00:00:05.759 --> 00:00:11.639
the Corsair carbide air 540 High airflow Cube case is great for air cooling or

00:00:10.120 --> 00:00:16.320
liquid cooling check the link in the video description to learn more welcome

00:00:14.120 --> 00:00:23.320
to my unboxing and overview of the GeForce gtx780 direct cu2 OC from ASUS

00:00:21.920 --> 00:00:30.320
so let's go ahead and see what they have to say for themselves on the front of the Box anyway 20% cooler vastly quieter

00:00:28.279 --> 00:00:33.160
and this we believe because like the last ASUS card overview we did we have

00:00:32.160 --> 00:00:40.039
already taken it out of the box and we've already run it through the paces so yes we believe it OC Edition okay

00:00:37.440 --> 00:00:43.600
it's not overclocked much but the advantage isn't necessarily in the

00:00:41.480 --> 00:00:48.800
factory overclock but rather in the fact that because of the design of this

00:00:45.800 --> 00:00:51.399
particular card it runs more efficiently

00:00:48.800 --> 00:00:57.840
and runs cooler which allows GPU Boost 2.0 which remember reacts not only to

00:00:53.960 --> 00:01:00.280
power thresholds as well as uh clock

00:00:57.840 --> 00:01:05.159
speed but also to temperature so allows GPU boost 2 to dynamically increase the

00:01:03.000 --> 00:01:10.640
clock speed of this graphics card it's using a fully custom PCB so that

00:01:08.280 --> 00:01:15.600
includes their Digi plus power so that's their vrm design as well as their sap

00:01:13.920 --> 00:01:19.840
components so super alloy power components this gives effectively better

00:01:17.920 --> 00:01:25.280
overclocking when you use their GPU tweak software which works with any ASUS

00:01:22.840 --> 00:01:29.759
graphics card particularly this one because we found it works very very well

00:01:27.840 --> 00:01:33.840
so one of the things that ASUS has done with with this card is they have moved

00:01:31.640 --> 00:01:40.159
away from something that's been a bit of a staple for

00:01:35.600 --> 00:01:43.320
them whoa that was fun um and that is

00:01:40.159 --> 00:01:45.920
the triple slot design of their very

00:01:43.320 --> 00:01:50.320
high-end cards this is a dual slot card but hold on I'm getting ahead of myself

00:01:47.439 --> 00:01:56.200
it comes with an SLI Bridge it comes with a dual six pin to8 pin adapter and

00:01:54.079 --> 00:01:59.320
it comes with their GPU tweak and Driver which you should ignore and download the

00:01:57.520 --> 00:02:03.719
latest off NVIDIA.com and ASUS's own website as as well as a quick start

00:02:01.719 --> 00:02:07.360
guide so let's look at the card physically now it'll be obvious to

00:02:05.439 --> 00:02:10.479
anyone who's seen a reference 780 that this isn't one but let's go through a

00:02:09.239 --> 00:02:14.680
few of the things that make it non- reference number one it has a back plate

00:02:12.599 --> 00:02:17.760
so this back plate doesn't contribute much to cooling let's be honest with

00:02:16.319 --> 00:02:22.720
ourselves but what it does do is it looks cool and other than that it

00:02:20.720 --> 00:02:27.200
prevents sagging so it actually makes the card more rigid and less likely to

00:02:25.000 --> 00:02:31.440
floop down like we've seen with heavy graphics cards in the past now I me

00:02:29.879 --> 00:02:35.400
mentioned already the dual fan configuration and dual slot

00:02:33.200 --> 00:02:39.120
configuration but there are some other special things about it so number one is

00:02:37.440 --> 00:02:44.760
check this out this is their new cooltech fan design so instead of just

00:02:41.959 --> 00:02:49.519
being focused on blowing air down into the heat sink fins you can see as Seuss

00:02:47.440 --> 00:02:54.519
has built up the cooler around the outside edges of the fan so you can see

00:02:52.000 --> 00:02:58.519
there are aluminum fins here and and this fan is designed to not only blow

00:02:56.080 --> 00:03:04.040
down but also out so that means you're able to take to make better use of the

00:03:01.680 --> 00:03:07.440
heat sink fins that are all around the fan now the secondary cooling fan the

00:03:05.920 --> 00:03:13.599
one that doesn't sit directly over top of the GPU uses their more traditional

00:03:10.720 --> 00:03:17.760
style now the cooler itself in order to even have get any benefit from more air

