the GTX 480 four-way SLI you can see my cards are slightly overclocked here but not not by a tremendous margin and here I'm going to take a baseline idle temperature reading so I'm at 67 65 69 and 63° on all four cards and uh what I'm going to do is I'm going to run 3D Mark Vantage along with a couple instances of prime 995 in the background and the cat is moving the projector don't do that here get it get away from there found a mouse well it's not a real Mouse it's like a toy mouse but go play with it over there okay so um yeah those are my Baseline temperatures and we're going to have a closer look with 3D Mark Vantage running with a couple instances of prime 95 in the background I think you will find the results quite um interesting the Jane Nash test covers between about 900 watts to about 1100 Watts you can see the uh she's getting in the boat right now so it's sitting at about 1,000 Watts from the wall and uh this one there's kind of a funny thing that I that I want to show you here as the plane starts to take off the fans ramp up on the video cards check this out I don't know if you'll be able to hear it or not happens every time in that particular Benchmark but uh the

feel the heat uh being blown out the back of this case it's about like a space heater from a distance like this and then even the heat pipes that don't have any active air flow pushing the heat away from it I can feel it radiating off there at about probably 5 6 in away and even the stickers that are on the back of these video cards have been all peeled off just by operating for uh for a couple days here on the weekend so let me see what our power consumption is like now yeah so we're sitting at about 930 W so basically the worst case scenario I've seen is around 1 12200 1225 Watts or rather sorry 1300 1325 Watts so even like that you're only actually pushing about 1100 WT DC you've got about 400 WS to spare on this 1500 w Silverstone Strider uh modular power supply and I'm just going to exit The Benchmark now so that you can have a look at the actual card temperatures Now understand this is a little bit of a warm room but that's the reality of it is if you're if you're running these cards and you're not outside it's a warm room so you can see that we peaked around 87° on the top one 88 on the next one 88 and then 90 so that bottom one which doesn't have the uh the proper ventilation slot actually doesn't get that much hotter but um it does get a couple degrees hotter than the other cards so thank you for checking out my series of videos on the GTX 480 four-way SLI I'm going to go ahead and tear this system down now but it was definitely fun and uh maybe I'll play with it a little bit more before I uh before I completely tear it apart oh yeah one other thing I wanted to say right with that 400 WTS of extra capacity this is a pretty barebone system I've only got three dims of memory in here I haven't got any hard drives I'm just running like one SSD so you throw like you know five or six hard drives in there a couple Optical drives some more RAM you're still going to be quite comfortable but this system is like I wouldn't even use a 1200 W power supply to power this anything less than the Silverstone Strider 1500 which is one of the only such power supplies on the market is pretty much what I'd recommend and uh that was a big part of the reason why I asked Silverstone if we could uh feature them in this video are in this series of videos so thank you for checking them out and now I'm actually done and yeah obviously in any warm area there's bound to be cats lurking about"}
