Will my Cougar SL500w PSU be able to run an MSI R9 280X?

I'm planning on upgrading my graphics card to an MSI R9 280X Gaming OC but I'm worried about my power supply, as I don't think I'm gonna be able to upgrade it right away alongside my graphics card. It has a 6-pin and a 6+2-pin connector but will the wattage be enough to power it?

Probably, yes. But it is not recommended. The R9-280X normally requires a system with a 600W PSU: http://www.realhardtechx.com/index_archivos/Page362.htm

That site might be a bit off in their power wattage requirements - 650W for a standard R9-290X? It requires a competent power supply, not just one with a ridiculously high wattage. PC Part Picker estimates that for an Intel i5 and a R9-280X is about 380W. A solid 550W should do the trick. Power requirements are usually grossly overestimated by graphics card manufacturers because they automatically assume that poor quality power supplies are going to be used. A Seasonic, Super Flower, or one of the new Andyson units should handle the trick at 550W minimum.

Good point. That's why I included a disclaimer. Like you, I didn't know the make/model of the OP's PSU.
