Cooler master, at least to my understanding is a pretty reliable on psu's. Either one will be fine. Just something for future reference, when purchasing a psu, always look at the specs and see if the rating is continuous(output will always be what it's rated for) or maximum (what the psu can reach randomly for all intensive purposes) with it's continuous usually alot lower than this
thanx 4 all the responses. i also thought a 250W psu wasn't gonna cut it. as for the recomendations, i live in Canada, but ive already found a cheap 600W psu that i'll use with a gts 250 (my budget increased after my birthday).
