Can I connect my Power Supply to my R9 280x using a EPS-12V 8pin to 2 x PCI-E 8(6+2)pin connector?

The power supply:

I nabbed the PSU out of another computer I'm not using so it doesn't have all of the cables it normally comes with. I could use the 2 8-pin to molex cables that came with the card, but that's 4 molex cables that I don't have and I'd rather use a single cable if possible.

I am aware the Vapor-X card calls for a 750W PSU, but I'm not going to overclock or crossfire them and I've read that it can manage that way. If any more info is needed or if there is a better solution to my problem (or if the PSU simply won't cut it), just let me know. Thanks in advance!

EDIT: Read somewhere that the R9 280X requires 30A on the 12V rail. So I may need to nab a different PSU anyway. I'm still curious about my previous question though
 
Solution
In theory, the connection itself should do the work, but I am having doubts the PSU has the juice to power is because from what I could find it's double rail and below wattage specs. Now if we were talking about a 700w+ single rail PSU, I would say YES, but in this case it's a bit hit and miss. If you cant get another PSU, your best bet is to try it out and see what happens. From what I know, worst case you'll get an insufficient power warning or computer shutdowns when your system will be under high load. It's a gamble.

It is a double rail

Better to get a new PSU than to order cables for this one if it can't handle it anyway

Yes, if you can afford it, that is the best thing to do. The PSU is the heart of your computer, you do not want to be cheap on that. A cheap PSU will burn and take with it a GPU or MB worh hundreds of dollars.
