The Asus P7H55-M motherboard under analysis here is a retail version of an ATX form PC motherboard featuring an Intel H55 chipset solution [without CPU or memory modules].
For the purposes of this analysis, product lifetime volume is presumed to be 1M units.
As a reminder, volume production assumptions are meant primarily to be used for our cost analysis in terms of amortized NRE and tooling costs, especially for custom components specific to the model being analyzed (mechanical components especially), and not necessarily as a market accurate estimate for a specific model. Our estimations are based on iSuppli market research and we derive rational estimates based on overall market shares of the manufacturer in question, as well as the number of products in a given portfolio and the relative popularity of certain lines of products.

What Is Not Included in our Cost Analysis
The total materials and manufacturing costs reported in this analysis reflect ONLY the direct materials cost (from component vendors and assorted EMS providers), AND manufacturing with basic test. Not included in this analysis are costs above and beyond the material manufacture of the core device itself - cost of intellectual property, royalties and licensing fees (those not already included into the per component price), software, software loading and test, shipping, logistics marketing and other channel costs including not only EMS provider and the OEM's margin, but that of other resellers. Our cost analysis is meant to focus on those costs incurred in the manufacture of the core device and exceptionally in some circumstances the packaging and literature as well.
Country of Origin / Volume Assumptions
The Asus P7H55-M motherboard is assumed to be produced in China.
Country of origin assumptions relate directly to the associated cost of manufacturing, where calculated by iSuppli. In the cases of 'finished' sub-assemblies (such as chargers), we do not calculate internal manufacturing costs, but rather assess the market price of the finished product in which case country of origin assumptions may or may not have a direct effect on pricing.
Design for Manufacturing / Device Complexity
The total component counts of the Asus P7H55-M motherboard are as follows:
- Motherboard 1047
- Box Contents 14
Component counts have a direct bearing on the overall manufacturing cycle times and costs, and also can increase or decrease overall yields and re-work. Our calculations of manufacturing costs factor counts and more qualitative complexities in the design
Note that manual labor has a much smaller effect on auto-insertion assembly lines (for the Main PCB, for example), where manufacturing costs are much more capital equipment intensive and driven by these investment costs.
