Benchmark – Power Consumption & Temperatures

When it comes to the X79 chipset and extreme processors, it’s no surprise that you will need a little more juice to run the system. The TDP on the 4820K is set at 130watts, so we know that we will need some decent power to push this system especially running TRI SLI configuration. Luckily, our Cooler Master V1000 has no issues handling this set up.

To test the power consumption, we used three methods. We used a wall socket meter to get our readings and let the system sit at idle. Then we used CPU load ONLY and then both CPU and GPU Load.

So let’s take a look at the results.

Power Consumption 

Full load we saw some high numbers, however keep in mind that we are also powering a entire watercooled TRI SLI system.

Let’s take a look at some temperatures during the testing. Here we used software to monitor the temps like CoreTemp and the AI Suite.

Temperatures 

Looking at the results of the temperature test, you can see that the Motherboard temps performed great even under full load and even overclocked temps only moved a few degrees. The highlight here is that at 4.64GHz, it topped out at 70c under load testing. Taking into consideration the higher TDP on the 4820K, it didn’t perform too bad.

Well, that pretty much sums up our benchmarks so lets wrap things up.

    If the P9X79-E WS only has 40 PCI-E 3.0 lanes… then how does it run 3-way SLI or 4-way SLI at x16 speeds? I thought that it had to equal the total number of lanes (i.e., 40)? So then 40 lanes would be achieved by:

    3-Way SLI: x16 +x8 +x16 = 40 lanes
    4-Way SLI: x16 +x8 + x8 + x8 = 40 lanes

    So how do they pull off 3-Way or 4-Way SLI with each card running at PCI-E 3.0 x16 speed (which would seem to require 48 lanes or 64 lanes respectively)? Am I misunderstanding something?

      Hi Archangel,

      This motherboard uses two PLX PEX 8747 chips to increase the number of PCIe 3.0 lanes on the motherboard from 40 to 72. That is how the board is able to handle the full X16 lanes on the PCIe slots.

      or respectively x16/x16/x16/x16 and x16/x8/x8/x8/x16/x8/x8.
      Sorry this information was not touched on in the review, I will be sure to update it.

      Thanks!

    This motherboard uses 2x plx chip to achieve 4 way 16x sli , Asrock extreme 11 uses somthing similar.
