We asked around and we learned that SuPox is not Epox, but it is made up from ex Epox people. Since Epox went down, as we wrote here, a big number of ex Epox staff decided to make a new brand and a new company and simply call it SuPox.
As it is not easy to start a motherboard company, these guys wants to stick to an existing motherboard design. At this time the company is making some low end boards including Nforce 520LE, Nforce 570, AMD 690G as well as a bunch of Intel boards based on the 945G, 945P and 965G chipsets. The company started in April 2007 and hopes to stay in business.
