There is an option called Anti Surge Support in my BIOS setup. The user manual of my ASUS H87I-PLUS motherboard gives no explanation on it, and I can't get exactly what it is after googling. Could you please tell me simply: what is it used for, or under what circumstances should I enable that option? It is disabled by default.
My rough understanding is, surge happens when voltage supplied is unstable, and a sudden increase of voltage causes a surge. Am I right?
Is there any side effect enabling it regardless whether need it?
