Power Consumption

We performed our power consumption measurements using an Extech Power Analyzer 380803. This device is connected before the PSU and measures the power draw of the entire system (without the monitor), including the power loss that occurs in the PSU itself. In the idle mode we start the system up and wait until it stops accessing the hard disk. Then we use LinX to load the CPU. For a more illustrative picture there are graphs that show how the computer’s power consumption grows up depending on the number of active execution threads in LinX (both at the default and overclocked system settings). The mainboards are sorted in alphabetical order on the diagrams.

Intel mainboard turned out the most energy-efficient of all, although it was only slightly ahead of the competitors. The only exception is our today’s hero – Asus Sabertooth P67, which consumes considerably more power during overclocking and heavy CPU utilization.

Conclusion

Our tests showed that despite radically unusual looks, Asus Sabertooth P67 mainboard is a typical product from this world famous manufacturer. In this context the word “typical” has purely positive connotation, because Asus mainboards always please us with convenient design, wide range of supported features, excellent configuring and overclocking functionality and well-establish technical support system. The drawbacks, if there are any at all, are usually insignificant. All this is totally true about Asus Sabertooth P67 mainboard, although it has an additional advantage over other regular mainboards: prolonged warranty period of 5 years.

As for the drawbacks, we could probably point out the lack of “Asus Probe II”, “FAN Xpert”, “EPU” and “TurboV EVO” programs in the AI Suite II utility suite. This is a minor omission, because the new “Thermal Radar” utility replaces and even extends the functionality of the first two. As for the other two, you can do just fine without them, because all the energy-efficiency and overclocking settings are available in the mainboard BIOS. In our Asus Sabertooth X58 review we mentioned that we hoped there would be more TUF series products out there, which offer a unique combination of superb functionality, low price and long life span. Overall, our expectations came true, although the implementation of TUF Thermal Armor and TUF Thermal Radar didn’t come free. To our regret, the new Sabertooth P67 costs considerably higher than other regular Asus mainboards with more or less similar functionality and features. We are still a little uncertain whether the new technologies are a necessity, but the 5-year warranty period is undoubtedly totally worth it.
