Can I fit a 600W PSU into a DX 4850?
Gateway DX 4850?http://www.pcmag.com/article2/0,2817,2383241,00.asp like that? Any atx form factor psu will fit, yes it takes the standard atx psu in that case, no matter the wattage, they are all going to fit
Just be sure to buy a reliable one of tier 1 or 2 ..............http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html
