Surge protector

Wondering if my surge protector is good enough. It says 3ka and 500v on the back. What do these numbers mean? Is this good enough to protect my PC?

Only ups devices can protect pc, simple surge protection are useless.

Blatantly incorrect. A surge protector will protect a pc from surges. A UPS will protect from surges, brownouts, and noise. A surge protector is still very usefulz

As far I known, overvoltage/overpower protection are in almost any newer pc psu. Biggest problem are voltages flustration from max to min, that can make alsot any psu defects and surge protection not protect from that. Only ups protect from almost all power problems.

Dude... Overvoltage and overpower protections in PSU are on low voltage side.

Dude... Noone psu will protect your pc 100%, yes they have many protections, but that's can be not enough, therefore only ups can protect your psu/pc by 100%.

To simplify, a surge protector will protect you if the voltage is too high, UPS will also protect you if the voltage is too low.
Low voltage cannot damage your components, but sudden shutdown can corrupt your data. This is what UPS is for.
Most cheap UPS are the "offline" type, which means they are basically surge protectors with backup power attached.

3ka means 3000 ampere
Lets just say i dont trust a simple plugin surge protector with a direct lightning hit (a trained electrician explained me some stuff years ago) But for the usual stuff it should be fine.

I second this. Plug-in SPDs (also known as Type 3's) are not designed to handle a lightning strike. (They should be called surge diverters as well, not protectors, but I suppose the latter sounded better for marketing.) PSUs themselves also already have MOVs (the little round devices that do all surge protection in a Type 3 device), so they have their own basic form of protection.
OP should invest in a Type 1 or 2 device for their household, which will handily outperform a plug-in strip if protection is so desired.

I’m not worried about lighting strikes. I unplug my cable electronics when there is a thunder storm(not often).

Right. Those are just power strips that add more outlets to a socket. Best I've had is the TrippLite Isobars. Those are basically industrial grade. They also include some insurance for damages.
