Power consumptionMeasurements were taken at the wall socket: This is therefore the total power consumption of the power supply, in this case a Cooler Master Real Power PRO 1250 watts.
Although the Radeon HD 4770 is not especially economical in idle, without being overly demanding either, it has relatively low energy consumption in load.
Noise and temperature levels
We measured sound levels at rest and sound levels after 30 minutes in load.
The Radeon HD 4770 stock card is a quiet card, but is it well cooled? The GPU sensor gives a reading of 58 °C in idle and 73 °C in load, we can therefore reply in the affirmative.
We observed this in more detail with thermal imagery:
