Well my regular AX1200 was $299 but it really depends on what exactly you are getting with the power supply and just how much of an improvement it is to justify that kind of increase in price.

If you can afford system witch can to use 80% this PSU power so its just quite small price :)

P.S. Waiting for lower power models with digital control system and solutions from such companies like Enermax or Antec :)

You obviously don't have a need for this type of hardware if you're asking this question. :shadedshu For those of us who do, it'll be a great addition to this relatively small high-end market.

You have a 1200w PSU for 2 HD6950s?

You obviously don't have a need for this type of hardware if you're asking this question. :shadedshu For those of us who do, it'll be a great addition to this relatively small high-end market.
Quad SLI GTX680 or Quad XFire HD7970s anyone?

How so? dual 4870X2's draw more power and you can run those along with water cooling, a highend CPU and multiple hard drives on any good 850W unit.

Quad SLI GTX680 or Quad XFire HD7970s anyone?
Again why...? They don't pull anything to what that PSU can output. Like was said these parts are quite a bit more efficient than models of old. Want to load a PSU get three GTX480's and even then the 4870X2's give them a run for their money.

You do realize that PSUs perform best at around 50% load right?

You would most definitely need a 1200w PSU for 4x HD7970s. Just one alone consumes close to 230w

Originally i was looking at 2 gtx 590's or HD6990's but in the end i went with the cheaper option so I would eventually be able to get a good laptop for college but anyway its a great quality PSU and even when it degrades it will be more than enough to power most setups especially moving forward with cards taking less power.

You do understand to get 80+ certification they have to perform well at many different loads. On a good powersupply 20/40/50/60/80% loads are within 1% of each other if your super efficient system thinks 1% is a huge difference you should really look into how long that powersupply will take to pay for itself. At less than a watt of difference I would say long after the powersupply is gone.

The other thing you should probably find out is at peak the 7970 only pulls 190 watts. Each card added will cause all cards to pull less and less wattage. I would be honestly surprised if a quad 7970 set up pulled more than 600w which happens to be quite a bit less than the measured consumption of dual GTX 295's or dual 4870X2's both of which pull in the 700w range according to many reviews and personal ownership of both setups along with many other quad GPU configs. Just FYI the recent review of the 7990 conforms to that with peak power consumption at ~300w.

Meh, modern computers are so effective in powering up and down so it's hard to say how big the load is exactly. All you can do is avarage.

The other thing you should probably find out is at peak the 7970 only pulls 190 watts. Each card added will cause all cards to pull less and less wattage. I would be honestly surprised if a quad 7970 set up pulled more than 600w which happens to be quite a bit less than the measured consumption of dual GTX 295's or dual 4870X2's both of which pull in the 700w range according to many reviews and personal ownership of both setups along with many other quad GPU configs. Just FYI the recent review of the 7990 conforms to that with peak power consumption at ~300w.
7970 Ghz ed peaks at 238W in your link. Here an actual 7970 crossfire peaks at 380W and here a quadfire system draws nearly 900W (during 3dmark11 as I understood it, could be wrong though, here it draws 979W during Furmark). Play with overclocking and 1200W will not be enough anymore.

Very very limited market, yes, and many people buy more powerful PSU's than they actually need, but there is a point to those units.

That is full system draw at the wall meaning that it only actually pulls around 850w if we use their ~87% efficient power supply from the review. 850w draw peak is fine on a good 850w unit which will be rated for 850w continuous at 50C. The reason I linked to w1zzard's review is other reviewers measure at the wall for a system without a video card and then with not a very accurate benchmark as far as I am concerned.

Yes I know ( I think I said it was full system? but nvm :p). Which is also why I said if you're overclocking 1200W will not suffice. And again, the majority of people do not need it, but there are those who do. I mean go for dual socket, fill up the PCIe slots with big nasty cards, overclock and do some serious work with them and you need all the power you can get.

He is overclocked.



The added power draw of 100-200mhz on the video cards still isn't enough to cause an issue with any GOOD 850w remember those units are rated to a peak of 1000w.

My 7950's, Gigabyte Windforce edition, in Crossfire, at stock, pull about 235 W. BOTH CARDS.

Total system power consumption is literally 4 W away from 400 W. Stock speed of the cards is 900 MHz.

OC to 1200 MHz, a 33% OC(I know, killer OC capability on these GPUs), power consumption for hte card NEARLY TRIPLES, and the full system pull 836 W.


That's jsut two cards, and actually, I've been told my cards clock really well.

That's with a 3770K, 4.6 GHz, which pulls jsut under 100 W. You can figure ~75W for the board.


With a 3960X @ 4.6 GHz,(CPU voltage just 1.275 V), power consumption at stock is 498 W, which increases to 950 W.


And that is not having the cards maxed out...that's just 1200 MHz on the GPUs, no memory OC, and my GPUs can go higher.

850 W barely cuts it, depending on the rest of the system. And, i have killer 3770K (4.6 GHz @ 1.2V or less) and 3960X chips...most CPUs will pull signifigantly more than mine...I've seen very similar 3770K, for example, needing 1.225 V for 4.6 GHz, pull 20 W more than my chip.


I used to recommend 850W unit for dual GPU, 1200 W for three or four, but today, I have a hard time doing so. I am sure htere are going to be many instances where such PSUs will not be enough to max out the system. BOth nVidia or AMD...they got some killer chips with huge OC potential on both sides.

