Anet A8 3D Printer Upgrades: 12V Power Supply From a Server

This is the first upgrade for the Anet A8 3D printer. A new powersupply from a HP server will be a fire-hazard reducing upgrade compared to the original undersized and over-specified power supply that came with the printer.

12V @ 62A is of cause much more powerful that needed for the printer, but this will keep the fan spinning at minimum speed. You do not want to be in the same room as a server power supply running at full current output with maximum fan spin. It is like a jet engine.

Below is the schematic for a HP DPS-750RB Rev. A server power supply, standard model number HSTNS-PD18.
