
Two spring contacts on connector 2.4mm inner barrel required at 60W.
