Here is a straight, South African answer to the question in the heading, with the trade-offs spelled out instead of a vague reply.
Quick Answer
Yes for the right setup; skip it if you are on a tight budget. Weigh it against the rest of your build and your real usage before spending. As a rule of thumb, only commit once the core parts are sorted and you have at least R1,000 spare for the extra.
When it is genuinely worth it
There are clear cases where it pays off: heavy daily use, a specific competitive need, or a build that is otherwise complete. Outside those, the budget tends to stretch further elsewhere.
Where the money goes furthest
Put your first rand where the difference is felt every day. A surge protector only earns its price once the parts that limit your experience are already handled, so spend on the bottleneck before the luxury.
How to decide quickly
List the one thing that frustrates you most in your current setup. If this purchase fixes that, buy it; if it only adds polish, park it until the bigger gaps are closed.
Quick recap
Keep the steps above in order, test one change at a time, and only spend money once a single cause is confirmed. For a South African build, a clear diagnosis beats an expensive guess every time.
FAQ
What should I sort before buying a surge protector?
Get the parts that limit your experience right first. A surge protector is a refinement, so it makes sense once the GPU, monitor and storage are already where you need them.
Does it make sense on a tight budget?
Only if it removes a genuine pain point. On a stretched budget, the safer move is to finish the core build first and add the surge protector later.
Is a surge protector worth it for casual use?
For light, occasional use the gain is small, so the money usually stretches further on a core part. It earns its keep mainly under heavy or daily use.
