Am looking at buying a graphics card. AMD or NVIDIA i don't really mind.
But i saw this PowerColor Radeon R9 390X PCS+ 8GB GDDR5 needs a 750w min psu. That can't be right can it?

A graphics card specific minimum requirement for something that's as much influenced by the rest of the system is always going to be a very vague figure. They tend to err on the high side compared to what the typical system needs.
390X power consumption on some cards can go as high as 400W so a 750W PSU suggestion for a similarly high end and overclocked processor isn't too unreasonable.
Thinking about it i suppose they are going by AMD cpu systems, which require more power. Well they used to any way.
Mine is a Intel 4790k system with a mild OC.
No, it's not at all right, the TDP for the 390X is 275W, your CPU's TDP is 88W, most other components don't add much in the way of power overhead even 60-70W is being really conservative for an average machine. So your 650W PSU will easily handle it. Your PSU wont provide connectors for anything it can't power, so if it has the connectors, it can power it unless you do something silly.
Typically these GPU PSU recommendations assume you're going to slap it in with the cheapest nastiest PSU that came with the tackiest case, overclocking the balls out of your CPU, and have 16 3.5" 15,000rpm SCSI hard drives running full belt. They're overly conservative to the point of absurdity, they're just covering their asses really.
Thanks for that.
