I'm going to get a new graphical card that uses 20 watts more than my old card.
Am I supposed to get a new power supply now?

This is a medion PC and there is no way to get specs on certain parts so I don't know how many watts my current power supply outputs. However I'm wondering if I should get a new PSU for 20 watts difference. It's said that the Club3D Radeon HD 7790 '13Series requires 450 Watts to function though. Does that mean 450 Watt has to be free at all times?

Thanks. It's 400 Watt. So 50 short. If I get a 500 watt PSU would that be ok?
