EVGA GeForce GTX 770 SC with ACX Cooling Review

Article Index:   

The EVGA GeForce GTX 770 SuperClocked with ACX cooling’s main differentiator is 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 underneath the shroud, one that sits right atop the GPU and another just to the side, 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 to 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 also reducing weight and thickness, and it should be quieter and last longer too. With the GTX 770 and its GPU Boost 2.0 feature, however, the card will try to 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 it looks great. The EVGA GeForce GTX 770 SuperClocked with ACX cooling is a dual-slot card, but it is slightly thinner than reference models. As the “SuperClocked” in the name suggests, this card is factory overclocked as well. Whereas reference GeForce GTX 770 cards sport 1046MHz / 1085MHz GPU base and boost clocks, respectively, the EVGA GeForce GTX 770 SuperClocked with ACX cooling come in at 1111MHz (base) / 1163MHz (boost). All of the other specifications, including the 2GB of GDDR5 memory clocked at an effective 7010MHz, remain unchanged from the reference model.

As evidenced by the pair of SLI edge connectors at the top of the card, the EVGA GeForce GTX 770 SC with ACX supports up to 3-Way SLI, and because the TDP of the card is “only” 230 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 770 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.

Goodness it'd be nice to have $400 in the budget for a graphics card. Someday...Someday...

I've been saving up money for a new video card for a while now... I have $50 left to save up to get this card. I had already picked it out as my target before this article came out. It shouldn't be too long before it'll be mine!

(Replacing a GTX 285 which gets flakey and locks up my computer from time to time)

Good luck with the 770. As far as the 285 goes you prob need to turn the fan on to 100%. Buddy of mine has an EVGA 285 and it kept overheating on him playing games like BF3 then figured out it was just a heat issue. When it hits over 80C it just would died a horrible death but figured out if he cranked the fan to 100% and drowned out the noise he was good heh

can't afford for those GPU

It has a good warranty and the performance is pretty good too.

Love to have a pair of them for a little SLI goodness,...........Smile

Would be a good upgrade if i had the money!

My friend just got a pair of those for a build and he loves them. Running a number of games at above 80 fps and crisis 3 at around 60 with dips down to 50 on max settings.

This might just be my next card in about 3 months...got to get some cash saved up some how!

The 700 series is good but now im curious what the AMD 9000 series is gonna be like. Finally caught up on stuff from the past month or so and saw the 9000 series might be released in October I think it said.

Hasn't it been just like this for years of PC gaming? There is always something newer, better around the corner to whet our appitites for performance.

It's an evil plot to get all of our disposable income. (something I have less and less of as time goes by)

Lol Neil, you would be correct except its the whole PC market :P

I just wanna see if AMD goes for the best card period or best value card. Considering I have no desire to run Crysis 3 on ultra maxed out settings (not saying I wouldn't enjoy it if I had the system to do it) I look for cards that will run my games to where they looks good to me which is atleast 1080p.

I just bought a pair of EVGA GTX-680s from a friend of mine. He charged me $380.00 each for them, but also threw in a 240GB SSD too.

They are each in a i7-2600K system and both systems work as well as I would want. I'm set for a while.

I did put them together in just one of the PCs for a few days,......then I ran a few benches. It was stellar, but I'd rather have two high performing systems than one mega-fast box.

That is pretty good deal man. $380 is a good deal for one card but throwing in an SSD is icing on the cake. I like the 7850 I got currently, it runs everything I play at high settings. Really the only thing holding back my PC is the first gen i7 revision C0 I have currently. Still does well but lag is an issue sometimes when it come to CPU intensive programs. Reliability has been great though since it was bought in 09. I almost traded up for a 2600k but I didn't want to buy a new mobo.

It's crazy to buy a TITAN when you can overclock the 780. It'll have similar performance as the TITAN but at a way lower price.

Nvidia has really been kicking up the competition in the GPU market. Best part is the consumers are getting more bang for their buck by AMD and Nvidia. It finally seems they are making new strides in technology by both companies.
