Recently, Epox has been gaining some significant traction in the enthusiast motherboard market, dominated by overclockers and bleeding edge performance and features gurus. It's no wonder that AnandTech's very own forums are filled with Epox-related news, reviews, and all types of information related to Epox mainboards.

Quite frankly, we have to agree, Epox is doing a lot of things right. They clearly have the fastest Socket A KT333 motherboard on the market (only by a small margin though), dubbed the 8K5A2+. In fact, the Epox 8K5A2+ is faster than a number of KT400 motherboards available today. Overclocking-wise, it doesn't seem like many boards can match what Epox is able to consistently dish up. After talking with several Epox reps, we learned that Epox's "secret" to engineering consistently well-overclocking motherboards is to design boards with cleaner circuit layouts, which help in feeding a steady voltage to all the components on a motherboard.

There are many factors that are helping to make Epox as famous as they are. We examine some of those factors by taking an in depth look at Epox's latest Socket 478 motherboard, the Epox 4PEA+. Read on to see what you're missing…
