AMD Radeon HD 7990 6GB Dual GPU Video Card Overclocked - Power Consumption Test

AMD Radeon HD 7990 6GB Dual GPU Video Card Overclocked

We've tested the new AMD Radeon HD 7990 dual GPU beast with its out of the box performance, and now we see what happens when we overclock it. (NYSE:AMD)

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.

As you'd expect power draw is up at both load and idle. It's nothing too major, and like we've mentioned a few times now, if you're using a video card like this, you should own or be buying a decent quality, high-wattage power supply at the same time.
