Gigabyte Radeon R9 270X OC Video Card ReviewMon, Dec 02, 2013 - 4:29 PM
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 three games at 1920×1080 and averaged the peak results seen on the power meter.
Power Consumption Results: The entire platform with the Gigabyte R9 270X 2GB OC installed was consuming 109 Watts at idle and hit a maximum of 319 Watts when gaming. These are pretty good power numbers and are what we expected to see from this card, so no big shock or anything here.
