looking a new psu

[cully4299]

need help looking a psu

replacing mu aerocool 700w bronze had it 3 years and is the oldest part in my pc as took it from my phenom x4 build.

looking to replace it this Christmas with something good,

looking around same wattage but gold or higher efficiency

looking to spend up to 120-150 deepening as it will be in the system for a few years.
looking something preferable with low fans that wont kick in till a certain stage like my GPU.

fully modular

my specs are in the signature below.

thanks in advance.

thanks guys. either going for the corsair or the super flower.

yea i know 550w would be sufficient but i plan to keep it for a while and maybe plan to do some expansion/use on next build so for the small price difference id like to just have a bigger one.
