Power Consumption Procedure

We performed our power consumption measurements using the Extech Power Analyzer 380803. This device is connected before the PSU and measures power draw of the entire system (without the monitor), including power losses occur in the PSU itself. In idle mode, we start the system and wait until it stops accessing the hard drive. Power consumption in the case of single-threaded CPU load is measured when running the Pi-digits performance test, and in case of multi-threaded load when running Fritz Chess Benchmark test. We also used the Hitman Absolution game to create complex loads. The results on the diagram are sorted in ascending order and the results of the Asus P8Z77-V LK are marked with darker color for your convenience.

This is one of the advantages of the P8Z77-V motherboard that CPU-related power-saving technologies work correctly in its operations and are enabled by default. You don't have to manually activate them. However, the power consumption of this model is not low. It is equivalent to the Gigabyte GA-Z77-D3H and higher than the ASUS P8Z77-V LK and MSI Z77 MPOWER.

The ASUS P8Z77-V requires less power than the flagship models from ASRock and ASUS's but its energy needs are not typical for conventional products because it has an extra PCI Express switch.

Now let us compare the power this system needs when overclocking.

The obtained results are almost the same. The ASUS P8Z77-V is expected to need less energy compared to two special models but its power consumption is higher than the ASUS P8Z77-V LK and MSI Z77 MPOWER.

Conclusion

We mention a few drawbacks in our P8Z77-V review but most of them are typical for all or at least many other ASUS mainboards. We would like to say that the boot image doesn't have enough information and the wrong CPU clock rate is reported during the POST procedure. Turning the startup image off isn't saved in the boot profile of the BIOS and the board can't adjust the speed of the 3-pin CPU fan depending on temperature. We also mention the specific limitations of this particular model. This chipset does not provide too many PCIe sockets and the board does not have extra PCIe switches, so you will have to compromise. You can't use a third PCIe 2.0 x16 socket, PCIe 2.0 x1 sockets and the extra SATA 6 Gbit / s controllers simultaneously. The downsides, however, are not too serious and not interfere with the function of the mainboard.

In terms of improvements, the ASUS P8Z77-V comes with many accessories, has user-friendly PCB design and provides a lot of possibilities. Its advanced digital power system SMART Digi+, working together with Dual Intelligent Processors 3 technology, offers flexible voltage regulation option, which is important for good overclocking. The mainboard allows using an integrated graphics core CPU, but you can also run one or more discrete graphics, combine them in AMD CrossFireX or NVIDIA SLI configurations. The P8Z77-V features additional SATA 6 Gbit/s and USB 3.0 controllers. It has handy Q-DIMM and Q-Slot connectors, Q-LED indicators, MemOK! and USB BIOS Flashback technologies. Its ability had made it a key product just for a few years, but now you can get all this with a basic mainboard, which the least advanced of ASUS’s top-end Z77-based offers. This is the first time we see a modest product support wireless technology. Thus, the P8Z77-V will be an optimal choice for a variety of users.

Choosing the junior model from among top-end offers often makes sense not only with mainboards but also with CPUs and graphics cards. The opposite approach can work, too: take the most advanced of entry-level products and you get about the same range capabilities. We’ll talk about one such mainboard in our upcoming review.

Choosing a primary model of high-end models often make sense not only to the motherboard, but also to the CPU and graphics card. An opposite approach can also take advantage of: take the most advanced of entry-level products and you get about the same range capabilities. We will talk about such mainrboards in our upcoming review.

In conclusion we want to give the Asus P8Z77-V the Recommended Buy title.
