There are several motherboards that are not manufactured, rather they are bought from another manufacturer and have their tag sticked to them, as it happens to those from Amptron, Alton, Aristo and Matsonic. Matsonic used to sell their board under the brand "Eurone. All those "manufacturers" buy boards from ECS (EliteGroup Systems), which is one of the largest motherboard manufacturers in the world and is also the owner of the brand PCChips, one of the most popular motherboard manufacturer in developing countries because of their low prices.

ECS says they use the brand PCChips for their boards for the low-end PC market, while the boards sold under the brand ECS have better quality control. However, several ECS and PCChips motherboards are simply identical.

For example, if you buy an ECS K7SOM+ motherboard in the belief you are making a better deal than buying one from PCChips you are mistaken, for that motherboard is actually the M810DLU from PCChips. Similarly, if you an MS9138E from Matsonic you will be really taking home an M925 from PCChips.

We compiled two tables showing the correspondence of the most popular cloned motherboards on the market today. Notice that that table is far from being thorough, being just a fast guide to be used when buying a low cost motherboard.
