I would hope with that many rigs you are running quality PSUs and not some ATX garbage to power them.
Every power supply that meets ATX standard is superior to so many less robust or just as at risk appliances. What protected the dishwasher, dimmer switches, furnace, door bell, vacuum cleaner, GFCIs, dryer, toaster, LED & CFL bulbs, garage door opener, central air, and clocks? Why are those not replaced every month or year? Because all appliances (especially all power supplies that meet ATX standards) remain function for decades. How often this year have you replaced surge damaged smoke detectors?
All appliance contain robust protection. Concern is for a rare anomaly, maybe once every seven years, that might damage some. That is why informed consumers spend $1 per protected appliance for the properly and properly earthed 'whole house' solution.
Blaming the supply is too often due to not even identifying why a failure occurs. Most ATX supply failures are due to manufacturing defects - which no surge protection (not even effective and properly earthed) can avert.
ATX power supply is a most robust electrical device. Those other appliances are at much greater risk.
