Re: Googles Servers I'm quite sure they don't normally exist. Google probably had these built specifically for their application.
No idea on the hard drives. Probably a cable somewhere just can't see it. |

1 edit | Look a little closer... that large red wire is going to the battery over on the right.
The entire psu is solid 12v, so more than likely that board you see right under the sata drives takes in the 12v and converts is to a pass-through 12 and 5v for the drives.
As from the article "Power supplies convert conventional AC (alternating current--what you get from a wall socket) electricity into the DC (direct current--what you get from a battery) electricity, and typical power supplies provide computers with both 5-volt and 12-volt DC power. Google's designs supply only 12-volt power, with the necessary conversions taking place on the motherboard." |

The red and black wire goes directly to the battery. The yellow and black wires go directly to the motherboard. The tiny wires coming from the power supply go directly to the plug visibly laying on the motherboard. |
