It looks like that your U95 is beeing cross breed with U35?? The 4 pcs modular is exactly the same like the U35Quote:

In order to get all 80 amps out of it you'd have to make sure your cpu uses 20 amps the 2nd cpu uses 20 amps plus some sata drives to equal 20 amps. Then everything else... What a piece of crap. IT can output a lot of power but only allows 20 per rail making itso that if you can't get 20 off each rail you can't get the full power it can output. Atleast that's my understanding.

I see you never ehard of servers and workstations.
And if PSU has 4 rails 20A ea that doesn`t mean it has total 80A on 12V line ;)

Nevertheless each rail can only deliver 20 amps unless I was wrong. So wth 4 rails at 20 amps each you get 80 amps max which is what it can supply. If you can't get all the amps off each rail then your really not getting 80 amps. So therefore you must use use every single amp off each rail for it to be worthwhile. Now it doesn't have huge 5v or 3.3v rails so it's an overpowered overpriced psu in comparison to something else to power your machine. Well unless you use peltiers. Even then you can only use something up to amps so that you don't overload each rail. The combined amps of the 4 rails whether they are independent or not makes no difference... I might be wrong. it still says 20 amps on each rail. So in essence it's wasted power. Since you can't tap into it without going overspec.Quote:

It's not advertised as being single rail 80 amps though is it?
It's meant for quad SLI setups or even Crossfire, which it manages quite well.
If you want a supply for 80 amps on a single rail you'd be looking elsewhere off the bat, as this is a multi rail psu - it's advertised that way, so it's a no brainer.
Sure there are situations where one may want a single 80 amps, but for my sytem I'm perfectly content with 20 amps available on each of the four rails. I have 2 1900's in Crossfire, and they draw upto 15 amps a piece, secondly they don't interfere with my cpu rail or with the rest of the devices. So I can't see any real problems.
I'm talking about how it equates to 4 rails with 20 amps but you can't truly access all 20 amps. Thereby wasting power. So who the hell needs 1100W. I mean only the retarded people who write newegg reviews think they need one. I read a review of a guy who said that the Fortron Epsilon 700W failed to power his 7800gtx SLI because it only had 15 amps on each rail... Then he bought the 1kw PCP&C... Your X1900XT's DO NOT DRAW 15 AMPS APIECE. There is no way in hell it can draw that much. That's greater the 170W! :nono: Nothing would interfere with anything if it was all on 1 rail. Either you get enough power or you don't. There is no crossloading the 12v rail issues.Quote:

Sure it can provide 80 amps but only if you manage to find a way to use every single amp. Which I doubt is very plausible or practical for that matter. So simply your only gonna use maybe 40-50 amps with Quad SLI and Crossfire. A single 80 amps means it would have use because it's easy to access al 80 amps. I don't know how many more times I can say this. You aren't gonna get every single amp on this psu even though it can supply 80 amps. Thereby making it quite useless. Your going to have tons and tons of overhead with a huge wad of cash missing from your pocket.
I wasn't talking about a single rail anyway!
A 430W Seasonic can handle an FX-62 and a X1900XT
A Silverstone ST56ZF can handle Crossfire. And it could probably handle Quad SLI as well as long as you aren't overclocking it too much. A 7950GX2 may use 170W max I would think as they downclocked it. Now that's around 14 amps. Double that to 28 amps. Then add a 10 amps cpu if you get conroe less you could do it since the ST56ZF can handle a 38 amp load which peaks at 45amps I'm almost sure.
The 600W GameXstream could definetley handle Quad SLI. And if you are a huge overclocker the 700W would do you just fine.
So unless you are preparing for Dual R600's that take the max 300W each then it's pretty damn useless.
you talk about overhead and using the psu to its fullest potential...Quote:

so you dont blow up your 430 seasonic.
and let people give their reviews and opinions
It's easy to buy pcie to molex connectors if you want the power to go elsewhere.
Ati are bringing out a 3 pcie card solution this year, even with die shrinks the cards are hungry.
If you don't want/like the supply don't buy it.
3 X1900XT's ok that's around 33 amps give or take a bit. I overestimated too. And this is at load. An FX-62 overclocked. Say 15 amps. A few scsi drives. Say 2 amps apiece startup(not exactly sure). say 4. 4 regular hard drives. 1.5 amps a piece at startup.
so 62 amps... if you started at the same time.... A good 58+ amp psu would handle it... btw if you have such a big rig you'd might as well just buy the single rail zippy instead of this junk. And since hard drives don't even use that much spinning you might as well cut them out and just do a staggered startup. This is 80 amps... great 22 amps overhead... And then you have to try to figure out how the split up the load.
you'll be able to play bf2 AND cook your eggs at the same time!Quote:

