NVIDIA GeForce GTX 285 in Tri-SLI Tested - Power Consumption Tests

We pack three GTX 285s into our test bed and see how Tri-SLI is running these days with the latest NVIDIA card.

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 7,200RPM SATA-II single hard drive is used without CD ROM or many 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.

It doesn't come as any surprise that the more graphics cards we add, the more power is needed. A Tri-SLI setup us tipping almost 700 Watt at load, while a SLI one is just over 500 Watt. The idle wattage also jumps up as we add another card into the mix.
