What do you mean by "protection".  All power supplies have some sort of
over voltage protection and currently limiting.  Do you also want surge
protection?  Noise filtering?  As always, you only get what you pay for.

Forget those cheap "surge protector" power bars.  They don't offer much
protection.  If you want "safe" power, get a properly installed and
grounded surge protector, near your entrance panel or run through a good
full time UPS.  You can also get constant voltage transformers and many
other items.

Also, modern CPUs should throttle back or even halt, if they get to hot.
 Cleaning the dust out of a computer does wonders for cooling.  You
might also consider heat pipes, instead of fans on the CPU, as they're
far more reliable and efficient.
