Recipe for disaster.  150W / cards. Don't dual power on same cable.

Each GPU raiser can feed up to 50W single GPU load.

Power = Voltage * Amps. 

More amps in cable, more copper needed.

Also pulling 1KW + 24hrs /7 load on domestic socket can be hazardous if you have no clue of what you're doing.
Ask more questions, read more, learn more. You need basic 101 electrical knowledge to be successful.

Good luck and don't burn down your house.
