It's model number is SSR-750FX 80+ gold.Previous PSU was deepcool da600 i believe. I live in bulgaria so i cant really give you a site to shot as i pretty much have to search for what i am looking from across many stores. I don't know if i can return it and buy a new one as some time has passed. If that is the problem tho you can recommend a psu and i can look for it.
