Hardware Setup | Power Consumption

Hardware Installation

Installation of any of the Nvidia GeForce cards is really easy. Once the card is seated into the PC make sure you hook up the monitor and of course any external power connectors like 6 and/or 8-pin PEG power connectors. Preferably get yourself a power supply that has these PCIe PEG connectors natively as converting them from a Molex Peripheral connector anno 2016 is sooo 2008. Purchase a proper power supply, ok?

Once done, we boot into Windows, install the latest drivers and after a reboot all should be working. No further configuration is required or needed unless you like to tweak the settings, for which you can open the NVIDIA control panel.

Power Consumption

Let's have a look at how much power draw we measure with this graphics card installed. The methodology: We have a device constantly monitoring the power draw from the PC. We stress the GPU to the max, and the processor as little as possible. The before and after wattage will tell us roughly how much power a graphics card is consuming under load. Our test system is based on an eight-core Intel Core i7-5960X Extreme Edition setup on the X99 chipset platform. This setup is overclocked to 4.40 GHz on all cores. Next to that we have energy saving functions disabled for this motherboard and processor (to ensure consistent benchmark results). We'll be calculating the GPU power consumption here, not the total PC power consumption.

Measured Power Consumption

Mind you, the system wattage is measured at the wall socket side and there are other variables like PSU power efficiency. So this is an estimated value, albeit a very good one. Below, a chart of relative power consumption. Again, the Wattage shown is the card with the GPU(s) stressed 100%, showing only the peak GPU power draw, not the power consumption of the entire PC and not the average gaming power consumption.

Here is Guru3D's power supply recommendation:

  • GeForce GTX 1070 / 1080 - On your average system the card requires you to have a 450~500 Watts power supply unit.
  • GeForce GTX 1070 / 1080 SLI - On your average system the cards require you to have a 750~850 Watts power supply unit.

If you are going to overclock your GPU or processor, then we do recommend you purchase something with some more stamina. And remeber, a PSU is the most efficient at 50% load. So if you use 400 Watts on average (SLI), the most energy friendly powersupply would be an 800 Watt model. There are many good PSUs out there, please do have a look at our many PSU reviews as we have loads of recommended PSUs for you to check out in there. What could happen if your PSU can't cope with the load is:

  • Bad 3D performance
  • Crashing games
  • Spontaneous reset or imminent shutdown of the PC
  • Freezing during gameplay
  • PSU overload can cause it to break down

Let's move to the next page where we'll look into GPU heat levels and noise levels coming from this graphics card.
