Is there something like this in the market? Input 12-24V DC (actually anything in this range will do) Output 12V,5V,3V (am i missing anything?) about 65W total load, ALSO, i would like if this powersupply could charge (drip?) a 12v SLA (sealed lead acid), and be able to use this 12v battery for emergency power? This is in everyway similar to what a laptop does, but for a desktop, the peak power rating should not be a problem, as planning on running this with A64 2X 3600+ EE, and with laptop HDD and no optical drive. Does anyone know anything similar?
