System Builder Marathon, Q2 2013: The $400 Spirit Of Mini-ITX

Consumption And Temperatures

Power Consumption

As you know, we enable power-saving features on each system to best reflect real-world default power consumption and cooling performance. I also left the fan controls at their stock settings for my baseline run. In effect, I was trading off thermal performance in the interest of a quieter PC.

I don't have efficiency specifications for Antec's 150 W power supply. However, older units with the same model number were notoriously bad in this area. Regardless, under full load, the overclocked configuration pulls less than 120 W from the wall. Assuming between 70% and 80% efficiency, the power supply was only outputting between 83 and 95 W under full load. That should satisfy any concern that a 150 W PSU is insufficient for today's build.

AMD's Pitcairn and Tahiti GPUs serve up much higher performance than Cape Verde, but they're also a lot more power-hungry. December's $500 machine mysteriously suffered high GPU power use just idling on the desktop, inflating the active idle and CPU load data.

Despite Antec's small enclosure, heat is not a problem for us. The components I'm using are efficient, airflow is decent, and the graphics card is fed cool air through a bottom vent. In warm climates, both the graphics and case fans could spin a lot faster if they're needed, though they'd be louder too. As it stands, my notes suggest this is the quietest of the last three systems I built, particularly after overclocking. Only the $650 system was loud enough to have me reaching for my Sennheiser headset during gaming sessions.

    great article. this type of look at how a low end "budget" build handles modern titles was perfect. Loved it. I think you got about the most you could hope for out of a $400 budget. Frankly i can't find a way to make something better at that price point. spot on really. nicely done.

    I do like how most of those games were "playable" on high settings at 1080p with that tiny rig... very cool.

    Nice build, makes me wonder how it would stack up to my old 4.0 GHz overclocked Core 2 Duo office PC. Which gets gamed on occasionally using its HD 6850 graphics card.

    Enjoy the $400 build. Kinda hoped for an A10-5800k build to compare to.

    250 bucks makes HUGE difference. Unlike 2500 vs 1300 systems.

    FINALLY! I agree this whole system builder was almost a fail.
    Also, I can't believe you had a SG05 and didn't build with it,it has an awesome power supply. Again,if you weren't getting a disk drive the V3+ was the smaller, higher quality case than CM 120 ( though they're finished on newegg)
    The obsession with ginormous cards in tiny places made your cases not tiny.Clearly,a more sensible build,like with a 670,would fit in a much smaller footprint.
    The lack of the FT03 Mini is a fail. It's a Mac killing case,and should've been the go to case for the $2500 build, because at that price,my case better look it.
    Otherwise I like that you were at least up to the challenge, and I applaud this last build.

    The FT03 Mini would have probably caused the $2500 PC's graphics card to overheat, or caused the graphics card to overheat the CPU. And a 670 might have worked, but then it wouldn't have been a $2500 PC. But please don't let the facts get in the way of your opinion.

    You could say that nobody should even bother spending $2500 on an ITX-based system, or that a system with ITX limitations should never be expected to provide top performance. At least those opinions would make more sense than the stuff you said above.

    My favorite of the builds. Feels congruent to me in that budget, form factor and system capabilities all align to each other and to my personal sensibilities. I could see making a system like this for a bedroom or den.

    Or even an office! Really. I might not build one of these for a performance competition, but it looks like a solid alternative to my retired-gaming office PC.

    Some improvements I would like to suggest , Maybe I am crazy , but felt I should do this.

    Even this diminutive little machine would significantly outpace my old Phenom II X3 710, XFX HD 4830 and 4x1GB DDR2-800 (4-4-4-12) for a pretty decent price.
