I'm thinking of adding another GTX 980 into my PC but I'm wondering if I will need to replace my PSU. I currently have a Corsair RM 850W Gold Modular PSU and my current specs are:

i7 4790k 4.0Ghz
GTX 980 4GB
16GB RAM
2x SSDs & 1x 7200rpm HDD
NXT Sentry 2 fan controller with 6 fans

Would my current 850W PSU be okay or should I upgrade to a 1000W or 120mm?

System Power Supply Requirements for two NVIDIA Reference Design GeForce GTX 980 graphics cards in 2-way SLI mode
• NVIDIA specifies a minimum of a 750 Watt or greater system power supply. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)
• the system power supply must also have a maximum combined +12 Volt continuous current rating of 60 Amps or greater
• the system power supply should also have at least four 75-Watt 6-pin PCI Express supplementary power connectors. There are some non-reference design cards that...

System Power Supply Requirements for two NVIDIA Reference Design GeForce GTX 980 graphics cards in 2-way SLI mode
• NVIDIA specifies a minimum of a 750 Watt or greater system power supply. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)
• the system power supply must also have a maximum combined +12 Volt continuous current rating of 60 Amps or greater
• the system power supply should also have at least four 75-Watt 6-pin PCI Express supplementary power connectors. There are some non-reference design cards that require one 75-Watt 6-pin and one 150-Watt 8-pin PCI Express supplementary power connectors or two 150-Watt 8-pin PCI Express supplementary power connectors per card.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

Corsair RM850 (CP-9020056)
• OEM: Chicony Power Technology (75-001938) now discontinued or CWT (RPS0020) (Channel Well Technology)
• maximum combined +12 Volt continuous current rating: 70.8 Amps <===== More than Sufficient
• six 150-Watt (6+2)-pin PCI Express supplementary power connectors <===== More than Sufficient
• Full Modular Output Cables: Yes
• Official Intel Haswell Compliance: Yes
• 80 PLUS GOLD Efficiency Certification
