i am building a low to midrange computer and im not sure which power unit to use either the SeaSonic SSR-650RM 650W or the Rosewill CAPSTONE-550-M 550W. Both are semi modular and are 80 plus gold certified. I have been looking at both of their specs and reviews but still not sure
any advice would help, thanks
