r9 270x crossfire psu dilemna

[poormansbuild]

Hi guys i have a bit of a problem. so i want to add an additional sapphire r9 270x toxic to my rig. 

 

One of the issues i have is that my power supply only has one 6-pin connector, and one 6+2-pin connector. and i will need 2 more 6 pins to accomodate my incoming r9 270x.

 

I was wondering if i should get a new power supply or is there like a way of still using my existing psu, like daisy chaining the r9 270x's? and also is my psu's wattage enough to support another r9 270x? 

 

My psu is a seasonic s12ii 620w 80+bronze

 

my current rig:

 

processor: i7 4770k

 

cooling: corsair h80i

 

graphics card: sapphire r9 270x toxic

 

ram: 16gb 1866 ripjaws gskill

 

ssd: corsair force ls 120gb

 

hdd: wd black 1tb

I would say get a 750w. The fact that your PSU doesn't even have the proper cables is a sign that it's probably not meant to handle that.

^ what he said. If it doesnt have the cables it sure as hell wont have the Amps on the rail to support both cards.
