Have a multiple monitor setup and the new monitors kept turning off randomly for no apparent reason. They just turn off for a few seconds, then turn back on. Bought a UPS and powered the monitors through it, and the flickering stopped.
I presume it means the power supply as-is either has over/under voltage fluctuations. So the question is whether more expensive electronics like desktops, laptops or NAS may be affected.
So far the power fluctuations have not resulted in a shut down of my desktop or NAS.
Also, what is Taiwan like during stormy weather? Is one advised to unplug sensitive electrical equipment?
Been here aince 2006, and apart from a handful of blackouts never had any problem like the ones you described.
unplugging equipment is up to you, it is not a common SOP here. Wind and rain are more common problems, not lightning.
Have you measured the voltage? It sounds like voltage drops possible due to having a long wire run from the power source, or the wire is too small for the load causing voltage drops. How many monitors are you connecting?
I would suggest you to buy an ups anyway. Although you have not mentioned the expenses of the server. A decent anti power surge ups will go the long way to give you the peace of mind in any location.
Just to let you know. I run several servers of semi commercial grade. An ups ( you can buy used commercial ones) for cheap online and insert new batteries in some shops.
My PC monitor has started doing this every time my fridge on the same circuit switches on. Motors draw a large current pulse when they switch on and it can cause enough disturbance to upset (badly-designed) electronic equipment on the same supply.
Try unplugging your fridge and see if the problem goes away.
If it has an app you can get a report on the voltage directly from the UPS and see when there’s dips. Also a good idea to buy a decent surge protector to put between it and the wall even if the UPS has that capability as it’s much quicker and easier to remove/replace the surge strip than the UPS…
