| 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. |
