Looking for an opinion

Solution
the rm 850W from corsair is a real good psu
Delivered full power at 46°C
Ultra-quiet operation even when the fan is spinning
Semi-passive operation (leading to zero noise output at lower loads)
Fairly good voltage regulation
Good ripple suppression (although there is still room for improvement at 5V)
Fully modular
Six PCIe connectors and two EPS ones available at the same time
Numerous SATA and Peripheral connectors
Flat modular cables that are stealth
5 year warranty
Compatible with the Corsair Link system
Corsair Link produces very accurate +12V current output readings
Nice looks and finish
did some change..

The first 5 of the psu's you listed are all bronze rating efficiency, isn't it better to go with a gold rated one? And the last 2 you listed weren't in stock or wasn't available in my country
