I'm looking to build a mini-itx system and for the most part have selected all the components already. Since I plan on using a picoPSU, 150w is about as high I can possibly go. I read this article from the site: http://www.silentpcreview.com/article959-page8.html
My first impression would have been, that'll never run using only a 65w adapter. The C2D E7200 is a 65w CPU and then coupled with the other components I don't see how it could run without issues. However, they said it ran find. In my setup, I'm looking at using either an i5 or i7 (depends on budget at the time), using only 65w TDP models. Technically speaking, my system should be around the same power requirements as their test configuration.
My planned configuration:
ASRock H67M-ITX/HT motherboard
Intel i7-2600S, i5-2500S, i5-2405S (still debating)
Samsung 2x4GB DDR3 1333 (VLP)
Crucial 64GB SSD Sata3
WD Green 1TB 64mb 5400rpm Sata2
If that can actually run with only 65w, then using a 150w PSU might give me room for a small dedicated graphics card later on if I feel the HD2000/3000 doesn't cut it. But what do you guys think?
Side note: I looked at getting a Nexus Psile case (would have to ditch 1 hdd though), but the lack of available is making it difficult to consider. I'm currently rendering a model of my own design.
