This is the first time I've encountered the error message since I bought my new pc (specs http://pcpartpicker.com/p/c6JtFT)

I've read some articles about it, and I wasn't sure if I should turn off Power Surge Protection... Should I disable it or not? If something goes wrong and I somehow managed to fry the parts, is there a way to fix it?
 
Solution


Modifying the PSU would void the PSU's warranty. You would also have to know what you're doing. If you have to ask then you shouldn't be doing it.

Sell it and buy a better quality PSU.
Insufficiently sized capacitor(s) on the PSU's APFC circuit will cause problems because of insufficient hold-up time.

Insufficient hold-up time means that the PSU is less likely to properly handle very short term (< 16 milli-seconds) power fluctuations in the power grid.

The Corsair CS series are known to have insufficient hold-up time.
 


Replacing it with the same brand and model will change nothing. You won't be able to replace it under RMA because it is not considered a defect. That specific PSU model was designed and built that way due to cost constraints. Corsair targets the CS Series for basic and mid-range PCs.

The EVGA SuperNOVA 750 G2 (220-G2-0750-XR) that I recommended above. https://pcpartpicker.com/part/evga-power-supply-220g20750xr

The Corsair RMi Series RM750i (CP-9020082). https://pcpartpicker.com/part/corsair-power-supply-cp9020082na

The Corsair HXi Series HX750i (CP-9020072). https://pcpartpicker.com/part/corsair-power-supply-cp9020072

All three models pass hold-up time and transient response testing. Voltage regulation and ripple suppression are excellent on all three models. They represent some of the best 750W PSUs available.