a 600 watts supply running at 600 watts isn't going to run as well (with less heat and fluctations) than one rated for 800.
for example. i'm thinking of running three 24w pumps for the watercooling system. add to that the possibility of crossfire with an additional ppu in the future.
wow.
with a chip/drives yadda yadda...
a million fans.... keep in mind what the individual components are rated are at are just a small part of the equation.
Well there aren't many single rail psu's about are there? There is the Zippy, but how many online stores have it in stock? Least of all in the UK, lets all take the risks of always ordering from abroad shall we, that'd be great for rma simplicity when something goes wrong....
my 900w works fine, and I have the ability to re-route power if I wish.
Wow... This is super nice!
~Mike
Where is this Tagan available in UK? not OcUK though!
You can search for it on google, quite a few different vendors should have it in stock.
The rma process is handled direct in the UK and the company is great.
Also check the new pcp&c 750w (single rail 60 amps) unit, good price to, extremeprometeia have it on preorder..
Let`s keep this thread clean from personal insults, off-topic and other non-related things.
Hi Cooper,
Is it possible that if someone has a problem with a product, or an issue with it's specs they should start up a seperate thread elsewhere?
It would at least keep the tit for tat away from the USERS impressions, rather than the opinions and views of someone who does not even own the product.
regards
Raja
We have Computer related open discussions or General Hardware sections for that.
Beautiful!!!
But for now I can only dream a PSU like this:(
Too many expansive:(
I am discussing this product. It's the review section. I say it's quite useless due to rail distribution. Noone has yet to prove to me that the rail distribution is effective and the power is needed.Quote:

It seems to me that just because I do not own a product I shouldn't talk about it. However I doubt you own this 1100W psu. I think we are allowed to disagree in this thread. I mean if we didn't then what is the point? So people can say "it's a beast" and I can't disagree?
Cooper it's up to you. I mean I never insulted someone first unless they posted complete lies or insulted me first. If we aren't allowed to express our opinions in this thread what's the point? just to say "good review, oh it's great, awesome, etc..." Cause in all honesty that's as useless as this psu.
no-one ever wants to use every amp their supply can provide, that would mean running it at it's limits..
see Cooper, here we go again..
I pm'ed cooper a very very very long post of what I'm talking about among other things.Quote:

Set amount of amps? What? It's not even the fact that we don't want to use it all. IF lets say one day in the future this power supply is still running and I need those 80 amps I want to be able to use them. But withthis power supply the reality is in most situations it will say only supply 60 amps. Which then you might as well buy a power supply that supplies 60...
The rail distribution is flawed. Tell me how it isn't.
we get your point about the rail distribution. (i agree)
its why i purchased a zippy 850.
HOWEVER,
power to spare is something many ppl want. especially when building a (powerfull) computer.
as for buying a 60 amp psu if you only need 60 amps....
think of it this way. say you want to do the quarter mile in 20 seconds....
you buy a car that does it full out in 20 seconds. (honda civic let's say)
it'll be able to do it but you'll be revving the engine to redline on every shift and using every component to its maximum capabilities.
eventually. that car will breakdown due to wear and tear.
now.... imagine you still need to do that quarter mile in 20 seconds. since you know that even if a honda civic can do it, you decide to purchase a car that can "easily" run that quarter mile in 20 seconds. (
(you buy a corvette)
what you end up with is a car designed and manufactered with higher performance in mind and thus, will be able to handle that 20 seconds quarter without much stress on the components.
it will last longer, you'll have peace of mind and chances are....
you'll be able to drink a coffee on the way down.
Thanks for seeing my point of the rail distribution!
I see your point of the car.
However the price vs performance ratio does not justify it's cost especially with crap like a leather case... wtf?
How can this be reccomended or even be that great if other power supplies are within it's price range and can supply more power than it can due to the rails?
That's why I'm saying it is useless...