Total system power consumption is literally 4 W away from 400 W. Stock speed of the cards is 900 MHz.
These two don't really make sense to each other if full system power consumption is 396w how can each card pull 235w

OC to 1200 MHz, a 33% OC(I know, killer OC capability on these GPUs), power consumption for hte card NEARLY TRIPLES, and the full system pull 836 W.
Again your math is way off. 235w*3=710w*2 cards=1420 watts.


That's with a 3770K, 4.6 GHz, which pulls jsut under 100 W. You can figure ~75W for the board.
I would guess a lot closer to 50W for an ATX board.

With a 3960X @ 4.6 GHz,(CPU voltage just 1.275 V), power consumption at stock is 498 W, which increases to 950 W.
Power consumption of what? The entire system? In what? Furmark or a real life? If all of your posts are simply Furmark I could honestly not care. Nothing in real life will ever cause the card to consume that.

I used to recommend 850W unit for dual GPU, 1200 W for three or four, but today, I have a hard time doing so. I am sure htere are going to be many instances where such PSUs will not be enough to max out the system. BOth nVidia or AMD...they got some killer chips with huge OC potential on both sides.
Well according to your numbers we should probably all start investing in these...

These two don't really make sense to each other if full system power consumption is 396w how can each card pull 235w



Again your math is way off. 235w*3=710w*2 cards=1420 watts.




I would guess a lot closer to 50W for an ATX board.



Power consumption of what? The entire system? In what? Furmark or a real life? If all of your posts are simply Furmark I could honestly not care. Nothing in real life will ever cause the card to consume that.



Well according to your numbers we should probably all start investing in these...

Dude he is talking about overclocking. Cards that are overclocked the power consumption can easily increase about 50-75% even double if you push it far enough. And this i just hte video cards. Processors and the rest of the system consume power as well. WE all overclock out CPUs except for maybe Mailman and some others and those consume even more when clocked as well. I would never use a 850w PSU if I were to run 3 or more cards. If I were to run 2 GTX680s that would be fine I would think. But even then, PSUs perform at their best when they are only at load from 40-60% across the board.


I would never want my PSU pulling 1000w. Efficiency then would just go through the damn floor, and I don't want that. Im all about power efficiency when it comes to my PSUs.

Trust me I have probably clocked a few more cards than you would think. Without heavy voltage modification please tell me how you plan on turning a 230w card into one that pulls 460w+.

Pretty damn simple equation for power consumption of any processor CPU/GPU/APU...

CPU Overclocked Watts = Default Watts x ( S0 / S ) * ( V0 / V ) ^ 2.

Where,
S0 = Overclocked Processor Speed,
S = Default Processor Speed,
V0 = Overclocked Processor Vcore Voltage,
V= Default Processor Vcore Voltage.

You can think what you want I will continue to run my heavily overclocked rig with a simple little 850w continuous unit.

LOL,

yeah with efficiency at 50% :laugh: :rolleyes:

No with 80+ bronze certification I would bet you money its right around 82% at 100% load. I also have enough PCI-e connectors for 3 of these new cards or dual dual GPU cards which pull the same wattage.

Don't be an ass. I said BOTH CARDS. Yes, each card was only pulling roughly 120 W/


Again your math is way off. 235w*3=710w*2 cards=1420 watts.
Again, no, your reading comprehension is what is at fault...perhaps I could have typed it out a bit more specifically.

I would guess a lot closer to 50W for an ATX board.
The 40-something boards I have sitting here next to me say 70-75W. a Few boards a bit more, but not much. Yes, I test every single board I review. One a week, now, 12 in the past 3 months alone, and those are just the posted reviews.


Power consumption of what? The entire system? In what? Furmark or a real life? If all of your posts are simply Furmark I could honestly not care. Nothing in real life will ever cause the card to consume that.
FUll system, in BF3, which draws the highest power out of all the games I play. I know you've been gone for a few months, but if you pay attention a bit, you'll see that we have a pretty large community of BF3 players here, and I play BF3 with them daily.

Furmark? Please.

Did you forget I do motherboard and memory reviews here for TPU? I am very very careful in what I post, specifically because of that. I fully expect users to verify what I say on my own, and accept that as fact. Using furmark...that's stupid. Just outright stupid.

Actually, yes, if you want to get the maximum out of any system, and you can provide ample cooling, 1200 W is NOT enough. Just ask any real extreme multi-GPU bencher how many PSUs they use, and also notice PSUs like EVGA's new one, having functionality built right in so that it can be daisy-chained with other matching units.

3960X pulling 450W? 8150 pulling 450W as well? YOU BET. It takes LN2 or similar to remove al lteh heat fast enough, but it's definitely possible.

MY bad 3960X pulls up to 155W stock, and that's not counting VTT power.

It's no big deal.


BTW, your math for overclocked silicon is WRONG. there is not a single formula that applies, as silicon quality differs form chip to chip.

For example, my 3770K draws 90W-100W @ 4.6 GHz. Erockers pulls about 120W. Those two chip prove your math wrong.

Default Watts? There is no such thing reported by CPU OEMs. They report TDP..which doesn't refer to power drawn..it refers to cooling needed.

I'm sorry ,CDA, but your knowledge here, fro mpast hardware, doesn't apply today. Technology is very differnt now, than it was even just two years ago. You really should invest in a newer system and see the differnces for yourself..on hte Intel side of things, it's pretty amazing, I think.

When it comes to PSU reviews you need not read other reviews if you read JG.
