theres no real reason why it cant. your psu is a little weak but should just be enough...
try a more demanding game if you get the same results its either the tri core isnt up to the job which is unlikely as tri core is pretty much the minimum requirement for even dual threaded games 1s you take the o.s over head into consideration.
your gfx takes about 130w, cpu 95w, memory 10w per stick fans 5-10 w each. motherboard 5-25w hdd 20w each dvdrom 40w
tot em all up and thats your max power draw. if your close to 350-370 then you can assume your psu is starting to strain.
