Diamond AIW5000 Power Consumption
If you're going to build n HTPC that will remain powered 24/7then power consumption will be a big issue.We can already predict that the HD5570 included with the AIW5000 will have more power consumption than the ATI factory standard card. It got the same marks and produced more heat, and that energy has to come from the outlet.
To measure isolated video card power consumption, Benchmark Reviews uses the Kill-A-Watt EZ (model P4460) power meter made by P3 International. A baseline test is taken withouta video card installed inside our computer system, which is allowed to boot into Windows and rest idle at the login screen 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 login screen. Our final loaded power consumption reading is taken with the video card running a stress test using FurMark. Below is a chart with the isolated video card power consumption (not system total) displayed in Watts for previously tested products:
* Results are accurate to within +/- 5W.
The HD5570 test system used 64W at idle without a video card. The power consumption values are recorded in the table below.
The ATI factory model only pulled 12 W at idle and 52 W under a load. Even though we anticipated this result it is still drastic; double the power consumption. I'm not too excited to use this exact card in a PC that will be on day and night. But all things are relative. Twenty watts isn't so large a drain that it will even be obvious in my monthly budget. After all, it only takes 4 hours of SLI gaming to use the same amount of daily energy.
