Over half an year after its introduction, Zotac's feature-rich H55-ITX WiFi motherboard got a minor (or major, depending on your application) specification update, with the company dropping in USB 3.0 support. Making use of the common NEC controller, the board features two USB 3.0 ports on its rear-panel. The new model is thus named H55U3 WiFi. Sticking strictly to the mini-ITX specs, the H55U3 is a socket LGA1156 motherboard supporting processors with TDP of up to 95W, which translates to all dual-core Core i3, i5 processors with room for light overclocking, and quad-core Core i5, i7 with no overclocking.

Being based on the Intel H55 chipset, it supports Intel FDI, connecting processors with Intel HD graphics to display connectors that include DVI and HDMI. The socket is wired to two DDR3 DIMM slots for dual-channel memory, and one PCI-Express 2.0 x16 slot. Connectivity includes six SATA 3 Gb/s from the H55 PCH, 8-channel HD audio with optical SPDIF, WiFi b/g/n, gigabit Ethernet, eSATA, USB 2.0, and USB 3.0. The board uses ATX 24+4 pin power input. Zotac's H55U3 WiFi has started selling in China for US $118.
