Silverstone and Seasonic are both fantastic brands.
If this doesn't work out for you newegg had the Seasonic X750 for around $110 a couple weeks ago. It will hit that again eventually -- they do a lot of sales.
Silverstone is a quality product - I did quite a bit of reading before I bought mine- sure there are other very high quality manufacturers but a good price on SS will keep you happy for years.
