PSU Wattage with r9 280x?
(Specs at bottom)I have a 450w Bronze TR2 Thermal take PSU for my custom built pc. I have a r7 260x right now in it, and I am looking to upgrade it to an r9 280x. From the little bit of research that i found it says you need atleast 650w of power to run the 280x, it says its tdp is 250w. I have enough space on my psu for the 250w. But i dont want to purchase the 280x if it is incapable of using it without a 650w PSU.
FX-6300 CPU
Thermaltake 450w Bronze Cert. PSU
R7-260x GPU
Asus M5A78L-M/USB3 Motherboard
Patriot Sig. 8gb RAM
1tb Western digital 7200 rpm hdd
I was just wondering if you needed the 650w to use it at all
I built it Late july 2015

things to consider:
1. overclocking eats more power than the reported specs
2. older psus are generally less capable of sustained high power output
I checked actual measured power consumption under gaming conditions via this article: http://www.tomshardware.com/reviews/radeon-r9-280x...
the r9 is significantly higher -- over 130 watts higher. offhand, i'd not put that into an older box unless there was at least 10% headroom over needs with the psu -- which I doubt you have.
