Hi there

I want to build a HTPC with the following specs:

MB: GA-H61N-USB3 (ITX).
http://www.gigabyte.com/products/product-page.aspx?pid=3963#ov

CPU: Intel Core i3-3220 3.30GHz (Ivybridge) Socket LGA1155 Processor (77W)
http://ark.intel.com/products/65693/Intel-Core-i3-3220-Processor-(3M-Cache-3_30-GHz)

RAM: 2 X Crucial 2GB (1x2GB) DDR3 PC3-10600C9 1333MHz 240-Pin Module (CT25664BA1339)
http://www.crucial.com/store/partspecs.aspx?IMODULE=CT25664BD1339

SSD: Kingston 120GB SSDNow V+200 SSD
http://www.kingston.com/us/ssd/vplus#svp200s3

My question is this, I want to use a ultra small ITX Case that comes with a 180 Watt PSU.
Will that be enough Wattage to run the ITX with the above build or will I be falling short?

The MB states that it needs 200 Watt but that's with add-ons etc, the processor is using 77 Watt.
I have a similar build at home with a 200 Watt power supply which runs fine, ITX board also states a minimum of 200 Watt

If anyone has some pointers that would be much appreciated.

Many thanks
Bellicus
