ASUS Poseidon GTX 780 Video Card Review

Power Consumption

For testing power consumption, we took our test system and plugged it into a Kill-A-Watt power meter. For idle numbers, we allowed the system to idle on the desktop for 15 minutes and took the reading. For load numbers we ran Battlefield 4 at 3840×2160 and recorded the average idle reading and the peak gaming reading on the power meter.

Power Consumption Results: Of the three NVIDIA GeForce GTX 780 Ti video cards the Gigabyte GeForce GTX 780 Ti GHz Edition card used the most power. This was expected as it has the highest clock speeds and also higher GPU Voltages if GPU-Z is reading the voltages correctly. With the Gigabyte GeForce GTX 780 Ti GHz Edition in our test system the entire system at the wall was pulling 116 Watts at idle and 512 Watts at load. The MSI GeForce GTX 780 Ti Gaming consumes 112 Watts and idle and 470 Watts when gaming. The EVGA GeForce GTX 780 Ti Superclocked w/ ACX Cooling 3GB card used 113 Watts at idle and 460 Watts at load. The small 10W difference between the cards can be explained by the GPUs having different amounts of leakage, clock speeds and cooling fans.
