What is the difference between bronze power supply certificate and gold power supply certificate

Solution
XFX TS Series 550W P1-550S-GREN and P1-550S-XXB9 are 80 PLUS BRONZE efficiency certified.

XFX TS Series 550W P1-550G-TS3X is 80 PLUS GOLD efficiency certified.

You have to look at the specific model number and make sure you are getting that specific model.

System Power Supply Requirements for a single AMD Reference Design Radeon R9 280X
AMD specifies a minimum of a 600 Watt or greater system power supply. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)
the system power supply must also have a maximum combined +12 Volt continuous...

heyhey Dan :D
I'm not at all a expert. (Hope someone with hands on exp jump in)
But from what I've seen what components are used inside the psu are significantly more important then the cert'

Example: http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html
I just happen to own the only Bronze in the top tier.
A XfX xxx ed' 650 modular.

Also I noticed on that list. The Ts is gold and bronze...
Take this with extreme grain of salt. But Maybe they pushed the product out the door before geting gold cert? in which case there is no diffrence except one has a gold sticker and one doesnt.
Thast pure speculation!!
Either way thats a very good quality psu. you wont be disappointed.

AMD specifies a minimum of a 600 Watt or greater system power supply. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)
the system power supply must also have a maximum combined +12 Volt continuous current rating of 37 Amps or greater
the system power supply should also have at least one 75-Watt 6-pin and one 150-Watt 8-pin PCI Express supplementary power connectors. There are some non-reference design cards that require two 150-Watt 8-pin PCI Express supplementary power connectors because they may draw more power.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

What is the specific brand and model of your Radeon R9 280X card?
