Asus P8Z77-V LE Plus - The Flagship In The Entry-Level Lga 1155 Line Of Asus (Part 4)

Power-consuming process

We perform our power-consuming measures by using Extech Power Analyzer 380803. This device is connected before PSU and measure the power level of the entire system (no screen), including the power loss happening even in PSU. At idle mode we start up the system and wait until it stop accessing the hard drive. Power consumption in case of single-threaded CPU is measured while running Pi-digits efficiency test, and in case of multi-threaded load – while running Fritz Chess Benchmark test. We have also used the Hitman Absolution game to create complex load. The results on the diagram are all arranged in ascending order and the result of Asus P8Z77-V LK is marked with darker color for your convenience.

Unlike other basic motherboards from ASUS, P8Z77-V LE PLUS doesn’t save energy. Though the power-saving tech related to the CPU of Intel is activated on it by default, it still needs plenty of power. Though it need much less power than the premium model of ASRock and ASUS, it power need is not a typical of the regular product because it has an additional PCI Express button.

You can try to make it save more, even at high load and idle mode, by allowing EPU Power Saving mode in BIOS or with switching to airport mode.

Now, let’s compare how much energy this system need when overclocking.

P8Z77-V LE PLUS is compared about power consumption to other usual motherboard at default settings, but it’s the most saving one among those at overclocking settings (with the exception of 2 special models). That’s an embarrassment for a basic product which is expected to need little power.


Like most of other motherboard from ASUS, P8Z77-V LE PLUS leaves a good impression in general look, but it somewhat spoils due to having no ability to overclock CPU to its max, because of high power consumption (especially in overclocking). This is not a very serious disadvantage as the extra100 MHz of CPU clock rate can’t ensure the operating efficiency benefit and power consumption is not actually terrible, but we’re very disappointed.

P8Z77-V LE PLUS stands at the middle place of the product of ASUS. It has mode functions than the basic products, has more advanced electric system and USB Flashback BIOS support, but it doesn’t save energy.

Like other ASUS motherboards, it has the advantage as an easy-to-use and 3-year- PCB design and it lets out some of its own benefits. You need to notice that while it’s for sale at a remarkably cheaper price, this product model offers the same features as P8Z77-V. It only lacks wireless techs, but instead of having an eSATA 6 gigabit / second port you can’t find on P8Z77-V. Being the most advanced basic model, it lags behind P8Z77-V, the least convenient model in the towering models of ASUS motherboard. However, if you don’t expect too much from P8Z77-V LE PLUS, it won’t let you down.
