Power Supply Wattage

[akruet227]

I currently have a 600 watt Corsair supply with an AMD FX 8320 and a Gigabyte GeForce GTX 760 with an 8-pin and 6-pin PCI-e connectors. I know that I need to get a new power supply, but if I wanted to get another Gigabyte GTX 760, should I get a Corsair 760 watt power supply, or add 100 more watts and get an 860 watt power supply?

850 watt would be ideal for 760sli as it would give you some headroom for future upgrade.
Go for corsair,seasonic or xfx.

Mo Powa never hurts. Not sure but I think 700 might be the minimum for 760's in SLI 760W is cutting it close
