EVGA has announced a cosmetic upgrade for users of multiple Nvidia graphics boards: the EVGA Pro SLI Bridges, due to launch in the very near future.

For those who have only ever run single-board systems, an explanation: Scan-Line Interleave, introduced to gamers with the 3dfx Voodoo2 accelerator board, allows multiple graphics cards to be chained together with each rendering a portion of the screen. Back when graphics cards ran at 90MHz, they were connected with a cheap ribbon cable - but given the gigahertz-plus frequencies of modern GPUs, these days it's more common to see a printed circuit board known as a bridge used between the cards instead.

EVGA is one of a number of companies who produce graphics cards that can be chained using SLI bridges, and has now decided to offer something for those who want to prettify their rig: Pro SLI Bridges.

The company's SLI bridges don't offer anything extra in the way of performance, it must be pointed out, but are designed to bring a bit of glamour to the inside of a PC's case - something likely only appreciated by those whose cases feature a side-panel window. To launch in two-way, three-way, and four-way configurations, the EVGA Pro SLI Bridges include brushed aluminium panels on the curved top surface.

At the centre of each bridge is the EVGA logo, and while the company has included some LEDs to illuminate the branding they require something of an investment in graphics hardware: the LEDs will only light when the bridges are used on Nvidia GeForce GTX 700-series or later graphics boards, including the GeForce GTX Titan.

While you'd be forgiven for thinking that the presence of the EVGA branding makes the bridges an exclusive for the company's boards, EVGA has confirmed that they are compatible with all SLI-enabled graphics cards. For those whose graphics boards aren't new enough to illuminate the LEDs, the branding will be barely noticeable.

EVGA has provided some teaser images on its website, but has so far been reticent to provide a launch date or pricing for the Pro SLI Bridges.
