Okay, I'll go with a decent 650w PSU then. But will a r7870 Hawk do it's job while gaming or video-editing? I don't need massive, but just reasonable. Cause if that Graphics card is just reasonable I won't ever buy a second one for Crossfire, which will give me some more security for my PSU choice.
