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.

    "really puts my hardcore machine in to perspective -> GTX750 " I see wut u did thar!

    not completely true. The 2000W power supply is not putting out 2000W of heat.

    It is rated at 80% efficient at full load. Which means that 20% is going into heat, the rest is power.

    To make it trickier, the 2000W is rated power output, not input. 2000W/0.8 = 2500W (21 A!). Heat = 2500*0.2 = 500W.

    500W = 1706 BTU/hr. Still enough to make your room toasty in the summer.

    As you drop down from full loading, the heat output will drop less than linearly, and will never exceed 500W. That is the nature of the beast.

    500 watts are dissipated in the power supply. The other 2000 watts are dissipated by the components of the computer itself. All the power going into the power supply is dissipated as heat except any light, sound or RF energy that leaves your house.

    Yup, which actually makes my math worse as I forgot to include the bit of the power that the PSU itself is dissipating as heat, so figure up around 8000BTU of cooling required. Just a simple 1500w/5000BTU space heater is more than enough to turn my 150sq-ft bedroom (if the door is closed) about 10C warmer in just a matter of an hour in the middle of the winter. I can't imagine what it would be like having something like this sitting even in a large office running full tilt without some dedicated cooling for the room.

    Erm, every work done is converted to heat energy, that's law of thermodynamics. Even sound energy is converted to heat eventually in the enviornment. The waste heat you mentioned is within the PSU, but the GPU, CPU, monitor, even LED lights will heat up the surrounding envrionment

    You mentioned the Price Tag but no Price itself. Its at £349.99 (UK) / 369,90€ (GER).

    Hello there. Noticed a bit of uncertainty regarding the PSU cord.

    1. The PSU cord used there is a European type plug (non-UK) which is rated at maximum 13 Amps, seen though some on 20 Amps too on a 230 V supply. Basic calculus tells us 2000W divided by 230V give us a 8.69 Amps which is not too much for a normal house/socket,

    2, The UK type cord is normally 3 pin type rated at 13 Amps. So 13A by 230V means 2990W.
    More on AC type connectors can be found here http://en.wikipedia.org/wiki/AC_power_plugs_and_so...

    3. Being an electrician myself for over a decade in UK now moved back home on the old continent would advise to not worry too much about the whole thing. If the house is properly designed and built (electrically speaking) the breakers will trip. In UK the sockets ring is on a 32 Amps breaker. As long as you are not running simultaneously everything (electric kettle, vacuum cleaner and other big consumers) you are ok.
    In Europe is different, There are still load of houses which are running the sockets on a 15-20Amps breaker so you can overload the circuit easily.

    To cut the story short put yourself a dedicated circuit from the MCB board on a 32 Amps breaker using a 2.5 3core cable if you are in UK to be better safe than sorry and run your electronics/PC and this magnificent PSU.
    In Europe you can do something similar running a single line of the above mentioned cable on a 20Amp breaker and you have more than enough to run it.

    The 1 million dollar question is:
    your electrical supply is big enough to take it?
    In UK the supply on normal houses/flats (2 phase systems) are 100/60 Amps rated based on meter main incomer which should be enough.
    In Europe is a bit tricky as there are quite a few households which have still a 25-30 Amps on meter main incomer.

    Now let the lashings begun and sorry to had bother you with my babble.

    I've a PSU thought / question for all you learned people here;

    My buddy (rich, but usually a cheap barsteward) runs an ancient AMD 6-core (95W?) CPU, with a 980GTX, Sammy 840, and 1TB for storage - all on a 450W (likely high quality, forget the name) PSU.

    No problems at all.

    We noted the reviews the 980GTX drew 15W idle & 270W tortured. We added the 95W for the cpu, and knew we had enough for the rig. Why would you need more if driving only one of these newer cards?

    He uses this to drive his 4k TV, and the only gaming done on it, was me for 'testing purposes'. :)

    What a waste, I know, I know.

    You failed to factor in MoBo, power coversion efficiencyy, RAM, HDD, ODD, USB and fan consumption. You're running it awfully close.

    I only know one thing. Mains in the US is cheaper manufacturing stitched with "white thread". Capitalists have invested in the minimum funds to build it and then they give you milked to the absolute maximum in it.