00:03:16.319 --> 00:03:22.440
flow okay any cooler can get benefit from more air flow whatever I'm trying to segue here all right so the cooler

00:03:20.640 --> 00:03:28.280
itself has another unique feature check this out that right there my friends is

00:03:24.560 --> 00:03:30.599
a 10 mm heat pipe this is the largest I

00:03:28.280 --> 00:03:34.920
have ever seen on a graphics card uh MSI's old superpipe marketing that I

00:03:33.000 --> 00:03:40.560
don't really see them using Much Anymore referred to 8 mm heat pipes of which

00:03:37.760 --> 00:03:45.959
this card has two so there are two 8 mm heat pipes one 10 mm heat pipe and then

00:03:43.280 --> 00:03:51.040
it looks like two 6 mm heat pipes so there are five total heat pipes carrying

00:03:47.959 --> 00:03:53.519
heat away from the GPU core to the

00:03:51.040 --> 00:03:58.840
massive cooler on the rest of this C now speaking of massive coolers there is a

00:03:55.799 --> 00:04:00.920
very very very small P PCB extension

00:03:58.840 --> 00:04:05.040
right here but but it doesn't add a significant amount of overall length to

00:04:03.079 --> 00:04:11.439
the card not like we see with cards like the GTX 7 or the GTX 670 where it has

00:04:09.120 --> 00:04:16.400
like a massive plastic overhang that isn't actually part of the components

00:04:13.720 --> 00:04:19.680
there are LED indicators for the PCI Express slot so you can actually

00:04:17.880 --> 00:04:24.560
diagnose if there's any kind of a power delivery issue with the board itself and

00:04:22.240 --> 00:04:28.840
it has full support for VGA Hotwire so this right here is a PCI Express 3.0

00:04:26.520 --> 00:04:33.759
interface nothing to do with VGA Hotwire except that if if you put that interface

00:04:32.120 --> 00:04:38.120
into a supported ASUS motherboard generally speaking it's their Rog boards

00:04:35.800 --> 00:04:43.479
you can actually overvolt the GPU and various components on the video card in

00:04:40.600 --> 00:04:47.600
ways that NVIDIA never really intended ASUS doesn't advertise this feature on

00:04:45.600 --> 00:04:54.000
their boxes because NVIDIA doesn't like it but there you go the feature is there

00:04:51.120 --> 00:04:58.120
I have confirmed it it is supported now speaking of supported features it's got

00:04:55.639 --> 00:05:03.520
support for 3D Vision surround with two HDMI outputs and

00:05:00.199 --> 00:05:05.199
uh two two HDMI two DVI outputs an HDMI

00:05:03.520 --> 00:05:08.160
output and a DisplayPort output you're going to get a little bit of exhaust out

00:05:06.680 --> 00:05:11.360
the back of the case but generally speaking this is an internal exhaust

00:05:10.520 --> 00:05:18.319
card so you're going to want to make sure you have good case air flow it has two SLI connectors with full support for

00:05:15.199 --> 00:05:20.199
NVIDIA SLI up to three or even four-way

00:05:18.319 --> 00:05:24.319
however four-way just really isn't that recommended these days at the back of

00:05:22.120 --> 00:05:28.919
the card you've got two PCI Express connectors one of them is a six pin and

00:05:26.560 --> 00:05:32.199
one of them is an eight pin and then other than that that's it for

00:05:30.720 --> 00:05:37.840
connectivity what more did you guys really want were you expecting it to have like you know an anchor Port so

00:05:36.120 --> 00:05:40.919
that you could actually use it as an anchor because it's quite heavy and

00:05:39.319 --> 00:05:45.960
there's a good reason for that because in terms of the actual overall heat sink

00:05:43.960 --> 00:05:50.720
Mass available for dissipating Heat this thing has about double what a stock GTX

00:05:48.759 --> 00:05:54.919
780 does now we were a little bit worried about the complexity of removing

00:05:53.000 --> 00:05:57.880
the graphics card cooler from this card but part of what auss I mean just

00:05:56.680 --> 00:06:05.000
looking at all these little screws that it seems like we can't access but part part of what isus takes pride in with

00:06:01.120 --> 00:06:07.280
their direct CU cards is this easy

00:06:05.000 --> 00:06:12.880
disassembly four screws on the back of the GPU right there and that reveals the

00:06:10.319 --> 00:06:16.360
direct contact copper heat pipe so you can actually see the nickel plating

