Depends, it’s all a gamble. Think of it like this … how much do you spend on your kit? A top end GPU is $1500 USD. A decent surge protector might cost $15. However suppose you cheap out and get one for $9.99…then a surge blows thru it and smokes your mobo&gpu. how much did that $5 in savings cost you?
there is quite a bit that goes into it. And yet it’s not magic. Also, protection does wear out as load & surge is applied. So it’s not really worth it to pay top end, over and over, at least imo.
