NVIDIA GeForce GTX 660 Ti Video Card Review w/ ASUS, EVGA & MSI

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 measured the peak wattage used by the system while running the Dirt Showdown benchmark as this showed to be the most intense power user in our tests.

All of the cards in our test here today did well at idle speeds, within 3w of each other. It’s amazing that such a powerful system consumes so little power when not being used. Isn’t technology great?!

Under a load it’s a completely different story. The MSI GeForce GTX 660 Ti PE used the most power out of our trip of GeForce GTX 660 Ti’s by a slim margin. It was followed closely by the ASUS GeForce GTX 660 Ti TOP, with the EVGA GeForce GTX 660 Ti Super Clock being the most miserly of the group.
