[SOLVED] How much power do I need?

its a redragon non modular power supply of 500 W 80+ bronze
I would be very worried about that PSU. Very little information about it and the manufacture has purposley left the specs sticker out of the product pictures. I am going to guess it's based on an old platform and has a laughably small 12v rail. Can you post a pic of the sticker on the side that shows the specs?
