Power consumption
We measured system power consumption, sans monitor and speakers, at the wall outlet using a Watts Up Pro power meter. Readings were taken at idle and under a load consisting of a Cinebench 11.5 render alongside the rthdribl HDR lighting demo. We tested with Windows 7's High Performance and Balanced power plans.

Motherboard makers usually ship their boards with energy-saving features that promise to lower power consumption without resorting to CPU throttling that might hinder performance. We've tested the Asus, Gigabyte, and MSI boards with their power-saving features enabled and disabled. The Intel and Zotac boards aren't equipped with such features, so they've been tested only with Windows handling power management.

Obviously, the H67-ITX consumes a lot less power when you remove the Radeon HD 5870 that's serving as our discrete graphics card. With the Radeon installed, the Zotac board registers the lowest idle power draw of the pack. Cranking up a combined CPU and GPU load changes the picture a little, sending the H67-ITX to the back of the class with the most power-hungry P67 configs.

Motherboard peripheral performance
Our last stop on the testing front is the wonderful world of onboard peripherals. Here's how the H67-ITX's most important ports perform:

Zotac H67 164.7 163.9 55.5 3
Zotac H67 (IGP) 160.5 162.7 55.9 3

The board's Via USB 3.0 chip may have twice the ports of the NEC silicon on the others, but each of those ports appear to be a little bit slower. At least there's no performance lost when switching to the IGP.

Zotac H67 (IGP) 37.5 33.7 24.1 1

Although its USB 3.0 performance was a little slower than what we've seen from other boards, the H67-ITX's USB 2.0 performance is more competitive.

With a mechanical VelociRaptor hooked into one of its 6Gbps SATA ports, the H67-ITX offers faster disk subsystem performance than some of the P67 offerings.

Things look good when we switch to a RealSSD C300, as well. The Zotac board isn't the fastest option on the block, but it's right in the middle of a pack of P67-based desktop offerings, which is a very good place to be.

We have it on good authority that Realtek's standalone Gigabit Ethernet controllers are cheaper than what it would cost to tap the GigE MAC built into Intel's recent chipsets. It's good thing the Realtek chip on the H67-ITX offers plenty of throughput with low CPU utilization.

Given the cramped nature Mini-ITX mobo layouts, it's no surprise that the H67-ITX scores a little lower than the full-sized ATX competition in RMAA's test of analog signal quality. Having components so close together surely generates more board-level noise than spreading things out. Here, and throughout our peripheral testing, we see little difference between the H67-ITX's performance with and without a discrete graphics card installed.
