ASUS ARES II review

Installation of any of the AMD Radeon 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 native (converting them from a Molex Peripheral connector anno 2013 we feel is a no-go).
Once done, we boot into Windows, install the latest ATI Catalyst drivers and after a reboot all should be working.
Mind you though that in the Catalyst Control panel you'll need to activate Crossfire mode. Even with one card (2 GPUs) you need to Enable AMD CrossfireX mode. Obviously with two cards installed, 4 GPUs need to be selected and activated.
No further configuration is required or needed unless you like to tweak the settings, for which you can open the Catalyst Control Center.
You have to love the LEDs that show clearly if you didn't connect a power cable properly.
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 simply stress the GPU, not the processor. 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 a power hungry Core i7 - X58 system. This setup is overclocked to 3.80 GHz on all cores. Next to that we have energy saving functions disabled for this motherboard and processor (to ensure consistent benchmark results). On average we are using roughly 50 to 100 Watts more than a standard PC due to higher CPU clock settings, water-cooling, additional cold cathode lights etc.
We'll be calculating the GPU power consumption here, not the total PC power consumption.
Measured power consumption single ASUS ARES II
- System in IDLE = 172W
- System Wattage with GPU in FULL Stress = 642W
- Difference (GPU load) = 470W
- Add average IDLE wattage ~20W
- Subjective obtained GPU power consumption = ~ 490 Watts
Measured power consumption two ASUS ARES II cards in Crossfire
- System in IDLE = 212W
- System Wattage with GPU in FULL Stress = 1123W
- Difference (GPU load) = 911W
- Add average IDLE wattage ~40W
- Subjective obtained GPU power consumption = ~ 951 Watts
Mind you that the system wattage is measured at the wall socket side and there are other variables like PSU power efficiency. So this is a calculated value, albeit a very good one.
But yeah with two ARES II cards installed I had a WTF moment as we pushed well over a kilowatt. The photo above isn't even showing the maximum power draw we measured just yet. But roughly it's 250 Watt per utilized GPU.
Above, 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:
- ASUS ARES 2 - On your average system the card requires you to have a 800~850 Watt power supply unit.
- ASUS ARES 2 Crossfire - On your average system the cards require you to have a 1200~1350 Watt power supply unit as minimum.
If you are going to overclock your GPU or processor, then we do recommend you purchase something with some more stamina.
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 would happen if your PSU can't cope with the load:
- 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.
We test and review the ASUS ARES II as single card and in Crossfire today. The ARES 2 is a dual-GPU Radeon HD 7970 graphics card. Fully customized with 3rd party Liquid cooling. We test the product one one and three monitors in Eyefinity with the hottest games like Battlefield 3, Sleeping Dogs, Far Cry 3, Medal of Honor Warfighter, Hitman Absolution and many more.
ASUS ARES Review
We test and review the worlds fastest single Graphics card. These uber-high-enthusiast targeted products are intended to create a lot of buzz and potentially have a lot of marketing value. But face fact is also that there is a small group of end-users actually really interested it in, regardless of price and deficits. So with this round of realizing something fun, extra ordinary and sure prices very steep ASUS went back to the drawing board. They came up with a dual-GPU design solution based off Radeon 5970, but an overall better design, new PCB, higher clock frequencies on GPUs and more memory (2GB per GPU). Then they threw improved voltage regulation management into the mix and added a new cooler with the weight of a small baby on top of the GPUs to deliver something really special.
