Will my PSU be able to run two R9 270x Vapor X?

Here's my current build;

Intel Core i5 4690k
MSI z97 PC Mate
2x4Gb Kingston 1600Mhz RAM
Saphire R9 270x Vapor X 2Gb 256bit
1 Tb Seagate Barracuda 7200 RPM
Cooler Master Hyper 212 Evo HSF
PSU: Corsair CX600M


I'm planning to get another R9 270x vapor X and do crossfire with it. I don't really have the budget to get another PSU that would supply more power to run the whole system and I am not willing to upgrade my Graphics card to 280x or 290x. Do you think my current PSU would run a crossfire of R9 270x?

I wouldn't do it with a Corsair CX. It may be mathematically possible but the load on the CX would be quite high which would shorten the life of the PSU rapidly. The CX series also uses cheap capacitors that can pop.

To me, it's a bad decision.

Great! Thank you for your response. Somehow, it's good to know that it would shorten the lifespan of my PSU. I think I'd go ahead and do crossfire for now. I could just save money while it's still working fine and get a better PSU in the long run. What's important is it will work. About the capacitors popping, if that happens, it wouldn't affect any of my other components, will it?