00:06:14.240 --> 00:06:22.520
isn't even on this part direct copper to GPU you can see that 10 mm heat pipe

00:06:19.560 --> 00:06:27.919
those two 8 mm heat pipes as well as those two 6m heat pipes all branching

00:06:25.400 --> 00:06:32.400
out to various parts of the cooler itself here all right so you can see why

00:06:30.639 --> 00:06:36.840
that primary fan is considered the primary fan as well because most of

00:06:35.080 --> 00:06:41.000
where ASUS is carrying the heat so that 10 mil pipe is right here under the

00:06:38.360 --> 00:06:45.319
primary fan this 8 and this 6 mil are sitting right under the primary fan as

00:06:42.919 --> 00:06:50.440
well as any heat that is carried through conduction directly by this block of

00:06:48.400 --> 00:06:54.240
copper and aluminum here will sit directly under that fan as well so the

00:06:52.120 --> 00:06:59.199
secondary one is only really getting some of the 10 ms heat as well as 16 and

00:06:57.319 --> 00:07:04.199
18 both of which are carrying heat quite far away from the GPU which does reduce

00:07:02.240 --> 00:07:08.000
their effectiveness now that we've got the cooler off we can also see part of

00:07:06.319 --> 00:07:15.240
what makes this card tick now this is an overclocked card a referenced GTX 780

00:07:11.280 --> 00:07:17.960
only gets uh a clock speed of around 863

00:07:15.240 --> 00:07:22.879
900 for Boost and this one's at$ 889 941 however there's more to it than that

00:07:20.639 --> 00:07:26.280
because of so here's a vrm heat SN as well as their super alloy power

00:07:24.240 --> 00:07:29.879
components but the advantage that this card gets is because it's more efficient

00:07:28.039 --> 00:07:35.680
and stays within its power Lim limits more effectively it actually is able to

00:07:32.000 --> 00:07:38.360
achieve around 1,32 MHz typical boost

00:07:35.680 --> 00:07:42.319
clock on average from what Aus has seen without any overclocking that means even

00:07:40.080 --> 00:07:47.879
at stock speeds this card should be faster than what they're really saying

00:07:44.680 --> 00:07:49.639
about it on the box which is very very

00:07:47.879 --> 00:07:55.000
cool let's go ahead and show you the rest of the components that are on the

00:07:51.120 --> 00:07:57.199
PCB itself first of all Matt PCB so ASUS

00:07:55.000 --> 00:08:02.840
two thumbs up good job guys you guys rock 3 gigs of 6 G

00:08:00.039 --> 00:08:08.000
um six G six three gigs not six gigs I was I had Titan on the brain there 3

00:08:04.800 --> 00:08:10.039
gigs of 6 gz gddr5 memory so that's

00:08:08.000 --> 00:08:14.599
pretty much the same as any other GTX 780 however it is also getting the

00:08:12.360 --> 00:08:21.000
benefit of their digital power delivery in much the same way that the GPU itself

00:08:18.280 --> 00:08:25.159
does so I think that pretty much wraps it up except what does all this mean in

00:08:23.639 --> 00:08:28.560
the real world I just gave you a whole bunch of ASUS marketing speak but does

00:08:26.879 --> 00:08:33.880
this card actually overclock better than a reference card boom here's a couple

00:08:30.759 --> 00:08:36.080
graphs so in our experience yes we were

00:08:33.880 --> 00:08:40.399
actually able to overclock the direct cu2 card better than we were able to

00:08:38.560 --> 00:08:45.120
overclock our reference card your mileage may vary it's possible we got a

00:08:43.039 --> 00:08:50.279
fantastic direct cu2 although ASUS tells us ours is pretty average it's possible

00:08:47.680 --> 00:08:54.200
that we got a bunk GTX 780 reference card however when NVIDIA seeds those

00:08:52.360 --> 00:08:58.160
cards to reviewers I don't think they pick all the bunk ones to send to

00:08:55.839 --> 00:09:01.040
reviewers so take it with the grain of salt but that's what we think think

00:08:59.600 --> 00:09:04.480
about it leave us a comment under the video what do here's what I want to know

00:09:02.959 --> 00:09:09.160
what do you think ASUS could have improved about the GTX 780 direct cu2

00:09:07.399 --> 00:09:15.200
for me they've addressed the triple slot issue which was a problem for me they've

00:09:12.680 --> 00:09:19.640
I mean yeah okay what what could be improved also like the video guys share

00:09:17.480 --> 00:09:25.809
