TEST RESULTS
Our test system is fairly basic, featuring a Core 2 E7200, a 65W TDP mid-level dual
core processor cooled by an Arctic Cooling Alpine 7 Pro connected
to a variable DC fan controller so the fan's power draw does not come into play.
The rest of the system consists of a single stick of Corsair memory, an Asus
Blu-ray drive, a 5400RPM notebook hard drive and an OEM Seasonic 400W power
supply. The operating system used is Vista Home Premium SP1 (32-bit).

The GeForce 9300-ITX's power consumption was fairly moderate during testing,
idling at 35W and maxing out at 65W with both the CPU and GPU being stressed.
Oddly the addition of a GPU load to the CPU load barely made a difference in
power draw. Video playback was flawless as one would expect with a powerful
IGP and a Core 2 Duo processor.

The Zotac 9300-ITX was more or less on par with Intel's G45-powered mini-ITX
board, the DG45FC in
terms of power consumption. There was some slight variation during video playback,
but otherwise the two were very similar, both idling at 35W and topping out
at 65W when the CPU and GPU were put under stress. Compared to the Asus
P5N7A-VM, a microATX board using the same GeForce 9300 chipset, Zotac's
board is slightly more efficient, with a 6W improvement when idle, and 3W on
load.
WiFi
We used the board's WiFi module to download 100 MB or so of Vista updates and
it gave us a consistent 4 bars of signal strength throughout at a distance of
about 25 feet from our lab's wireless 802.11g router. We did not notice any
disconnections or other abnormalities during the brief time we tested the wireless
functionality. The module's power consumption was also very low, adding only
2W to the system's idle power consumption. By comparison, the unit that came
with Zotac's GeForce 8200-ITX WiFi
increased power draw by 5~6W. This is even more frugal when you consider that
we've seen USB 802.11g adapters burning up 10~15W.
