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.

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.
*thinks*
Quad GPU, Dual Quad-Core, 4x15k RPM RAID, and maybe a built-in toaster?
I agree, 2000W for a PC is wasteful - legislation should be made to stop PC manufacturers passing a certain rating.
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.
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!
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:
There is more info on the Ultra power supply. Malware posted an article about this a few days back. This thing is no vacuum cleaner, or oven, or whatever else you what to compare it to. This thing is a real beast.
Which would you go with?
