I have custom NAS unit based on Intel Atom 330 in ZOTAC IONITX-K-E motherboard. Also I have 3 3,5'' HDDs. All this staff located in CFI mini-ITX A9849 case. It has 220W power supply unit.
I want to do ugrade to Intel i3 3225 and some mini ITX motherboard. I don't need external video card and I am going to use builtin Intel HD 4000.
Will current power supply unit be enouph for i3 system? Or I need to change it to more powerfull one?
