EVGA GeForce GTX 770 SC with ACX Cooling Review
Introduction and Specifications
Coincident with the launch of NVIDIA’s GeForce GTX 700 series of products, EVGA unveiled a new invention of its own: the ACX cooler. ACX is an acronym for "Active Cooling Extreme" and as the name suggests, it’s a cooling solution for high-end graphics cards. To date, we have looked at two ACX-equipped graphics cards, the EVGA GeForce GTX 780 SC ACX and GeForce GTX 760 SC ACX. We found both cards to be class-leading products and liked them very much. And so far, the EVGA GeForce GTX 780 SC ACX remains the fastest, single-GPU powered graphics card we have tested. It’s factory overclock allowed it to overtake a standard GeForce GTX Titan.
Today we’re going to take a look at yet another ACX-equipped graphics card, the EVGA GeForce GTX 770 SC ACX. As you probably know by now, the GeForce GTX 770 falls in between the GTX 780 and GTX 760 in NVIDIA’s current product stack. It is a more refined update to last years’ GeForce GTX 680, but with a few new features added and somewhat higher performance. The EVGA GeForce GTX 770 SC ACX takes the GTX 770 up another couple of notches thanks to its more powerful cooler and higher factory clocks. The card’s full specifications and accessory bundle are below and we’ve got a full performance profile on the pages ahead...

We’ll dive in and take a close look at the EVGA GeForce GTX 770 SC with ACX cooling in just a bit. But before we do, we want to show you some of the goodies EVGA bundles with the card.

Included with the EVGA GeForce GTX 770 SC with ACX cooling, we found a rather cool “Game of Pwns” poster, some large “Enthusiast Built” decals, various documentation, a driver / utility CD, and a few adapters—a dual-6-pin to single 8-pin PCIe adapter, a dual-peripheral to 6-pin PCIe adapter, and a VGA-to-DVI adapter. Unfortunately, there were no games to speak off, but EVGA does include all of the essentials. And we should point out that the company gives away its excellent Precision X performance tuning tool for free.
