Im using an r7 370 and an a8 7600. Looking to buy a new PSU ( on a budget ) and I'm thinking of getting either the CX430, the VS450 or VS550, an EVGA 500w 80plus as seen here ( http://www.evga.com/Products/Product.aspx?pn=100-W1-0500-KR ). Appreciate any help choosing the best part, any new reccomendations are welcome but im trying to stay in the 50$ price range!
