Stop Freaking out!!!!!!!!!!!
Console supplies fail......CONSTANTLY. Just like anything else you throw around in your truck, or that gets bounced around in your truck, or gets exposed to varying atmospheres, humidity or just plain turn on and turn off, and lastly AGE, they break.
It's nothing to get too upset over. Supplies should be maintained like anything else. A slightly loose heat sink screw on a rack mount supply can cause mild overheating and eventual failure. The heat sink silicone dries out under the regulators
turning into an insulator allowing heat to build up blowing regulators. Bridge rectifiers simply wear out. Caps get old, start drying out demanding more current and adding hum.
Just to give you an Idea of what supply problems I ran into in last year before I stopped doing repairs, 4 Yamaha PM series supplies, 6 Soundtracs Supplies, 2 Soundtracs Solo's, 2 Allen and Heath supplies, numerous EV processors, Numerous Yamaha PCMs,
Numerous Quadraverbs, TDM crossovers, Klark Teqnique eq's, Biamp Eq's, Samson amps (all refused), the list goes on.
Get the supply fixed, while you are at it go through the console and make sure every thing is tight and clean. If it's old look for oxidized solder joints. If there are numerous problems like various sections not working (an eq here, a send there), you could also have a few bad chips drawing enough current in total to blow a supply. Once the supply is fixed make sure to find out exactly what was wrong with it. If any of it was age related,
have the other supply cleaned up too.
Good Luck.
Added. Many power supplies these days are barely rated for what they are powering so you may already be running on the edge.
