Disconnect power supply from electrical outlet
a. Connect the EPS12V 8-pin power connectors
b. Connect the EPS12V 24-pin power connector
c. Connect power cable to power supply to power outlet
Make sure you have connected both connectors before attempting to apply
power to the board.
* w/ 4-rank memory: please connect total 5 power connectors before connect power
cable to power supply to power outlet.
NOTE: We suggest using a 700W or higher power supply; this is dependent on how
many devices you have installed. However, 700W is sufficient for system without
many devices (i.e. 4 x AMD Opteron 875 CPU, 16 x 1G DDR 333 Memory, 1 x HDD,
2 or 3 expansion cards). We suggest using a 1350W or higher power supply to
support a 8-way system (S4881+M4881). For 4-rank memory support, please
contact Tyan directly for related power consumption table.
