Sorry I don't have access to High Speed downloadable content (can't watch it)....if that is power measured from the wall, don't forget to apply the 80% Efficiency ;)

So, that bring that down to around ....hhhhmmmm...800W or so....1.2 kW would be adequate, but in reality, I'm not planning on a 3rd 480...no need for it at this point, but a higher power consumption Sli (2) GPU's in the future + WC I'm confident 1.2 kW is fine

it says :

"
The methodology is simple: We have a device constantly monitoring the power draw from the PC. After we have run all our tests and benchmarks, we look at the recorded maximum peak; and that's the bulls-eye you need to observe as the power peak is extremely important. Bear in mind that you are not looking at the power consumption of the graphics card, but the consumption of the entire PC.
Our test system is a power hungry Core i7 965 / X58 based and overclocked to 3.75 GHz. Next to that we have energy saving functions disabled for this motherboard and processor (to ensure consistent benchmark results).
I'd say on average we are using roughly 50 to 100 Watts more than a standard PC due to higher CPU clock settings, water-cooling, additional cold cathode lights etc.
Keep that in mind. Our normal system power consumption is a little higher than your average system. But with multi-GPU setups .. well hehe .. that fact fades away real fast. Check it out.




....




So yeah with 3-way SLI we noticed our power consumption peak to beyond a kilowatt, 1009 Watts (!) On average however that is around 850-950 Watts. Remember that, these are peak / maximum wattages that we are showing. 2-way SLI was consuming a lot of power as well, roughly 700 Watts and that's 180 Watts more than two Radeon HD 5870 cards.

The QC problem I was talking about is the coil whine issue. The problem was supposedly fixed at the factory, but that was recently and any units currently in the channel have a chance to be defective.

Thanks for Posting that Dan...so its obvious 3 x 480's / WC and a 980X will still be fine with a 1.2 kW PSU......thats what I figured....

Thanks Zero....PM received!

no problem sir.
yup, ~275 watts per card and then some for cpu+mobo etc. furmark will add a good 25-50 more lol. was testing a g92 and it went up 20% with it.

Well.....wish I had done a tad bit more homework.....$299 for the ST 1.5 kW is an extremely good price and only $22 more than the AX.
Unfortunately my Order has already been processed, but I did send in a Support Ticket to NCIX followed by an email to Linus...hoping they can swap out the AX for the ST prior to shipping tomorrow....we'll see!

hehe. ya they should do it. Just give them a call i could say would make things alot faster, tell them you want to cancel that order, or if they can't do that then just do a refund, but now i would just go ahead to purchase the Strider since you will get the refund of the AX back for sure without any restocking fee anyways since its new and unopened. its a diff story if you paid shipping and want to swap it.

^^^ I've done this same thing a number of times with NCIX, DC and BD (especially with GPU's) ;) .....no worries!!

rjbarker, regardless if you end up with the Strider 1.5kW or AX 1.2kW, I approve of either choice, both every good PSU's.

As for you Smoothie, for what your looking at 850Watt PSU would be quite fine, no need to over buy. As far as the HX1000 goes, just because its an old design does not mean its a bad design, its an excellent design actually. While jumping "up to" an AX1200 wouldn't be a bad choice, going with an HX1000 if it would save you a bit money would still be a great choice, as the improved efficency of the AX1200 won't save you anything over time. Don't get caught up in the idea that just because something is an older model that its worse than somether newer.

The HX1000 really isn't a great 1kW PSU by current standards. It's expensive, not very efficient, and the design is somewhat outdated. There are plenty of better 1kW units on the market, including ones that are less expensive.
