Power Consumption and Temperatures

Video Card Power Consumption

For power consumption tests, Benchmark Reviews utilizes an 80-Plus Gold rated Corsair HX750w (model: CMPSU-750HX). This power supply unit has been tested to provide over 90% typical efficiency by Ecos Plug Load Solutions. To measure isolated video card power consumption, I used the energenie ENER007 power meter made by Sandal Plc (UK).

A baseline test is taken without a video card installed inside our test computer system, which is allowed to boot into Windows-7 and rest idle at the desktop before power consumption is recorded. Once the baseline reading has been taken, the graphics card is installed and the system is again booted into Windows and left idle at the desktop. Our final loaded power consumption reading is taken with the video card running a stress test using FurMark. Below is a table with the isolated video card power consumption (not system total) displayed in Watts for each specified test product. The HIS Radeon R9 280 IceQ X² OC 3GB Video Card requires 1x 6-pin and 1x 8-pin power connectors from your PSU. The power consumption results discussed below are absolute maximum values, and not representative of real-world performance.

Power Consumption

Power State Power Consumption (watts)
Idle Desktop (no video card) 42w
Idle Desktop 20w (62-42)
FurMark Load (extreme burn-in) 191w (233-42)

Video Card Temperatures

Benchmark tests are always nice, so long as you care about comparing one product to another. But when you’re an overclocker, gamer, or merely a PC hardware enthusiast who likes to tweak things on occasion, there’s no substitute for good information. Benchmark Reviews has a very popular guide written on Overclocking Video Cards, which gives detailed instruction on how to tweak a graphics cards for better performance. Of course, not every video card has overclocking head room. Some products run so hot that they can’t suffer any higher temperatures than they already do. This is why we measure the operating temperature of the video card products we test.

To begin my testing, I use GPU-Z to measure the temperature at idle as reported by the GPU. Next I use FurMark’s “Burn In test” (with extreme burn-in enabled) to generate maximum thermal load and record GPU temperatures at high-power 3D mode. The ambient room temperature is also measured throughout testing. FurMark does two things extremely well: drive the thermal output of any graphics processor higher than applications of video games realistically could, and it does so with consistency every time. Furmark works great for testing the stability of a GPU as the temperature rises to the highest possible output. The temperatures discussed below are absolute maximum values, and not representative of real-world performance.

Ambient temperature 27.5°C

Fan Speed Temperature °C Noise level /10
Idle 20% 38 1/10
Load 45% 74 3/10
Load 100% 68 8/10


The HIS Radeon R9 280 IceQ X² OC 3GB Video Card ships with a factory overclock out of the box and there really is very little overclocking headroom remaining. While HIS haven’t pushed this model to the absolute limits of its capabilities, I could only pry out 60MHz extra core clock and 50MHz extra memory clock. These overclocks really didn’t do much to improve the benchmark results so they were disregarded. Temperatures and power consumption are also high enough with the factory overclock already without trying to squeeze out more performance.

That’s all of the testing over, in the next section I will deliver my final thoughts and conclusion.

    If you can put 6 of them in SLI in an attached tower, …it could be pretty good.

    1. RealNeil

      I have two of them in crossfire and they ~are~ pretty good.

    2. Steven Iglesias-Hearst

      You will do very well to SLI 6 of these video cards since SLI is an NVIDIA technology, and the upper limit for multiple GPU configurations is 4.

      I expect you mean CrossFireX? And even still, going above 3x CrossFireX is utterly overkill.

    The PCB shot is the Radeon R9 270X, not the 280 IceQ X2 OC.

      Thanks for pointing that out for me Hassan. The review has been updated with the correct image.
