Mini-ITX Bay Trail board sips DC power

In April, ASRock introduced a Mini-ITX motherboard with a quad-core Bay Trail processor. The Q1900B-ITX relies on traditional ATX power, and it now has a sibling primed for DC input. Say hello to the Q1900DC-ITX, which looks even more appealing than its ATX counterpart.

This specimen is compatible with 9-19V DC power bricks, allowing it to slip inside extra-small cases that lack internal PSUs. Support for DC input is also handy for automotive PCs and other, more esoteric applications. ASRock doesn't provide a DC adapter, though. Users will have to supply their own.

Apart from the power config, there are a few other differences between this model and its ATX counterpart. The DC version has six analog audio jacks instead of three, and it uses a fancier Realtek codec chip. It also features a ASMedia storage controller that kicks in two 6Gbps SATA ports to complement the dual 3Gbps ports in the Bay Trail SoC. Another ASMedia chip adds more USB 3.0 connectivity, bring the total number of SuperSpeed ports up to four (two at the rear and two via an internal header).

As icing on the cake, the Q1900DC-ITX sports a Mini PCIe slot suitable for wireless cards. It retains the PCIe x1 slot from the ATX model, too, and it features the same Celeron J1900 processor and dual SO-DIMM slots.

The DC version is clearly more well-rounded than the standard board. There's no word on pricing, but expect to pay a premium over the ATX alternative, which is selling for $75 right now. Thanks to FanlessTech for the tip.
