Need more power for above. Conflicting information for graphics card. Microcenter website states only 200 watts needed/ box states 400 watts. Current power supply 300 watts. I can run games/ Bioshock Infinite- Metro Last Light Redux with no problems. Will upgrade CPU eventually. What power supply would give me the upgrade ability in the future and not fry my system now.

thanks for the quick response. Being new at replacing PSU the current PSU has the fan on the back of the unit where the central power come in. These have the fan on top of the unit. No airflow at top of case. the upgrade of Ram and graphics card gives a benchmark on Passmark of 2957.

I apologize for the newbie questions. If I mount it with fan facing up, this puts it directly under the case with no airflow. If I mount it facing down then it is directly over the fan from the graphics card. Heat is not an issue when running anything, but with any prebuilt, more fans blowing inside the case, more heat build up. Got the unit dirt cheap so I knew I would need to upgrade some items. Thanks for your patience.
