i searching for 500,600 w psu for 50 dollars and these look ok cuz its 80 plus and have protections
When it comes to power supplies, you do not, and I repeat
DO NOT want something only "looks OK". You want to make sure that you're getting a good unit. Don't skimp, compromise or buy an off brand. You want a name brand PSU. If you haven't heard of the brand, don't touch it with a 10 foot pole.
