MSI Big Bang-XPower II X79 Review – A World of Novelty Heatsinks

Test Setup

Power Consumption

Power consumption was tested on the system as a whole with a wall meter connected to the power supply, while in a dual GPU configuration. This method allows us to compare the power management of the UEFI and the board to supply components with power under load, and includes typical PSU losses due to efficiency. These are the real world values that consumers may expect from a typical system (minus the monitor) using this motherboard.

For an XL-ATX board, the MSI BBXP2 is spot on in its power consumption, being the most energy efficient (or the second most efficient) by default compared to other X79 boards tested.

CPU Temperatures

With most users’ running boards on purely default BIOS settings, we are running at default settings for the CPU temperature tests. This is, in our outward view, an indication of how well (or how adventurous) the vendor has their BIOS configured on automatic settings. With a certain number of vendors not making CPU voltage, turbo voltage or LLC options configurable to the end user, which would directly affect power consumption and CPU temperatures at various usage levels, we find the test appropriate for the majority of cases. This does conflict somewhat with some vendors' methodology of providing a list of 'suggested' settings for reviewers to use. But unless those settings being implemented automatically for the end user, all these settings do for us it attempt to skew the results, and thus provide an unbalanced 'out of the box' result list to the readers who will rely on those default settings to make a judgment. CPU Temperatures are not really indicative of quality or performance, even though one would postulate that worse parts may produce higher temperatures. However, if a manufacturer uses more conductive material in the power plane, this reduces resistance and increases the voltage at the CPU, causing a higher temperature but potentially better stability.

Impressively, the novelty heatsinks on the MSI seem to work wonders, producing our lowest ever CPU temperatures in idle, video and OCCT mode.
