System-Level Power Consumption – 470 Watts

Ad

Compared to the X38 desktop chipset, which itself is not exactly a very modest part, the 5400 workstation northbridge draws even more power.

2 active33.2 W36.2 W
4 active35.0 W38.0 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, our 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 our Skulltrail board, its power consumption is a full 128 Watts higher than that of a single-socket system.

page 14 - two copies of same "Power Consumption 100% Load" graph = boob??!!

Spuddyt you're wrong!!

Anyone buying this board will have problems paying off those maxed out credit cards when their power bill comes in!! (Well we are talking enthusiasts right??)

I bet the lack of memory speed settings is more than just a beta issue... Intel will use it as a means of preventing ludicrous levels of Xeon overclocking and force anyone crazy enough to buy SkullTrail back onto the crack... er, I mean back to EEs, with their unlocked multiplier, relatively poor overclockability and 500% price premium. Per CPU. :P

Anyone know where we can buy it in the US ?
