Power Consumption Test
Using our PROVA Power Analyzer WM-01 -or "Power Thingy" as it has quickly become known as to our readers- we are now able to find out what kind of power is being used by our test system and the associated video cards installed. Keep in mind that it tests the complete system (minus LCD monitor, which is plugged directly into AC wall socket).
There are a few important notes to remember, though. While our maximum power is taken in 3DMark06 at the same exact point, we have seen the power being drawn as much as 10 percent more in particular tests. We test at the exact same stage every time, so tests should be very consistent and accurate.
The other thing to remember is that our test system is bare minimum -only a SSD is used, with a single CD ROM, and minimal cooling fans.
So, while the system might draw 400 watts in our test system, placing it into your own PC with a number of other items will result in a higher draw.
Power draw numbers are nearing the top, with a little over 800 watts being seen at load. This is quite high, and for something like this we'd really recommend that you're purchasing a quality PSU around the 1000 watts mark to make sure you're completely covered.
