System-Level Power Consumption - 470 Watts
Compared to the X38 desktop chipset, which itself is not exactly a very modest part, the 5400 workstation Northbridge draws even more power.
|Power Consumption of the 5400 Northbridge|
|1 active||32.3 W||35.3 W|
|2 active||33.2 W||36.2 W|
|4 active||35.0 W||38.0 W|
In addition, we need to consider the increased power consumption of the FB-DIMM modules and the two additional Nvidia SLI-Port switch controllers.
In the end, the power meter measured a power consumption of 470 Watts for the entire system. This includes two hard drives, a Creative X-Fi and an Nvidia GeForce 8800 GTX.
Overclockers should budget for a very brawny power supply, as the system will consume an unbelievable 623 Watts.
Since the Speed Step power-saving feature is not yet working on the Skulltrail board, its power consumption is a full 128 Watts higher than that of a single-socket system.
