help me power surge detected. my cpu turning off while i play Dota2 or LoL i see my psu 580w PLS HELP

Brand and model say little. Quality is defined by manufacturer numeric specification. Most who select supplies have no idea how to read those numbers. So hearsay and popular urban myths are used.

For example, power supplies are not damaged mostly by surges. A destructive surge might occur maybe once every seven years. Power supplies fail due to manufacturing defects. A supply manufactured with a defect a year plus ago may fail today.

Hearsay also says heat is destructive. Heat is a diagnostic tool used to find a supply when it still worked but was defective. Every good supply is happy even in a 100 degree room. But defective supplies that work at 70 degrees F can fail at higher temperatures (ie 90 degrees F). Heat did not cause damage. Heat simply identifies defective hardware that will fail at 70 degrees years later.

If a supply is reliable, then it will come with a full long sheet of specification numbers. Since most computer assemblers do not know how electricity works, then many supply manufacturers will dump supplies that are missing essential functions. For example, all supplies must contain circuits so that a failing supply will never damage a motherboard and so that a failed motherboard cannot damage the supply. Some supplies are missing these functions. Many assume the computer boots; therefore the supply must be OK. Nope. Read its specifications.

Many supplies are missing functions necessary to meet industry requirements such as FCC and UL requirements. No problem. Because the computer assembler (not the PSU manufacturer) is responsible for meeting those requirements. Many if not most computer assembler do not know they are responsible. Do not even know what those requirements are. Just another way to increase profits. Sell a supply missing functions to a market of electrically naive computer assemblers.

OEM supplies are provided by manufacturers who meet those requirements. But you would never know from so many who make recommendations and yet are learning of above engineering concepts for the first time.

If the supply does not come with a long list of numeric specifications in writing, then assume the worst. Supplies that forget to provide numbers are then not criticized by the fewer who actually know this stuff. Another technique used successfully to dump inferior supplies in the market. Demand those spec numbers even if you do not know what they say.
