A 60GB SSD really should go into most new builds now at least for an OS drive (and you can easily squeeze a game on too in most cases, OK I cant but meh I have a 2nd SSD anyway ).

But i'd agree with Dhalmel, http://www.overclock.net/ is a great place to read up, i also like Overclockers.co.uk, I would def have an OS SSD over a gaming one anyway.

With a PSU, again I'm just agreeing mostly, named brand over a cheap alternative will save you in the long run and less likely to fail on you at some point.
Work out what you need +10/15% then get a psu above that amount an your good.
Though I would say consider if you will keep it your for next Pc an Will you expand your GPU to multi card at some point.
If Yes then it might be worth pushing up the power a little, a m8 recently ended up with a the Corsair AX850, for the same price as the ugg... one of the 600 variants lol... he only needed similar to you but the PSU is 100x better with the modular cabling as well.
