VGA Power Consumption
Life is not as affordable as it used to be, and items such as gasoline, natural gas, and electricity all top the list of resources which have exploded in price over the past few years. Add to this the limit of non-renewable resources compared to current demands, and you can see that the prices are only going to get worse. Planet Earth is needs our help, and needs it badly. With forests becoming barren of vegetation and snow capped poles quickly turning brown, the technology industry has a new attitude towards turning "green". I'll spare you the powerful marketing hype that gets sent from various manufacturers every day, and get right to the point: your computer hasn't been doing much to help save energy... at least up until now.
For power consumption tests, Benchmark Reviews utilizes the 80-PLUS GOLD certified Corsair 850W PSU, model TX850W. According to Corsair, this PSU provides 80% efficiency, however our results are not adjusted for consistency. To measure video card power consumption, Benchmark Reviews uses the Kill-A-Watt EZ (model P4460) power meter made by P3 International.
Normally, we would like to take a baseline test without a video card installed in the test system. However, in this test system, the on-board Radeon HD 4290 will auto-enable, even if previously disabled, if there is no other video card present. This poses a problem to getting a baseline for power consumption, so for this article, we will only be showing the power consumption of the system with the video card at idle, and at load. This should let us know how much power the video card can consume. Remember that this test is relative, since more power is consumed by other system components during the FurMark stress test as well. It should show us, however, a good idea of how much total power could be consumed in a media style PC under the harshest of circumstances.
ASUS ENGT430 GeForce GT 430 Video Card Power Consumption
The idle test results are taken while the system rests idle at the Windows 7 login screen. Then we load up FurMark and run the stress test and record the load power consumption after the test has been running for about 10 minutes.
The ASUS ENGT430 does not require any power connection from the PSU. This alone seriously limits the ENGT430's capacity for power consumption. Without any extra power, the max load of the ASUS ENGT430 is 75W. When are test system was running at idle, it consumed 68W of power. That's not much. With FurMark stressing the ASUS ENGT430 to the max, the system drew 147W of power. Remember that these numbers are full system power. While that isn't the maximum amount of power that we can expect this system to draw, due to the fact that FurMark stresses mainly the GPU, it will certainly be on the higher end of the system. This is good news for HTPC users. Many of the PSUs that come with, or fit in, mini-ITX cases are around 200-300W. Some are even less. With an entire system running only 147W of power during GPU stressing, it appears that the ENGT430 is a good choice for an HTPC and it is well suited for anyone watching their power consumption.
