ATI Radeon HD 4830 Mainstream GPU
Total System Power Consumption
We'd like to cover a few final data points before bringing this article to a close. Throughout all of our benchmarking and testing, we monitored how much power our test systems were consuming using a power meter. Our goal was to give you an idea as to how much power each configuration used while idling and under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not just the power being drawn by the motherboards alone.
Although AMD rates the ATI Radeon HD 4830 with the same max board power as the HD 4850 (110W), our particular sample consumed less power at both idle and under load. AMD noted this may not be the case with every HD 4830 though, so be aware there will be differences from card to card.
