FAQ (3)
940 Can I connect an Echo Express SEL, SE I, SE II, SE III or SE IIIe; or Twin 10G to battery power?
The 12V tolerance is only +/-8%. Sonnet does not recommend attempting to power these units from an unregulated 12V source.
959 Why isn't the the OWC Mercury Accelsior E2 compatible with the Echo Express SEL?
This card is not compatible with the Echo Express SEL because this manufacturer didn't closely follow the PCIe spec. Because this card draws more than 3A at 3.3V (the PCIe spec), the manufacturer should have put a 12V to 3.3V regulator on their card, but did not. In a Mac Pro tower or HP Z840, it did not matter to borrow some 3.3V power capacity from an adjacent slot. However, the SEL does not have an adjacent slot from which to borrow.
The OWC Mercury Accelsior E2 card is supported in either the two-slot Echo Express SE II or three-slot Echo Express SE III.
1159 I want to provide my own power to the Echo Express SEL / SE-I. What do I need to provide?
The Echo Express SEL and SE-I come with a 60W power supply that provides 12V at 5A. The SEL and SE-I can tolerate 12V +/-8%.
The power budget is:
15W for upstream power delivery to the computer (if your computer 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)
25W for the PCIe card (you need to budget for your PCIe card; most cards do not take nearly this much)
5W for internal use (required)
The connector is 5.5mm/2.4mm. Two spring contacts on connector 2.4mm inner barrel required.
