“Is it OK to upgrade a graphic card (gtx 750 ti) without upgrade a power supply? This graphic card's System Requirements is up to 150W. I think 180W power supply is not enough. should i upgrade power supply?”

• This system's power supply is 180 watts. It can not be upgraded because the motherboard and other components are matched to the 180 watt power supply.
