The MOST POWERFULL 12V PSU EVER...

[hipro5]

As tittle says....

With the nowadays VGAs drawing a LOT of current, I desided to build my OWN 12V PSU so as to be "ready" for benching and capable to handle the MOST hungry VGAs ever.....

It will be a TRUE 1000 Watts 12Volts PSU, capable of providing 84 Ampers at 12Volts and a PEAK of 100 Ampers+......
1000W/12V will be 24/7 power - continues - .......

It'll also have a built in circuit for Overcurrent and Overvoltage protection of each output separate.
It'll have it's own Digital Ampers meter so as to see what the VGA's draw...
Also a thermometer as well....

It will NOT be with 4 separate 12V rails BUT with ONE 12V and all the cables will be feeded in paraller from that rail......

I'll use a toroidal transformer at 14V/1500VA output....
Pictures will be uploaded as well as the construction begin...

The day before yesterday, I made the cables of it....
They are with sillicon instead of plastic matirial, capable for higher temps AND VERY THICK.....2.5 wires used.....

I made 5 of them.....4 that will be in use and one for spare/backup.....
Also it'll have some 4pin molex outputs for ALL the fans that will be needed here and there.....



I'll be back with details as soon as I start constructing......
ALSO inputs with oppinions of yours about what else should I add too, would be welcomed......

Cool stuff hipro
Will you be mass-producing that psu?

No......it's just for me.....

[Zzzz]

Than maybe post a sketch of the circuit?

Nice idea to have built in Ammeter for currents!!

What a build-in voltmeter be of benefit, or are you planning to have quality such that you dont need one?

I`m looking forward to seeing how this progresses

haha mental a ever George. I'll be interested to see how you implement your SMPS circuit as they're quite cutting edge in the grand scheme of power engineering. Should be quite an eye opener for alot of folk - there's alot more going on inside your PSU than you think. Having seen the booster circuit I trust you'll have something good figured out. I watch with eagerness

[hipro5]

It will not be a switching PSU.....It'll be a "normal" one with huge heatsink and stuff like that.....I kinda like "old school" designs for myshelf.....I want builds to be huge and heavy.......

????

looking fwd to see this psu's results

[Moonman]

Well, that is HUGE !

I'll use a toroidal transformer at 14V/1500VA output....

Pics?

[Zzzz]

????

Please correct me if my post isn't making sense

[tiborrr]

Well, i'm starting to have some sick ideas with my mate moon to copy ur psu

[prosk8]

wow i cant white for you give 1 for me

[Okda]

Please correct me if my post isn't making sense

sorry i didn't mean anything bad

i just wanted to know the answer to ur question as for sure you do too

of-topic
ur sig is very huge :P

Oh OK

Your right... Ill cut out some parts there...

Linear design?!?! oucha thats gonna need some serious heatsinking when your pulling the amps

I suppose you can minimize losses with low voltage drop FETs and good PCB designs. Yeah this will be interesting mate.

hipro is nuts :P

[Pipi]

If this will be just for the cards, won't the PC fry if there's a voltage differwence between the cards and the mobo? or will it be for the wole system? But then you'd have to do thr 5 and 3.3 V too. I'm a bit lost here.

[heikis]

it's only for the VGA cards.

[flavoraid]

dying to see results

[prosk8]

Hipro Like How Mach Is Be Cost

[el rolio]

awwwwweeesssooooooooooooooome

[Nosfer@tu]

Hipro Like How Mach Is Be Cost

You CAN NOT buy one!

It is only for him self!!!!

With 'new' HW there won't be problems. I've run 7900GT SLI with their own PSU without any problems.
I believe that only X8xx series had problems with this. Pls correct me if I'm wrong.

Phase cooled maybe ?

[lalPOOO]

Good idea George!
Plus, this way you won't need to build a bigger one for a couple years
