So this is a calculated value, albeit a very good one.Ībove, a chart of relative power consumption. Subjective obtained GPU power consumption = ~92 Wattsīear in mind that the system wattage is measured at the wall socket side and there are other variables like PSU power efficiency.System Wattage with GPU in FULL Stress = 202W.Measured power consumption GTX 750 Ti card Subjective obtained GPU power consumption = ~ 76 WattsĬost per Year 5 days week / 4 hrs day / €Ĭost per Year 5 days week / 4 hrs day / $.System Wattage with GPU in FULL Stress = 186W.We'll be calculating the GPU power consumption here, not the total PC power consumption. Next to that we have energy saving functions disabled for this motherboard and processor (to ensure consistent benchmark results). This setup is overclocked to 4.60 GHz on all cores. Our test system is based on a power hungry six-core Intel Core i7-3960X Extreme Edition Sandy Bridge-E based setup on the X79 chipset platform. The before and after wattage will tell us roughly how much power a graphics card is consuming under load. We simply stress the GPU, not the processor. The methodology: We have a device constantly monitoring the power draw from the PC. Let's have a look at how much power draw we measure with this graphics card installed. No further configuration is required or needed. Don't forget to connect your monitor, you can now turn on your PC, boot into Windows, install the latest compatible NVIDIA GeForce Forceware driver and after a reboot all should be working. So preferably the PEG headers should come directly from the power supply and are not converted from 4-pin Molex peripheral connectors. Once the card is installed and seated into the PC, we connect the 6/8-pin PEG power connectors to the graphics card. Preferably your power supply is compatible, most high-end PSUs built after the year 2008 have these connectors as standard. Installation of any GeForce graphics card is really easy.
