Matrox Radient eV-CXP - Electrical and I;O Specifications

52 Appendix B: Technical information
Electrical specifications
Matrox Radient eV-CXP (starting from version 000)
Operating voltage and
current (eV-CXP )
Typical: 3.3 V, 425 mA: 1.4 W
Typical 12.0 V, 1.2 A: 14.4 W
Max. PoCXP 18.5 - 24.0 V, 700 mA: 17 W
*
(Current drawn from the PCIe auxiliary power connector. Power is not
dissipated by the board; it is only used by the video source).
Total dissipated by the board: 1.4 W + 14.4 W =15.8 W
Total dissipated by board and PoCXP video sources = 15.8 W + (4 * 17 W) = 83.8 W
