Power req for 1070 sli?

[Jonadong]

I have a 500w psu. Would that be enough to sli two 1070s (I already have one), and power a i5 6600k

No.

 

Most 1070s recommend a 600W for a PC with one. For 2 I'd get a 750W minimum.

For two graphics cards if they require dedicated power I wouldn't recommend running them off a 500W. Idle at the desktop you'd probably be fine but as soon as you put them under load there'd be a voltage draw spike. It'd exceed the PSU output rating and the system would shutdown.

750watt would be a good idea, to be on the safe side.

http://www.coolermaster.com/power-supply-calculator/ put all your components into this and then it will tell you the wattage you need

Get the biggest watt PSU you can afford to get and remember give yourself some headroom. Your PC parts also require power as well. DONT borderline it or you will regret it.

I would go with at least a gold plus or higher as you want to protect it, and fully modular for a cleaner look, and better airflow. Also if you wanted too you could used colored cables for a sweet looking design.
