Power Consumption And Temperatures

Power Consumption

We enabled power saving features on both rigs and deliberately chose not to override automatic controls. The benefit, of course, is that we enjoy lower temperatures, less heat dissipation, and a quieter fan. On the other hand, some folks argue in favor of turning power-saving features off to maximize performance.

The current build’s 50.2 W power consumption at idle and 77.6 W under full CPU load is quite amazing. Less impressive are the power results when we apply a full 3DMark 11 load to the graphics subsystem.

Temperatures

While the performance of Intel’s retail boxed heat sinks isn't impressive, they both delivered adequate cooling at stock frequencies, operating quietly at the same time.

GPU temperatures may look high, but we had cooling to spare in both systems. Even overclocked, the GeForce GTX 560 Ti’s fan peaked at 54%, while the Radeon HD 6950’s duty cycle never broke 39%.

    It is just incredible how well the G530 performs in gaming.

    Would have liked to see Diablo 3 and SC 2 benchmarks for this build.

    why are you not increasing the voltages on the GPU to get more clocks ?
    any enthusiast with limited budget would want to maximize his core clocks with higher voltages.. the card can keep cool by increasing the fan speed.
    More noise for a gaming session is acceptable.

    Dumping the bulk of our funding into graphics is sure to spell disaster throughout the media encoding and productivity benchmarks. But it's time to face the music.

    pun intended ? ;)

    Celeron G530 is what I'm rocking in my gaming rig. It is definitely a capable processor, surprising given the legacy behind anything labeled Celeron.

    Slomo4shOWould have liked to see Diablo 3 and SC 2 benchmarks for this build.I can't give you exact fps rates, but my machine is very similar to this one (only difference is the GPU: 6950+Z68) and I get similar frame rates in all the tested games. So I'll infer to you what this rig would probably get close to.

    Diablo 3 maxes out at 60fps with occasional dips down to ~30fps when getting mobbed on hell. As for SC2, frame rates for me tended to be around 35fps on average with everything maxed out at 1920x1080 for both games.

    s3anisterCeleron G530 is what I'm rocking in my gaming rig. It is definitely a capable processor, surprising given the legacy behind anything labeled Celeron.Ah, but think way back.... slot 1, 440BX, and the Celeron 300A? I had a 266@412MHz, a 300A@464MHz, a 300A@450MHz, and a 333(that topped out down at an 83 MHz FSB).

    While not the first chips I had overclocked, those slot 1 Celeron's gave me the incurable OC bug! *dreams of G530K*

    Amazing! I never thought an SBM machine would ever come this close to my own rig. And confirm for me that my drooling over $200+ graphics cards is not an impractical fantasy for my current rig. I've been dreaming of retiring my old GT240 for a newer card and had the HD7850 (or comparable Nvidia counterpart when it comes out) in mind, or even an HD7770. I now feel justified and my wife will go nuts over the pc part purchase, again.

    I did notice one thing when I compared this build with my system - mine idles at 48-52 watts, too, and I use a 500W S12II. I think right-sizing the PSU will add to the efficiency. A 350w PSU is my bet for bringing the idle power draw closer to the 20% mark of the PSU rating where efficiency starts to pick up (as per 80plus requirements). I say 350w because whoever gets this will likely want to upgrade the CPU to something beefier sooner or later. Nah, sooner!

    Thanks, Paul! for tackling love and system-building with reckless abandon.

    i got a question. if I were to use a phenom 2x4 965 BE(3.4ghz) for a gaming rig on a similar budget to this, would it bottleneck me in gaming and other applications?

Dealing with fixed CPU clocks and memory frequency, I just haven't been too aggresive with previous efforts with Radeons, and thus didn't want to boost voltage here with the GTX. Trying to play it fair, that's all. Maybe once we revisit overclockable platforms, and are already dealing with increaded noise, I'll get itchy to max-out the GPU.

    Thanks for the feedback though. I'm actually surprised given the balance of the system, that people would desire to see aggressive GPU overclocking.
