Sapphire Radeon HD 6990 4GB Video Card in AUSUM Mode - Power Consumption Tests

We flick Sapphire's HD 6990 4GB over to AUSUM mode, close our eyes and power on the system. We've survived to tell you about the extra grunt on offer!

Power Consumption Tests

 

 

Using our new 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 does indeed jump up a little which is no surprise since we're dealing with more voltage on the core, but the number isn't too worrying at a bit over 500 Watt. It's nothing a good 750 Watt power supply won't handle.
