Super Flower & 8Pack Release the World's First 2kW Consumer PSU

A new record was broken today, as Super Flower announced the release of the most powerful consumer PSU ever made, the Leadex Platinum 2000W. The PSU has been allegedly developed with the collaboration of Ian "8Pack" Parry, one of the most reputable overclockers worldwide, and in association with OverclockersUK.
The power specifications of this monster are certainly impressive. It is 80Plus Platinum certified and the single 12V rail that can output up to 166.6A, implying a certain fire hazard if that current were to be drained from a single connector. It also sports a fully modular design, which is a good thing for a PSU with twenty cables. The choice of a simple dual ball bearing 140mm fan is questionable for a product with such a price tag, but it obviously is not primarily designed with low noise operation in mind.
Huge numbers are certainly impressive, but let us also remember that the power requirements of a typical gaming PC hardly are a quarter of what this monster can output. Not even highly advanced multi-GPU systems require such power. Simply put, if you own anything less than an overclocked system with four GPUs, this product has nearly zero practical value. For example, in Ian's dual X5690 system with four AMD 7970 GPUs, he pulled 1550W with some basic overclocks on a 1600W PSU, meaning that a full sub-zero OC system has room to breathe with 2000W at hand.
With computer PSUs, bigger is not necessarily better, as the efficiency of the unit peaks at about 50% of its maximum power rating and declines if the load decreases or increases. Actually, due to their design, the efficiency of most switching PSUs plummets if the load is lower than 20% of the unit's rated capacity. Therefore, buying a very powerful PSU in order to have "better performance" and "headroom" is not always such a good idea, but for those who need it, 2000W could have practical applications.

That's why he helped design this 2kW behemoth. 1.6kW wasn't enough for his needs.tim851 - Saturday, January 31, 2015 - link
It drew 1550w from the wall, i.e. including PSU inefficiency. Assuming ~85% efficiency for the 80Plus Silver PSU used in that build, the 12v power draw was closer to 1300w. And that was for maximum CPU+GPU load, a.k.a. only-ever-happens-when-stress-tested load.ipcamper77 - Friday, January 30, 2015 - link
Most space heaters in the US are only 1500W, you are going to need an air conditioner to cool the room this is used in.azazel1024 - Friday, January 30, 2015 - link
Yup. That is about 6700BTU, which means it won't be a small air conditioner either. If you vented the room right, a small fan and you could heat your entire house without turning on the furnace!azazel1024 - Friday, January 30, 2015 - link
Forgot to add, really puts my hardcore machine in to perspective. My desktop with i5-3570@4GHz and GTX750 under full gaming load pulls ~140w from the wall with an 80+ bronze PSU. This thing could supply 15 of my computer almost.ZeDestructor - Friday, January 30, 2015 - link
Meanwhile, here I am on the other end, pulling well over 600W at the wall with an (almost, according to JG.com) 80plus gold PSU. Next round of upgrades will probably push into the >750W range, and big Maxwell even further (I run dual 670s atm)...fluxtatic - Saturday, January 31, 2015 - link
How is your power consumption not dropping? Intel processors use less generation over generation, Maxwell's power consumption is stupidly low...how are you going up?ZeDestructor - Saturday, January 31, 2015 - link
Moving from LGA1155 to LGA2011-3, and GPUs aren't getting upgraded till GM200 (which I expect will be 250W a card). Then you have the overclocks, power for the fans, HDDs, watercooling pump, extra PCIe cards.Gigaplex - Friday, January 30, 2015 - link
GTX750 isn't hardcore. Isn't it powered by the PCIE bus alone with no extra power connectors?azazel1024 - Monday, February 2, 2015 - link
I was being facetious on it being a hardcore machine. It isn't super underpowered either.As for mine, it uses a 6 pin PCIe connector as it is one of the GTX750 "overclock" cards, and I am running about a 50MHz core and 60MHz memory OC on top of the factory OC (I can't recall what that brings it up to).
At least based on my math using the IGP, it actually probably could still be powered by the PCIe bus alone as it seems to only be contributing about 70w from the wall under gaming load with the rest of the system running about 70w to. Though, I'd imagine under the right set of burn load, it might be able to pull more than the 75w the PCIe bus can provide (but right now, it looks like only in the 55w range under heavy gaming load if you factor in the PSU losses).
