Jacked-Up: EVGA GeForce GTX 780 SC with ACX Cooling

3 thumbs up

The EVGA GeForce GTX 780 SuperClocked with ACX cooling’s main differentiator is obviously its custom heatsink and fan assembly.

The dual-fan Active Cooling Extreme, or ACX, cooler features a large heatsink array, with 40% additional fin volume over reference designs. If you look close, you’ll notice that there are actually two heatsinks, one that sits right atop the GPU and another just to the right, and that the heatsinks are linked to the baseplate by multiple thick heatpipes. There is an additional heatplate mounted to the PCB as well, which adds strength and helps keep the PCB flat.

The fans used on the ACX cooler also got some special treatment. According to EVGA the fan blade design offers superior strength than standard fans and the dual-ball bearings offer increased longevity over more common sleeve bearings.

All told, EVGA claims the ACX cooler outperforms reference coolers, while reducing weight and thickness, and it should be quieter and last longer too. With the GTX 780 and its GPU Boost 2.0 feature, however, the card will ramp up to whatever target temperature is specified in the driver, by dynamically boosting and adjusting the GPU frequency and voltage as necessary based on the workload. That means the ACX cooler may not necessarily always offer lower temperatures than a reference cooler, but it should allow the card to remain at max boost for longer periods, which should ultimately increase overall performance.

As for the card itself, we think she’s a real looker. The EVGA GeForce GTX 780 SuperClocked with ACX cooling is a dual-slot card, but it is slightly thinner than the reference model. As the “SuperClocked” in the name suggests, this card is factory overclocked as well. Whereas reference GeForce GTX 780 cards sport 863MHz / 900 MHz GPU base and boost clocks, respectively, the EVGA GeForce GTX 780 SuperClocked with ACX cooling come in at 941 MHz (base) / 993 MHz (boost). All of the other specifications, including the 3GB of GDDR5 memory clocked at an effective 6008 MHz, remains unchanged from the reference model.

As evidenced by the pair of SLI edge connectors at the top of the card, the EVGA GeForce GTX 780 SC with ACX supports up to 3-Way SLI, and because the TDP of the card is only 250 watts, single 8-pin and 6-pin supplemental PCI Express power feeds are all that are required to power it.

 

Outputs consist of a pair of dual-link DVI outputs, a full-sized DisplayPort output, and an HDMI connector. The EVGA GeForce GTX 780 SC with ACX has more than enough muscle to push multiple displays simultaneously, and as such, it supports NVIDIA's 3D Vision Surround technology, as well other proprietary NVIDA technologies like 3DVision, PhyX, and the like.

In EVGA we trust!

Honestly though it's getting kind of ridiculous how expensive pc gaming is getting. I wish there was a bigger drive for some kind of software revamp that will allow games to run better with lower end hardware.

Ps. "Quite Cooling" , I think you meant quiet ;)

To be honest, I don't see how the landscape has really changed in this regard. There's always been expensive GPUs for those who want them, and lesser-expensive ones alike. I'd actually say things are way better today than 5 - 8 years ago. Years ago, I always felt inclined to buy $500+ GPUs, but today, $200 - $250 offerings are -so- powerful, they're totally suitable for most gamers. Those running higher than 1080p resolutions, multi-monitor or desire the highest possible detail settings are the ones who will need to shell out more.

"Although its GK110 GPU has fewer active CUDA cores and texture units than a GeForce GTX Titan, the EVGA GeForce GTX 780 SC with ACX cooling's higher clocks allowed it to overtake the Titan's performance more often than not."

Enough said. Damn! Great review, Marco.

I was happily running a gtx590 Classified from Evga for two years, but since I upgraded my monitor to 2560x1440 the old dog is struggling really bad. Playing a bunch of combat flight sims that eat up a lot of video memory is not helping either.

While at 1080p most console ported games run ok on cheaper cards, I think most modern games, made for PC, will need a more powerful card this days.

You are correct, sir! :) Fixed. Thanks for the head's up.

Great review, just ordered on Newegg after cancelling on Amazon for a different card, this is clearly the one to get. Also thanks for the power info, I'm running a 650 and was wondering if I would be a problem and knowing the adapters are included is a plus as well. I game, but I also work as a video editor, I can actually do renders at home with this thing, that many cuda cores allows Adobe CS to render 3D and HD at near pro system levels, amazing for the price. Currently I have a GTX 660 at home and was amazed at the performance for a $200 card, Metro Last night looked great on it, interested to see the difference with the 780 for myself.

I'm glad I read this benchmark. I am super excited for when I get my 780's... if I ever have the funds for such a thing. But I'm even more excited for the sweeps that just went up including a 7990 in the build. I guess you have to take AMD seriously too. Awesome review. It's also good to know that my 1200i won't be needing a replacement till it dies.

very informative review, I will be using this to help decide my next purchase

Wow, that is a beautiful card! I don't know if it is worth me spending that amount of money though, unless I had extra money laying around! $659 is allot to spend on a card, especially since I spend half that on two MSI Twin Frozr Hawk Edition 6870's! They have great performance for half the price and am very happy with the temps I am getting from them! I am running Mac OS X 10.8.4 and Windows 8 with them. I can play games on both Operating Systems!

I can't wait for my paycheck, this particular graphics card seems like the perfect card for my ultimate gaming pc that I will be going to make! :)
