Hi there community, as the title says, will my Cooler Master GX650W be a reliable power supply for a R9 290 Vapor X? And how much OC headroom would I have if any?

I've been looking in forums but seem to notice people say "as long its reliable" or "it seems good enough". I mean, how do people know that? Is there a place where i can find out or it just pure knowledge of components?

PC Specs:
CPU: FX 8350 (Stock)
Motherboard: Gigabyte 990FX UD3 Rev. 4
HDD: 1TB Seagate 120MB Cache
PSU Cooler Master GX 650
GPU: Sapphire HD 7850 OC (Current)
