That is one hell of a X-Mas gift :) i wish that Santa gives me such presents :D

VERY nice work! I was just wondering if this PSU is related to the master in any way ? Seeing as you share a name with it. It came out of my new Xeon server. :cool: Little beast if 650w and is powering a quad core xeon with 4tb of disk space and is like the size of my hand!. Such a good PSU could only be made by 1 person :eek: :eek:
Bob - i've got a 235w HIPRO in my room that ran circles around 350w units back in the day lol ;)
HIPRO and err HIPRO are unrelated as far as I know :p:
So its christmas day now has santa brought you anything Hipro5 or do you have to wait till the new year?
And merry christmas all!
he didn't specify the year of the christmas :rolleyes:
Ηipro-Tech is the label used by Hipro5 in psus!
Yes we know Spyrus, we were just joking about old Hipro PSU's ;)
Amazing work. I really am interested in how the cooling is setup. At that low of efficiency (compared to regular PSUs) and that high of voltage possible, there could be quite a lot of heat produced if it was stress tested or (in the rare likelihood that any system use that much power) benched to full capacity.
Wow, I just spent an hour or two reading every single post.
Very impressed so far.
Keep up the good work Hipro, and we're all anxious to see results!
*subscribed*
my lights haven't dimmed yet, must not be finished yet;)
wow!
not only are u a master overclocker but u go past that.u engineer,design,build youurself,and produce your own stuff.that is the one of the best sounding specs for a powersupply i ever heard for computers.very good work,your mind never stops.thats a easy $600-$800 powersupply right there.pm if it is possible to special order one of these off you.im so sick of the subpar powewrsupply market.but what your thinking will make a amazing 1,000 watt powersupply,i want 1!.:up:
Thats a ton of amps :p
Cool idea Hipro5, ill watch this one with intrest.
Is this project nearing its completion??
I am very interested how it looks and performs :D
Look here.....

Hipro's little monster came in retail....
It's being sold since november 2007 i think.
Give_update
Aye, hipro man cmon, give us some updates...
Looking @ the site's spec...90a 12v... seriously?
I am not convinced that Hipro will be successful.
Example. 12v @ 100A =1200W. Now the pass transistors of such a linear regulator will require a low ripple input voltage max of 15.6V for +10% high input and allowing for a low of -10%. This represents 360Watts of heat. There is the rectifier loss of about 1.4V x 100A =140Watts. There is the transformer loss @ say 92% of 100Watts. With other losses the total would be about 700 watts. A lot of cooling required just for the one output.
Therefore for 1200Watts output about 1900Watts is required to go into the transformer. 63% efficient.
My mind boggled when it was proposed to get 2500Watts OUTPUT from two 1000VA transformers, this does not compute.
Then there is the subject of input caps they will need to be monsters to handle the 50/60hertz ripple at low voltage and provide a sufficiently low ripple that it will not reduce the margin of 3.6V across the linear regulator transistors. If ripple is 0.5V pp the 3.6V will need to be increased by about 0.3volt.
The whole reason that switching regs are much better is that the line power is rectified and smoothed at a high voltage and lower current plus the switching transistors pass a lower current at a low voltage drop ( voltage across the transistors is no longer critical) and of course the power loss is SO much less. Less critical caps and less heat.
All the above numbers are approximations but also realistic to demonstrate the magnitude of the challenge.
Exporting products is alot of work... it's too bad too. :(
Cya in a few days George... Any chance of you having this monster along with ya?
Are you aware of what the concept of "oc camp" is at the booth? I heard something about it, but couldnt quite figure what it'll be...?
I'll try to catch Danny in the morning, I'd just like to sleep long, heh.. : - )
Ohhh, and I think I'll bring an USB key along this time... I'll make you bench PiFast 4.3 - This time I'll keep whining untill you do so :p:
How on gods earth did you come to that conclusion...
240volt 4000w = 16A :rofl: so hot cables to PSU ;)
Hi George, the thread is way too long for a full read, so I hope I won't ask anything "old" now.
What about the filter capacitors? I assume you rectified your 230V with a Graetz Bridge, and if you're following with a simple pi-filter you're gonna need a huge filter capacity. That's gonna cost you more than the toroid and other stuff put together.
If you were an hi-fi addict, as I am, I would tell you "Remember about good old Nelson Pass" and you'd surely remember his DIY project, altogether with his Pass Labs commercial 30k$ hi-end class A amps, and some of his good thoughts. I don't know if you're an hi-fi addict or not, and you're used to heavy class A stuff or not, but man, really, if your rectifier is working through Graetz plus pi-filtering (LC or RC), that "C" is something I really want to see.
Good luck.
