We always use meanwell power supply's with batt pack
in 10 jears time on a network with 5000 wireless devies and 800 mikrotiks and we had like 12 mikrotiks broken for no reason. , at the moment we use mikrotik for routing, 87% of the wireless hardware is from a other brand.
and +- 40 mikrotiks did go broken beqause of water, lightning, .... we replace never old hardware , only if its realy old and if the site is growing.
if we replace a backbone router , then it will be re-used on a end point.
We use RB493, omnitik, RB2011, Groove, CCR, CRS, RB433, RB951, ..... the omnitik does broke more often than the 493 with lightning, in this case 1 or 2 ethernet interfaces stop working.
So if the powersupply is good , you will never have problems with mikrotik.
from our 400 meanwell power supply's there untill now not one broken , even after a lightning storm.
fake meanwell power supply's (other brand, same shape) do go broken in 2-3 years
