PSUs edge closer to 2000W


More demanding graphics cards have been the main culprit for extra power requirements over recent years, with CPUs starting to become slightly more efficient. However, both ULTRA and OCZ are preparing for the future by working towards the 2000W mark. OCZ took the approach of combining two 900W PSUs inside an enormous external chassis which connects to a smaller, standard sized unit. This results in the image you can see on the left above. ULTRA’s approach was noticeably different, using a single chassis system (larger than a standard PSU) with separate power elements for the 12V, providing 150 amps of current to anything connected to that rail, shown on the right. Because the US electric current is specified at 15A per socket, both PSUs would each need two cables when being used there, but in Europe one socket should be sufficient.Source: The Inquirer

still aint better than the pc power and cooling 750watt 60A on a SINGLE 12V rail PSU, in a review is maintained 12V exactly under heavy load, single 12v rail PSU are much better than dual rails ones

Don't know very many people who need a 2KW PSU for their PC but I guess if you need an electric arc welder in your house or office, these PSUs may be of some value. Seems to me like a solution for a need that doesn't exist.

I don't believe you'll find a better PSU than a PC Power and Cooling as they are the gold standard of the PC industry.

I have a Cooler Master RealPower 481w and my system doesn't use any more than 200w under load. Sure I have a Sempron 3400 S754 and an AGP x850 pro (three drives and a few cold cathodes). I'd like to see a few example systems that actually need that much power.
*thinks*
Quad GPU, Dual Quad-Core, 4x15k RPM RAID, and maybe a built-in toaster?

Should be a law against that much power usage for a PC, it's rather sickening. Someone needs to set up some standards and regulate power consumption in the PC world. Making vid cards that use 200+watts is out of control. I still want two of them in CF though, yes I'm a hypocrite.

It's not like there isn't stuff in your house that doesn't use more wattage. The standard lightbulb uses 60 watts. My electric teapot uses 1,500 watts. Your washer and dryer, furnace, refrigerator, TV, electric stove (if you have one), etc.. They all use copious amounts of wattage..

2KW really is insane. People don't even have a use for 1KW power supplies.

I don't know about the OCZ power supply, but the Ultra has 150A on a single 12v rail. Though personally, I think it is stupid to have any more than 40A per rail. If you are going to do more than that, and expect clean power, you have to seperate them.

I think it will allow for proper USB vacuum cleaners and ovens in the future.

I agree, 2000W for a PC is wasteful - legislation should be made to stop PC manufacturers passing a certain rating.

ultra by who ?

no doubt but single 12V rails are much better for overclocking, u can find out more on the DFI street forums, this is from pc power and cooling website:

8. ARE MULTIPLE 12-VOLT RAILS BETTER THAN A SINGLE 12-VOLT RAIL?
With all the hype about multiple 12-volt rails (ads claim that two rails is better than one, five is better than four, etc.), you’d think it was a better design. Unfortunately, it’s not!

Here are the facts: A large, single 12-volt rail (without a 240VA limit) can transfer 100% of the 12-volt output from the PSU to the computer, while a multi-rail 12-volt design has distribution losses of up to 30% of the power supply’s rating. Those losses occur because power literally gets “trapped” on under-utilized rails. For example, if the 12-volt rail that powers the CPU is rated for 17 amps and the CPU only uses 7A, the remaining 10A is unusable, since it is isolated from the rest of the system.

Since the maximum current from any one 12-volt rail of a multiple-rail PSU is limited to 20 amps (240VA / 12 volts = 20 amps), PCs with high-performance components that draw over 20 amps from the same rail are subject to over-current shutdowns. With power requirements for multiple processors and graphics cards continuing to grow, the multiple-rail design, with its 240VA limit per rail, is basically obsolete.

PC Power and Cooling is once again leading the industry. All of our power supplies now feature a large, single 12-volt rail. The design is favored by major processor and graphics companies, complies with EPS12V specs (the 240VA limit is not a requirement) and is approved by all major safety agencies such as UL and TUV.

Poeple who need more than 1KW usually do it with two power supplies.

LOL! Now I want one.

I wonder how many amps a USB oven would use. If we guess that it uses a kilowatt..
1,000W divided by 5 volts = 200 amps!

True but we have a real need for stoves,furnaces,lights and refrigerators, plus they don't run constantly. They are also rate for efficiency and are regulated heavily. I think my 27" TV only uses 120w. All these industries are focused on more efficient products.
The CPU end is pushing low power/ heat but it doesn't even come close to making up for the GPUs. With 3 DX10 cards running at full load your talking about 600w and then add in 100+ for a OCed CPU. Thats not even counting MOBO, RAM,drives,fans,lights and maybe a pump. I can easily see the need for a 1kw PSU but 2kw you would have to be powering phase change or TECs. If I had the money I'm sure I could find a use for ever last watt.
I'm willing to take donations to fund my worthy cause. For just all the money you have I can make a PC much better then yours, Please it's for the children:cry:

I'm assuming that it's this, because I can't find another that seems any more likely. The Inq doesn't give a link I don't think.

There is more info on the Ultra power supply. Malware posted an article about this a few days back.
George Ali, Vice President of Sales and Marketing for Ultra Products
In fact, most household circuits can't even provide the AC power this unit would require in order to put out 2000W of DC power.
This thing is no vacuum cleaner, or oven, or whatever else you what to compare it to. This thing is a real beast.

Thanks for letting me know - I'll leave this article because it's also talking about the OCZ PSU and has a few pictures and more details, but if anyone ever notices a duplicate news post let whoever posted it know.

of u look at the ultra 150A on 12V on that legitreviews link, it says there not sure if its on a single 12V rail

150a on 12v is 1800watts. Let alone the other rails. That Ultra may be over 2000 then.

RickyG512, lets see here, who am I going to go with here, random people on a forum that say one rail with 150A is better, or the people that make the standards and have been researching and learning about the issue for years who say that a single rail shouldn't have more than 20A?

Which would you go with?

trust me single rail is the best, didnt u read wat i copied from pc power and coolings website about single rail and posted here, its much better for overclocking too, that ultra one doest look like its a single rail, even on legit reviews they said they opened it up and it looked like 2 rails and they said they foned up ultra and the man on the phone said he doesnt know, even pc power and cooling 510 watt power supply has 34A on a single 12V rail with only 510 watts and in the review it stayed 12.00V under full load, that is rock solid, my crap psu goes to about 11.71, ive heard of some that low end ones go to 11.45V

crazy when you consider how much effort intel and amd have put into making computers more energy efficient, ati and nvidia eat more and more (yes i know ati IS amd, but theyve not co-designed yet)

Im perfectly happy with my 500W. I honestly think the 6800XT I got for christmas was overkill. If my 6800 does Doom3 on Ultra High on 1024x768 with 16X AAAF I see no need for quad cores, 8800GTX, hell even the 7950 is overkill. But 2000W... Imagine the electric bill. You would need 2 electricity providors, one for pc and one for everything else :roll:

correct me if im wrong but having a 2000 watt psu and having componnets of a total max 300 watts at load, u wont be consuming 2000 watts, its 2000 watss max it can deliver, u will be consuming 300 watts

Well, only if it was 100% efficient but you're along the right lines. It will only provide 2000W if the components inside (or outside I guess) the PC require it.

Bigger PSUs don't have as good of efficiency as the smaller ones. Besides.. If you're only going to use 300W, why not buy a 400-500W PSU?

1KW psus are about the limit. I dont forsee anything in the future going over that, or even getting near that. 750W would be all you need. Im thinking the future will bring power under control and make things more economical and environment friendly as far as power usage is concerned.
