what are the systems spec? for any 280w psu, its usually crap or a sign that you need a completely new rig
yes iknow it's crap but it's all i could get in a hurry when my pressario went pop, amd 64,3 gb ram (soon to be 4) just a stndard dell dimension c521(as you can tell i know little about these things) thanks
as basic build starts around 500, 700 gets you hardware that can play high or a bit better settings, 850 gets you ultra settings for the most part and 1000 will get you SSDs and max out most games.
higher end builds after 1000 has the option for overclocking and dual card configuration options
