evga 600w b1

[ilminti0572cnfrm]

i have a low powered system that would consume a maximum of 220w of power and i was thinking should i buy a 600w psu (evga 600w b1) because its on sale or will my low power consumption cause efficiency problems to that psu

a good 450w unit > a 600w bad unit.

yes it is enough but can you get anything else? ( xfx ts, seasonic s12ii/ focus , corsair cx /tx )
