Hello, I wanted to know is it worth to pay 4 more euros for 650W PSU even if 550W is enough for me, is it better that I have less % load on my PSU and is there any differenece between these two PSU's, It looks like 650W one has 4x6pin but official page says only 6pin but newegg says 6+2pin connectors, so I'm not sure.
