Dragos Manea :
Any standard psu will be compatible with any motherboard. The seasonic will work and it is a very high quality psu.
Indeed the both are very nice but the full modular is always nice to have as well! As PSU`s go, like he said, Seasonic are very high quality and you can not go wrong. Won`t trade my (granted a bit OP) X-Series Seasonic for anything. Bought that thing 4 years ago and still have another 3 years warranty on that bad boy.
