Cons: none so far
Other Thoughts: Did not get full speed at first, turns out my USB3.0 drivers were not installed.READ FULL REVIEW
Pros: Works from 10V to 14.5V DC input voltage range. With Prime95 running, the system reset below 9.8V and above 14.6V DC. It's possible to use this board with 12V lead acid battery directly, but top charging voltage has to be limited to below 14.5V with some margin.
Tested with i3-4310. Idle power at 12V = 10.5W (no fan, no HDD, only SSD, win7). At 19V idle power = 12W. Full CPU load = 42 - 46W.
Be aware that internal 12V rail has 1.5V drop below input voltage. So, at 10.5V in, the rail measures 9V instead of 12V. This may negatively affect any accessories needing 12V to function, like 3.5" hard drives (not tested).
Cons: Runs CPU fan too fast, no option in BIOS to slow it down. I used external DC regulator to control fan input voltage. Poor manual documentation.
Other Thoughts: Using this with 2 monitors in Win7 for general home desktop use. Replaced my 85W desktop. The whole system (~$500) will pay for itself in energy savings in 7 years.READ FULL REVIEW
Pros: Great graphics for flawless youtube playback, quick web page rendering. Intel speed step is great, whole system uses only 12W DC in idle. Here is detailed power load breakdown with Gigabyte GA-H81TN thin mini-ITX board, SSD, no fan, no HDD:
H.264 1080P: 16W (~10% CPU)
Youtube 1080p: 18W
At BIOS screen: 30W (no speed step, i guess)
At 100% load: 46W
(power measured at 19.5V DC jack, not at the wall)
Cons: Runs hot internally under full load, even if heat sink is cold. This is well known issue with Haswell CPUs. Overclockers take note. I got 65C under full load. At idle it stays few degrees above room temp (20 - 22C).
Other Thoughts: Great gen purpose CPU. Laptop-like energy consumption at low load with desktop performance when needed.READ FULL REVIEW
