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 power consumption grows up depending on the number of active execution threads in LinX.

Intel mainboard is a little more energy-efficient, even during overclocking, although we had to increase the voltage a little more than we would on Gigabyte mainboard. But you will only notice it when the overclocked processor is utilized 100%.


Overall, Intel DP67BG left a very stable, moderately positive impression. Like any other mainboard, especially an Intel one, it has some drawbacks. The worst one of them is, probably, the user-unfriendly BIOS, which is very inconvenient to work with. However, one can get used to almost anything. Besides, once you configured your system, there is really no need to access the BIOS anymore, so we do not consider this drawback something critical. Remember, that the BIOS functionality was sufficient to overclock our processor to its maximum. Besides, the board also pleased us with extended options for managing the fan rotation speeds, temperatures and voltages, which no other contemporary mainboard offers at this time. This is truly impressive and gives us hope that we will soon see even more dramatic changes in the BIOS of Intel boards.

There are very few specific peculiarities in the mainboard layout. They are the connector pad for the front panel buttons and indicators rotated by 180 degrees and the power supply connectors that have been moved to an unusual spot. Among other things we could mention the missing locks on the SATA cables and connectors, but this is hardly a serious issue as well. These few little issues can be overshadowed by a special discrete WiFi/Bluetooth module and higher energy-efficiency of the mainboard under medium-high load.

Overall, it is a little strange that Intel doesn’t stress that much their competitive advantages. For example, the dynamic adjustment of the number of active phases in the processor voltage regulator circuitry depending on the current operational load is only mentioned on the boxes, but without any further details. There is a mention of “Maximum ePower” technology in the brief description of the boards, but what does it actually mean? Unlike other manufacturers, Intel doesn’t stress that the board is based on the new B3 chipset revision of P67 Express, which is free from the well-known bug. Instead, they would like us to trust the “Better together” concept, which implies that Intel processors work best with the mainboards from the same maker. And why is that? There is not enough convincing proof. In case of the unique Intel DX50SO2 mainboard, I agree, it is better together. But if you ask me about other Intel mainboards that I have tested so far, then I would rather have just the Intel CPUs. As for the Intel DP67BG mainboard that we reviewed today, then this slogan would sound more like “together just as good”.
