I have had one of the industrial machines here crap it's power supply. It's a Dell XE and of note, the power supply has a 3A supply of 24.8v as well as the standard (but miniaturized) ATX / SATA / etc connectors.
It's out of warranty (of course) and the responsible department have not paid maintenance on the equipment that the PC was embedded in (of course).
I will probably just chuck in a new PC and have the machine vendor come out and configure it at T&M rates.. But it's a tight fit, and I will need to hack in a remote power on / off button and run a serial port off USB.
Does anyone know what this 24.8v rail is for exactly? Aside from this, the PC looks standard in every way.. No special cards, no special i/o ports, single motherboard with 2 PCI and 3 PCI-E slots, single HDD and single DVD… One external fan connector at 12 volts.
Just google the part number and look on Amazon. Should be details on the side of the unit.
Industrial units usually have beefed up rails to supply additional power for higher RPM fans (as typical of servers) and probably SATA power connectors. So most likely that extra power is used for fans, peltier coolers, drives and such.
