If it were good for its label, yes (i.e. a "real" 450W PSU would be sufficient, although it also depends on your graphics card). As noted, Zebronics is a very low quality device, something I'd call a "PSU-shaped object." It might be good for half its label, and even that may be out of spec. It will lack filtering components, and is the sort of unit that dies for no apparent reason, and often takes other parts with it into the fiery abyss.
