  1. I will recommend a 600-650 watt power supply. NEVER skimp on your power supply. If it breaks, it will break other components, mainly CPU, motherboard, and GPU. I recommend a Corsair CX 600 or a TX series if you can afford it.
  2. Best answer
    Yeah, we should not be a 'miser' in case of PSU. A faulty PSU can take all of your hardware to 'black burn of death'. I think a 550 watt from XFX would be a great option. XFX are the finest PSU makers across the globe.
  3. A quality 450w(seasonic, XFX) will power it just fine...7750's an extremely low powered card.
