2000W power supplies appear

GRAPHICS CARDS ARE constantly demanding more and more juice, and the levels at we are looking now are pretty much unbelievable. While the microprocessor industry learned its lesson about bleeding power like a stuck pig, the graphics boys are still living in a dream bubble that power levels won't be reached. Since 80nm and 65nm graphics chips are approaching fast, there is general concern how much power next generation graphics chips consume, given the fact that the PCIe Gen2 standard will give an additional 75W, or 75x4 = 300W. If you want a multiple graphics chip configuration, you will require at least 1000 Watts at 85% efficiency.

Engineers at ULTRA and OCZ Technology worked hard on this conundrum and the final results are being launched this CES. Forget about 1K or 1100 Watt power supplies, 2000 watts is now the measure of brutal power for computer components. So these power supply units (PSUs_ have power spec equal to small air-conditioning units and just mention that the approach of these two companies is totally different

this is complete bs. why are cpu manufacturers introducing chips that are more and more efficient and video card makers are running the opposite way, someone please put a stop to the madness.

I guess they're making these for upgraders, SLIers, and CrossFireErs. They plan on putting more components or a quad, even octo SLI configuration and its working without hassle. 2k watts is going to run the Electric Bill crazy as hell, but if people can handle a large bill, so be it.

wow. And thats what a quad processor needs at least. I wonder if that would be enough when you have the processor(s) running at full for several hours (heh, and if the processor would support that work)

Base on what I fig out there way more then enougth with 2000 watts for one quad processoris, quad processoris use just under 300 watts there more the enogth for "4" quad processor = 16 cores SMP processors plus 4 SLi and 16 drive Raid setup.

LOL not only the electricity bill becomes expensive, but the computer that consumes 2kW is also VERY expensive

Actually the G80 (8800GTX) has a far far better performance per watt rating then its older siblings. Its just that it happens to pull more wattage at peak but gives drastically better performance for that extra wattage then previous cards would.

So Video card makers are making more efficient cards, its just that sometimes they need the extra power to get those massive performance jumps every generation.

this is just pure stupidity

Holy crap... Why don't companies just focus on efficiency in their products? (mainly video card companies)

my thoughts exactly...
if this goes on like this, i might start thinking in installing a power plant in my house just to get enough energy to boot a pc....
jesus christ..................

Only what it needs, to a theoretical max of 2kW, although chances are it would pop if you pushed it close enough to it's rating.

It would only pull the wattage demanded by the system up to it's rated capacity.

The 2,000 watt rating is probably a peak rating, as opposed to a constant draw rating. In this case, the 2000 watts would be the rated peak power for a given time period... Say one minute at full load. It might handle 2,100 watts for 30 seconds. And it might fail after 15 minutes at 1,800 watts.

Think of your stereo. The amplifier might be rated at 500 watts, but that level is only reached on peaks when the volume is cranked all the way to the top. The computer supply works much the same way.

If you took this 2,000 watt monster and replaced your existing power supply, your power usage would not change. Only the capacity to deliver power changes.

We use 2,000 watt supplies all the time on servers and RAID arrays. We use multiple units of lesser capacity to make this happen. This is simply putting it all in one case.

2 kilowatts... That is a lot of power just to play Halo. I suppose you could also weld metal with it.

How could it consume all the possible wattage if there is less than 2kW of material plugged to it? :huh:
Not to be an ass or anything, but the question is a bit silly

my 580watt psu is sufficient enough to run dual core cpu/ x1950xtx and 6 hdds- theres no need for these rediculous wattage psu's..

Just need to ask my power company to reroute the national grid to my house and I'll be sorted for my Quad-SLi graphics setup :cheeky:

good greif its becoming expensive to run a computer now.... wasteing 2KW per hour now?! leaving your computer on all day at that power level would run up your monthly bill fast.... at an average of 9.1 cents per KW/h (in PA) and 30 days in a month that could be an extra $100 a month on your bill... depending on usage and if your maxing out your consumption

It dosen't work that way neufuse, If your PC pulling let say 300 watt avg IDLE usage but when system gose full gaming LOAD (fully utilized) then it need lets say 450/500 watt to run everything that be all it use in tell go back IDLE nom usage mode not full 2000 watt.
Why do think all power supplies have capacitors which storage electrical energy when the energy is really called for.
Baicsly it providing you a more reliable power quality and less DC voltage drop in long run when going to FULL LOAD.

did you read what I said? I said IF pulling a full load... which last time i checked i said with "depending on usage and if your maxing out your consumption"... sheesh

Yes I did but just try point out some facts sorry
