View numbers.  Joules says nothing about power consumption of a PSU.  Joules measures energy absorbed from a surge.  Potentially destructive surges are hundreds of thousands of joules.  How many joules will those older and new power strips absorb?

Your miner would easily convert a hundreds or thousand joule transient into rock stable, low DC voltages to safely power its semiconductors.  Transients that tiny are already made irrelevant by what is already inside electronics.  Your concern is a transient that is many times larger.  How many joules with that power strip absorb?

The most critical item on a power strip is its circuit breaker.  How many amps is that rated to provide?  How many amps does each miner demand?  Any decision without first learning these numbers is wild speculation resulting in a junk science conclusion.  What are the relevant numbers?

If a miner needs protection, then so do dishwasher, GFCIs, furnance, clocks, garage door opener, central air, vacuum cleaner, LED & CFL bulbs, refrigerator, dimmer switches, and everything else.  Protection (that safely absorbs hundreds of thousands of joules and remains functional for decades) should be considered.  This 'whole house' solution costs about $1 per protected appliance.

Only lights that say anything useful about AC power glitches are incandescent bulbs.  Power glitches can occur without lights on electronics reporting the anomaly.  Only a UPS would avert that anomaly.  Power strip protectors would do nothing.  Again, spec numbers define that.
