Power Supply Wattage recommendation

[Glockinator19]

I was wanting some recommendations on a new power supply wattage to power my recent build I finished a few months back, upgrading to a full tower and want a modular PSU for a better look. Here's my specs:

ASUS Z97 Sabertooth mark I
Intel I7 4790k @4.0ghz
2 MSI HD R7950 crossfire
2x8gb ddr3 patriot RAM
Crucial M4 128gb SSD
1TB Hitachi HDD
DVD/CD drive
Razer blackwidow ultimate keyboard
Razer deathadder mouse
5.25in card reader/USB ext
4 200mm LED thermaltake fans
1 140mm thermaltake fan

Probably more info than needed but it can't hurt! I tried a calculator or two but want feedback from real people with experience and opinions! I was thinking something like the CORSAIR RM750

I would stick with Evga as far as the brand goes, they seem to make good psus and their customer service is good if it ever goes bad on you. And I would go 1000w+ gold. That will give you more then you need at the moment and allow more wiggle room for future upgrades.

The EVGA 850 G2 will give you plenty of power for both GPU's and overclocking. The quality and reliability of the G2 is top notch.

System Power Supply Requirements for two Radeon HD 7950 graphics cards in 2-way CrossFire mode
• AMD specifies a minimum of a 700 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 45 Amps or greater
• the system power supply should also have at least four 75-Watt 6-pin PCI Express supplementary power connectors.

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.

EVGA SuperNOVA 650 G2 (220-G2-0650-Y1)

• Ambient Temperature Maximum (i.e. without derating): 50°C
• Full /Semi-Modular Output Cables: Yes
• Passes Official Intel Haswell Compliance Test: Yes
• 80 PLUS GOLD Efficiency Certification
