GT to ultra power mod done, will it work?

[reject]

its a simple mod, similaer to kamerats dual 12v lines
will this work? no caps added to card, but the psu had 2 16A lines, so now the card is only drawing half the current load from the main rail, so the cpu should get more power too right? i just soldered together the joiner

[reject]

will this work? i will try if its not gonna casue trouble pulling from 2 12v rails, since the psu is powering mobo it should make a difference right?

I really don't know, but if you go ahead please post the results. This looks interresting

I have been using that for two months, it is simple and it works....

But in the psu ALL the wires are joined again so there is no 2 separate 12 V lines... they are all the same.

But you get more current trough to the card and voltage doesnt drop so much in the card because of that double wiring....

PSU's with multiple rails are not joined internally.

ill try it, the double rails will split the load on my psu, casue the secondary rail has better volts, but will the card short out from receiving 2 many incoming currents? i dont think so, but im scared becasue of all those guys who lost their x800s using a separate psu for vidcard

[reject]

ok im running with this now and its all good. played far cry for a few hours
cant test oc till some cold weather

[HaLDoL]

Is there a chance of short circuiting you psu and maybe your card?

[Mr. Tinker]

The question is: is it more OC'able? What are the practical differences?

There is a separate thread going about this, but with a different method being explored:

Not sure but I think that was a problem because you have the lines from one PSU grounding through the card to the MB then to the PSU connected to the MB, which is bad.

i dont think ill be able to test the oc improvements till its colder or i get some better cooling, i think this mod will help cpu more than gpu tho. now it has up to 16A when before it had to share that with vc, and now gpu has 31A on 12v

[Damien]

so wait, what exactly did you do? I don't quite see what you did. It has 2 lines, did you just connect one to the other and to the video card?

[adamwinn]

he made a 2 into 1 molex connector and has one input coming from +12v1 and the other coming from +12v2

I'm not sure if I'd recommend this for long term use though - all of the 12v rails in the psu come from the same transformer, they are only divided by seperate rectifiers to keep current below 20A on each line. so whats the problem? Well if the voltages are a bit different like you said, the two rectifiers can start fighting each other... in a sense. Basically you risk civil war inside your psu with one line trying to raise the voltage on the other, and the other line trying to lower the voltage on the first, etc.

though personally, i've yet to see hard-evidence that this can happen. i was going to do it myself but i just bought a single-rail psu, so its a null point.

Now DamienKC can finally rest after receiving his answer 1 year and 2 months later.

[adamwinn]

haha woops. i totally didn't even notice the date of this thread. wow, this is graveyard material... i don't even know how i found the thread o_O

[Jochenp]

Hey, this thread has always intrigued (sp?) me
Where there any gains at all?
