Does my PSU have surge protection or am I just misreading it.

I've got a HP Z440 PC and the manual states that the proprietary PSU is surge tolerant up to 2000V. Is this the same as surge protection? I've got it plugged into a cheap surge-protected power-board but is that even necessary with this PSU?

Does my PSU have surge protection

Most PSU built in 15 years have a form of surge protectors one way or another its about how sensitive it is and how well is it at cutting power without damaging parts.

Components that protect the equipment from surges are sacrificial (they get damaged by the spikes and would eventually fail), so to have a continuous protection against frequent spikes you gotta have a lot of them. While in a PSU there's typically just a single relatively low energy MOV. I'm not sure why but i'm gonna assume due to space constrains. Whereas in any decent dedicated surge protector there would be at least a few of those, usually with higher energy capacity, and in some also a different type of surge protection component - GDT. So if you have frequent surges and want continuous protection it would always be a good idea to get a surge protector even if the PSU has some surge protection itself too.
