No. Stick with Corsair, Seasonic, PC Power and Cooling, XFX, Silverstone, Enermax, OCZ and Antec. You should be able to find a unit from one of those brands for close to the same price as a junk brand like Logisys.
no, absolutely not. Its probably powerful enough to run the components selected, but it will blow up within a year. and forget adding a graphics card to that. a 480w logisys is more like 300w. as above corsair, seasonic, antec, xfx and the like are what you want for any kind of reliability and they don't lie about wattage, power and 80+ ratings.
