Don't get that motherboard if you're going to make use of that 2500k - you cannot overclock with it. Get a Z77 motherboard - if you're looking for something affordable, something like an MSI Z77A-G43
, or ASRock Z77 Pro3
, or Biostar TZ77B
would be better than that H61.
The only Rosewill PSU I can recommend is the Hive series (which are good, at best). This Seasonic S12II 620
would be much, much better - more efficient, quiet, more reliable, better support, etc.
