Would a cheap (and i can't stress the cheap part enough) 500w psu be able to support a ATI 4650 graphics card?
Sure, but if you buy a cheap PSU that doesn't have a recognised brandname then you might as well flip a coin as to whether your computer will survive. Cheap PSUs tend to have an unreasonably high chance of dying, sometimes taking components with them.
dont ever do cheap PSUs, its like playing russian roulette, as suis said. Always buy a reputable brand such as antec, corsair, silverstone, seasonic, coolermaster or thermaltake. Also it depends on your other components, as it has to supply power to them also. Buying a cheap PSU could result in you having to replace your entire computer.
yeah i now know that. the psu came with the case and i didn't know cheap psus were so bad at the time. but now i have no money (not yet) i'll probably get that card and a new psu. know any good brands? the brand i have now is "power supply" ..... :/
wow i completely missed that.....thanks one more question. can i mount this to the top of the case? http://www.newegg.com/Product/Product.aspx?Item=N82E16817371044 it doesn't look like the fan will pull in any air if i put it on the top.
