Ok, so I can ether buy the Sapphire or the Asus model of the Amd R9 290 for the same price (second hand for about €250,-) and I wonder which card is the best (tempature and low noise especially are important to me). Thanks
For a pc running a R9 290 you need a good power supply of 650W min. Try XFX 650 or Seasonic 620 or Antec HCG 620M.
Advice around getting a 750W psu would be based on getting a crappy one. I only recommend good ones.
So I' m thinking about getting ether the corsair tx650 or the cx750. Will the 650W from corsair do the job without taking a risk? (also thanks for the quick reply)
