Looking the pictures over, looks to be six boards with 16 chips apiece for a total of 96 chips, the same as three blades. A stock blade runs off 12MHz, with a theoretical limit of 10.752GH so three would run 32.256GH max. The V1 blades had a secondary oscillator at 14.318MHz with a limit of 12.83GH so three would run 38.49GH max. The boards in the Cube also appear to have two installed oscillators.
I'm gonna guess the Cube is 96 of their standard BE100 chips on six boards, running 12MHz primary and 14.318MHz overclocked. Two VRMs on each board, my guess is in one of two configurations. Possibly they run in parallel each powering a bank of 8 with software-selectable voltage output tied to oscillator selection, or if one runs stock 1.05V and one runs 1.20V such that when "high speed" is selected in software it automatically drives the secondary VRM and disables the primary.
If it's the case that they're the same BE100 ASICs present on Blades and USB BEs, then the power consumption is going to be the same as everything else - in the neighborhood of 250W for stock 30GH operation. Using an automotive blade-style fuse could be seen as a convenience for replacements without requiring disassembly, or because it's easier to find 20+A fuses in automotive than standard SMD or tube packaging?
The only question I have presently throwing that power estimate around, is the twin six-pin power connectors. If this is to be used with a standard ATX power supply and twin PCIe power leads, the six-pin connector is only required to supply 75W of power giving this a total intake capacity of 150W.
Looking forward to hearing more official information, and definitely getting my hands on a couple to play with.
