All of them have black PCBs and Puro HiFi audio technology
While the Mobile World Congress was about phones and tablets, the CeBIT trade show in Hannover, Germany is more about PCs and technology in general, hence Biostar's announcement.More specifically, Biostar has officially launched three new motherboards, all of them equipped with the LGA 1150 CPU socket.
They don't have the same chipset though. While the HiFi-Z87X3D and the HiFi-H87S3+ both utilize the H87 core-logic, the HiFi-B85S2 gets the B85.
The HiFi-Z87X 3D is the so-called flagship, with four DDR3 memory slots, two PCI Express 3.0 x16 slots, a PCI Express 2.0 x16 slot (electrical x4) and three PCI Express 2.0 x1, plus 12-phase VRM to power the CPU.
Six SATA 6 Gbps ports, USB 3.0, Gigabit Ethernet, multiple video ports (DVI, D-Sub, and HDMI) and Puro HiFi 8-channel audio with OPAMP circuitry round up the spec sheet.
The second motherboard, HiFi-H87S3+, is a micro-ATX model with four DDR3 slots, a 4-phase VRM, a PCI Express 3.0 x16 slot, one PCI Express 2.0 x1 and one legacy PCI slot.
It also has similar video outputs as above, 6-channel Puro HiFi, six SATA 6 Gbps ports, and USB 3.0 plus Gigabit Ethernet.
That leaves the HiFi-B85S2. This one is a slim ATX mainboard with a PCI Express 3.0 x16 slot, a PCI Express 2.0 x16 slot (x4 electrical), two DDR3 memory slots and a pair of PCI Express 2.0 x1 slots, plus six SATA 6 Gbps ports.
As before, Gigabit Ethernet, USB 3.0, three display outputs and Puro HiFi audio technology (6-channel) are present and accounted for. Sadly, Heise.de did not have any pricing or availability details.
For those that don't understand what is so special about Puro HiFi, the audio technology uses special hardware components instead of relying on software to artificially boost quality. A whole web page dedicated to it can be found here.
