Chaintech 9EJS1 ZENITH 845PE: zenith: n. - the highest point; peak; acme: the zenith of someone's achievements. Will the Chaintech 9EJS1 ZENITH be just that? We'll be investigating that today.
Date: February 7, 2003
Written By:

Long time manufacturers of motherboards and video cards, Chaintech has been gaining momentum in mindshare among enthusiasts. Their current GeForce 4 product line breaks away from nVidia's reference design by adding ramsinks and a slightly modified GPU cooler. By thinking about the enthusiasts, they have turned their sights at motherboards and have released a product line dubbed the "Zenith" series. These motherboards are to pack in as many features as possible, while at the same time attempt to be one of the top performers in its class. Today, we'll be looking at their Pentium 4 i845PE motherboard, the Chaintech 9EJS1 ZENITH.

Whew! Quite a list. As stated earlier, this is an i845PE based motherboard, with the Intel ICH4. What that means is features such as Hyper-Threading, USB2.0, ATA100, DDR333 and AGP4x are supported natively. The 9EJS1 ZENITH also features RAID, onboard LAN, and 6 channel audio.

The ZENITH is packed into a nice black box, complete with carry handle. The "Z" cutout extends to the inner box, showing off the hardware on the shelf. The handle is fairly useless if your motherboard is inside your PC, but I suppose you can always pack your lunch in there and impress the chicks at the lunch table by hauling it into the cafeteria. Inside, you'll find the motherboard (in it's own plastic shell), as well as the rest of the accessories neatly stowed.
