I want to upgrade my graphics card to R9 I have intel i5 quad core 3.0 ghz 8 gb ram, can I run R9?
You can if your power supply is sufficient...I recommend at least a QUALITY 650 watt.
Yeah, it depends on the R9.
The 270x, 370 & 380 gpu adapters can also be run on a quality 500W PSU.
Amperage through the +12v power rail is the key though...
Agreed with kingfish and backfire, but I'd buy a Corsair, SeaSonic, or Enermax 750w 80 Plus Gold or Platinum unit so you won't have to worry about replacing it for well into the next decade.
