WEBVTT

00:00:00.520 --> 00:00:06.759
well I'm going to have to actually edit this vid video together a little bit but

00:00:04.400 --> 00:00:12.240
this is going to be my final video about the power consumption of the GTX 480

00:00:10.080 --> 00:00:17.480
four-way SLI you can see my cards are slightly overclocked here but not not by

00:00:15.240 --> 00:00:25.199
a tremendous margin and here I'm going to take a baseline idle temperature

00:00:19.880 --> 00:00:28.000
reading so I'm at 67 65 69 and 63° on

00:00:25.199 --> 00:00:31.720
all four cards and uh what I'm going to do is I'm going to run 3D Mark Vantage

00:00:30.000 --> 00:00:36.600
along with a couple instances of prime 995 in the background and the cat is

00:00:34.440 --> 00:00:41.320
moving the projector don't do that here get it get away from there found a mouse

00:00:39.840 --> 00:00:46.039
well it's not a real Mouse it's like a toy mouse but go play with it over there

00:00:43.800 --> 00:00:49.559
okay so um yeah those are my Baseline temperatures and we're going to have a

00:00:47.680 --> 00:00:53.719
closer look with 3D Mark Vantage running with a couple instances of prime 95 in

00:00:51.399 --> 00:01:00.440
the background I think you will find the results quite

00:00:56.879 --> 00:01:03.160
um interesting the Jane Nash test covers

00:01:00.440 --> 00:01:06.799
between about 900 watts to about 1100 Watts you can see the uh she's getting

00:01:04.720 --> 00:01:10.920
in the boat right now so it's sitting at about 1,000 Watts from the wall and uh

00:01:09.439 --> 00:01:16.159
this one there's kind of a funny thing that I that I want to show you here as

00:01:13.520 --> 00:01:18.799
the plane starts to take off the fans ramp up on the video cards check this

00:01:17.720 --> 00:01:21.159
out I don't know if you'll be able to hear it or

00:01:23.079 --> 00:01:30.079
not happens every time in that particular Benchmark but uh the new

00:01:28.280 --> 00:01:34.240
Calico one is actually the one that I see a little bit more power consumption

00:01:32.000 --> 00:01:37.960
on and uh while I'm waiting for that to load why don't I talk a little bit about

00:01:35.720 --> 00:01:42.399
the heat output this system pretty much instantly heats up

00:01:40.840 --> 00:01:47.119
the room I'm in here so I'm just going to kind of stand in the center and look

00:01:44.520 --> 00:01:52.880
around so you can see about how big this room is and you can pretty much forget

00:01:50.320 --> 00:01:57.479
about gaming with the door closed if you have a system like this as soon as you

00:01:54.920 --> 00:02:02.360
flip the switch on some kind of 3D application it gets hot

00:02:00.439 --> 00:02:07.439
so you can see new Calico is already up around 1200 watts I've seen this one

00:02:04.399 --> 00:02:09.560
Peak as high as about 1300 Watts but

00:02:07.439 --> 00:02:13.360
just on the topic of heat again really quick here I just want to talk a little

00:02:11.640 --> 00:02:17.840
bit about uh what's going on at the back of the system so from here I mean I can

00:02:15.879 --> 00:02:21.239
feel the heat uh being blown out the back of this case it's about like a

00:02:19.080 --> 00:02:24.879
space heater from a distance like this and then even the heat pipes that don't

00:02:22.640 --> 00:02:28.360
have any active air flow pushing the heat away from it I can feel it

00:02:26.400 --> 00:02:32.360
radiating off there at about probably 5 6 in away and even the stickers that are

00:02:30.920 --> 00:02:37.680
on the back of these video cards have been all peeled off just by operating

00:02:35.480 --> 00:02:42.319
for uh for a couple days here on the weekend so let me see what our power

00:02:39.920 --> 00:02:46.879
consumption is like now yeah so we're sitting at about 930 W so basically the

00:02:44.599 --> 00:02:54.120
worst case scenario I've seen is around 1 12200 1225 Watts or rather sorry 1300

00:02:50.959 --> 00:02:56.480
1325 Watts so even like that you're only

00:02:54.120 --> 00:03:02.519
actually pushing about 1100 WT DC you've got about 400 WS to spare on this 1500 w

00:03:00.080 --> 00:03:06.000
Silverstone Strider uh modular power supply and I'm just going to exit The

00:03:04.000 --> 00:03:09.959
Benchmark now so that you can have a look at the actual card temperatures Now

00:03:08.799 --> 00:03:15.360
understand this is a little bit of a warm room but that's the reality of it

00:03:13.319 --> 00:03:21.159
is if you're if you're running these cards and you're not outside it's a warm

00:03:18.959 --> 00:03:27.159
room so you can see that we peaked around 87° on the top one 88 on the next

00:03:24.280 --> 00:03:30.760
one 88 and then 90 so that bottom one which doesn't have the uh the proper

00:03:29.159 --> 00:03:35.159
ventilation slot actually doesn't get that much hotter but um it does get a

00:03:33.599 --> 00:03:40.920
couple degrees hotter than the other cards so thank you for checking out my

00:03:37.439 --> 00:03:42.799
series of videos on the GTX 480 four-way

00:03:40.920 --> 00:03:48.959
SLI I'm going to go ahead and tear this system down now but it was definitely

00:03:45.239 --> 00:03:51.480
fun and uh maybe I'll play with it a

00:03:48.959 --> 00:03:55.360
little bit more before I uh before I completely tear it apart oh yeah one

00:03:54.079 --> 00:03:59.879
other thing I wanted to say right with that 400 WTS of extra capacity this is a

00:03:57.840 --> 00:04:04.120
pretty barebone system I've only got three dims of memory in here I haven't

00:04:02.120 --> 00:04:08.000
got any hard drives I'm just running like one SSD so you throw like you know

00:04:06.519 --> 00:04:11.319
five or six hard drives in there a couple Optical drives some more RAM

00:04:10.400 --> 00:04:15.799
you're still going to be quite comfortable but this system is like I

00:04:13.439 --> 00:04:20.359
wouldn't even use a 1200 W power supply to power this anything less than the

00:04:17.720 --> 00:04:25.000
Silverstone Strider 1500 which is one of the only such power supplies on the

00:04:22.639 --> 00:04:28.360
market is pretty much what I'd recommend and uh that was a big part of the reason

00:04:26.680 --> 00:04:32.000
why I asked Silverstone if we could uh feature them in this video are in this

00:04:30.199 --> 00:04:36.440
series of videos so thank you for checking them out and now I'm actually

00:04:33.880 --> 00:04:41.639
done and yeah obviously in any warm area there's bound to be cats lurking about
