The MOST POWERFULL 12V PSU EVER...

[SkylinGTR26]

MMMM.. cant wait

What is Ultra good at anyway, their PSUs suck, their ram is bargain crap, their cases are really cheap, their just not good at all...

Well keep up your 1337 work hipro5

[dietwaterrr]

Ultra is not so good at psus

You've hit the nail on the head hipro.

BTW, I agree, pictures?

Thats the past. please look at johnnyguru's site.

Subscribed to this goodness. HiPro, you're crazy.

I have Victoria Magnetics Toroids with similar specs. 14V/2000VA
they were to power a set of six Aleph-X Amps.
But since my audio focus has moved to something even more extreme(Plasma tweeters!). but lets not get of topic, Can you post the diagrams(with suitable disclaimers of Course) so that other people (such as myself) can marvle at all your engineering Glory and perhapse even build ourselves a copy

[PowerSlide]

patiently waiting for pics

[Duh]

Not patiently, just waiting piccies . I am more than convinced that you are gonna as you have been doing ever since. Not trying to pressure you up though

150A PEAK power......For a couple of seconds?....

Actually, no.

150A sustained.

Albiet rated at 25C.

[generics_user]

Actually, no.

150A sustained.

Albiet rated at 25C.

but which PSU will ever run at 25C?

all PSU manufacturers should rte their PSUs at 50C, this is more suitable for realworld-conditions (just like enermax did it with their galaxy PSU)

[Kobalt]

My solar powered car can go 2000mph....






on the sun.

[Kasparz]

Actually, no.

150A sustained.

Albiet rated at 25C.

150A sustained with Ultra? And efficiency about 50% id guess. 110v wall plug cant output 2kW anyway.

Greece have 220v,not 110v like in USA...

[Timmay]

240 in Kiwi-land... Send us down that PSU Mate

[Kasparz]

Dont worry, i know.

Some update......Unfortunately the box of it would be quite big - though I don't mind at all -
It's dimensions are U2 Rack mount (19") thus 48.2cm x 13.3cm (phase plate) and 55cm it's depth.....

I finally decided to make THREE indepented circuits for three +12V outputs.
Each +12V output will be 1000Watts REAL 24/7 power and 1300Watts peak.
Two of them will be for the VGAs and the other one, will be for the mobo....
All the other power supplies (3.3-5, etc.) will be done as described....

As for photos, I'll upload some as soon as I find some time to do so, coz I have a LOT of work to do here and not much time for my shelf to spend....

P.S. The big joke is that I've started an 1000Watts PSU only for the VGAs, and now I'm building a 5000Watts one.....

EDIT: I forgot to add that it'll have on each output voltage digital readout to show the real voltage under load or idle and off caurse full protected from overvoltage, overcurrent and over temperature.......PLUS that the 2 x 12cm x 12cm DELTA fans will not work all the time at full speed but they'll be thermaly controlled by the huge heatsink....

[komer]

wow...

[j4mes]

Make me when your done!

[kuhla]

*drool*

This is so awesome.

Soooo.... when are you going to put all these ideas into a smaller, perhaps 700w model? hehehe jk

you should probably give up on building a PSU at this point.

just go to the local power plant and lease all their equipment, get a few Megawatts...

[Pipi]

He would still need to get 12, 5 and 3.3 volts out of that so the PSU is still needed.

How come your using linear regulation? You could make FAR better use of the power from the wall by using an Industrial DC-DC converter. Plus it would be simple, but of course expensive for the DC-DC converters.

If your transformer puts out 14 volts DC rectified at the amperage your trying to do then that will be several hundred watts if not 1000 watts of power being dissipated just by the regulation circuitry. Also the capacitance that will be needed to prevent excessive ripple to the regulation circuits will be outrageous. I know linear supplies put out nice clean voltage, but is it suitable for driving high current switchmode regulation on the graphics card?

I've had problems in the past with transient response with large linear regulation circuitry driving PWM regulation. Since PWM takes power in bursts thousands of times per second plus the EMI it fed back into the linear regulation it drove the feedback loop of the linear supply nuts and caused some serious High frequency oscillation which destroyed the linear supply in several minutes. It can be done, but there are easier ways. In my case the feedback 180 degree phase shift was too low considering the frequncy of the PWM. Your linear supply is gonna need one hell of a current slew rate. large secondary capacitance can help to some degree, but then you gotta worry about current peaks during recharge causing ringing on the output.

Seams the easiest, cheapest, and most power efficient route would be to design a SMPS that directly took filtered & rectified mains AC and put out the 12v. I bet there are medical switch mode power supplies that put out a hundred or so amps of current. But then again it wold cost thousands of dollars.

Also, I have a power supply at work that was used by a very very very well known automotive amplifier manufacturer and it puts out 300 amps at 7v to 18 volts DC. It was used to test 2000 watt Class D amplifiers which are horrid for noise induction into the electrical line so a couple of video cards is no prob.

I'd definitely like to see the schematic of your regulation circuitry. A 12v Linear regulated 400amp supply is nothing to sneeze at for sure!!

Is the 5000watts you figured output power or total power from the wall?

Also for anyone wanting a dedicated hundred to 200 amp 12v power supply, they are readily available for autosound purposes. I used to use them a lot for trade shows and when I competed in DB drag racing shows. Stinger makes decent ones and Im sure there are many other manufacturers also. they are also reasonably priced considering the output.

I'm using Linear regulation for me and only.......I'm in love with one PSU of mine that I have it since 1985 and it works almost everyday testing/feeding the R.F. Linear Amplifiers (FM/TV) I make.....
Since that time till now, it works and it works and it'll keep working....
Now show me a Switching PSU that has worked OVER 20 years and STILL working with ~5 to 15mV output ripple at full load.....

Though in my constructions of my TV transposers/repeaters and FM Linear Amplifiers, I put switching PSUs.
As I have figured out all those years of manufacturing, the most (if not all) of the "machines" that come here for repairing, have switching PSUs and guess what!.....Their PSUs are died from the ups and downs of the El. power company...At 10 of these, only one or none is died with linear PSU....

As for EMI you're talking about, I'm used to it many years now coz I work with high frequencies and I HAVE to filter my "machines" VERY well for EMI and RF....

Anyways, I do like and work with switching PSUs as well BUT this one will be as I have dreamed off....

P.S. I MUST hurry up with it now coz I'm sick of having FOUR PSU for benching....One for main - Zippy 700W - one for all of my 12x12cm DELTA fans, and one for EACH VGA.....

[Sparky]

don't hurry too much though, you want it to be perfect

Talk 'bout overkill.
How thick are wires that u use for 12/5/3.3v? How much current they can handle?
You are probably best customer of Greece power station

awesome psu
