AMD R7 260X - On your average system the card requires you to have a 450 Watt power supply unit.

Here is Guru3D's power supply recommendation: 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.

So this is a calculated value not a precise measurement, albeit a very good one.Ībove, we have a chart of relative power consumption. Mind you that the system wattage is measured at the wall socket side and there are other variables like PSU power efficiency.

Subjective obtained GPU power consumption = ~ 241 Watts.

System Wattage with GPU in FULL Stress = 350W.

Subjective obtained GPU power consumption = ~ 113 Watts.

System Wattage with GPU in FULL Stress = 221W.

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 unless you like to tweak the settings, for which you can open the Catalyst Control Center.

Once done, we boot into Windows, install the latest ATI Catalyst drivers and after a reboot all should be working. Preferably get yourself a power supply that has these PCIe PEG connectors native (converting them from a Molex Peripheral connector anno 2012 we feel is a no-go).

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. Installation of any of the AMD Radeon cards is really easy.
