I just realized that I need a new power supply before I can buy the Nvidia Geforce 750 Ti this thing is the recommended wattage of about 300 Watts the power supply only has 350 W of power that's about like what 50 W of power left. The pictures here is begin look at it is all the power supply itself I am not sure if an aftermarket power supply wouldn't have enough clearance in the case not to mention all of them have switch on their. So I'll let you decide do you think I have enough space to put a new power supply in or not? I also know that I would need a modular power supply to stop all the wires from clogging up in the case and restricting airflow.
