Power Consumption Test

 

 

Using our PROVA Power Analyzer WM-01 or "Power Thingy" as it has become quickly 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 graphics cards installed. Keep in mind; 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 in particular tests the power being drawn as much as 10% more. We test at the exact same stage every time; therefore tests should be very consistent and accurate.

 

The other thing to remember is that our test system is bare minimum - only a SSD hard drive 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, the draw is going to be higher.

Power draw is up on the PowerColor PCS+ HD 7970 as you'd expect coming in at 550 watts.

 

If you're buying a video card like this, though, you should own or at least be buying a decent power supply at the same time. We'd recommend anything in the 700 watt+ range just to make sure there's plenty of breathing room for a stable gaming PC.
