Does anyone have the details on the power supplies that come with the PBXact 400 units? I am trying to size some battery backup options and can’t find the exact wattage and amperage on the power supplies that come preinstalled in these units.
I’ve found the technical specs for the units but all they list is voltage:
But that is probably overengineered, especially after the disks have spun up, so, if you don’t want to overengineer the backup, you probably need to measure actual demand.
That will only give the peak demand of the processor, and exclude other components. If sizing batteries, the average demand of the system will be more important.
Designing on the peak would likely cover the additional “cost” of the other components. The SSD is going to be about 5V 1.7A (x2), the 8GB DDR4 RAM will be about 1.5V 3.3A. The OP could hook the system up to a power meter and monitor that for a period of time.
Yea, hooking up a system to a power meter was the fallback plan but because all of our 400s are in production that wasn’t going to be too convenient to do so I was hoping that somebody else already did the work.
