It has been a long while since we last looked at an EPoX motherboard and we thought it's about time we review a product from one of the most well-known manufacturer for its overclocking prowess. EPoX has been in the industry for quite a while and they have built quite a reputation for themselves with boards that featured some of the best overclocking tweaks - with some even rivaling ABIT. While it's a board built for the enthusiasts, EPoX boards also appeal to the mass consumers simply because its features were adequate and are often priced attractively.

The EP-4PCA3+ is the Intel 875P offering from the folks at EPoX and it comes with its own set of unique features targeted at the power user. Probably the most fascinating aspect of the board is in its vast Ultra ATA-133 support which proudly boast to be the industry's only 875P board with IDE RAID 5.

The EPoX EP-4PCA3+ comes with the usual 1 AGP and 5 PCI configuration with built-in audio and Gigabit LAN support. We'll look into those features in detail in the next page but before we do that, let's look at the technical specifications in the table below.

The EP-4PCA3+ comes with 5 PCI slots and 1 AGP 8X slot.
