You will need at least 1100-1300 watts. Also, I would use a CM PSU.

Well, 850W is the minimum to go with R9 290 CF. But in your case, it's not recommended. Your PSU isn't of the best quality, nowhere near. Its tier 3 and must not be used for CF. Buy a better PSU.

@zeyuanfu, a high quality 850W or 1kW to be on the extremely safe side would be enough, and I'd NOT use CM PSUs for such high end builds.

Antec HCG/ SeaSonic S/M12II/X series/ XFX Pro series/ EVGA G1/G2 850W or higher models would be good for the purpose :)

No worries @zenyuanfu.

Yes 900W/ 1kW will always be a better buy (from the models/ series I suggested, not a Corsair or Thermaltake). That's why I included 'or higher' to be on the safe side :)

1kW EVGA SuperNova G2 ($170 on NewEgg) is the best value for money out there, as Blackbird said, 1kW will be on the safe side. And G2 is a great performer too :)
