How can i use two powersupplies in one computer i've seen people do this but i have no idea how its done, i have a Corsair HX1000 and an Enermax 1000w i'd like the corsair to just power my GFX cards
 
You just need an adapter/crossover cable to allow it, something like this

basically it does what it says. I believe it "sences" the power turned on by the motherboard and triggers both power supplies to turn on at the same time. There are a few out there, was just showing an example :)

Oh yeh, I dont think I would do the above posters link with my system, neat, but not recomended :p
 
Curious to know why you want a separate 1000W unit for the base system and another 1000W for the graphics cards.

What kind of hardware do you have which would necessitate 2000W of power supply potential?

I've got a Seasonic X750 which is going to be more than enough for my IB system build in progress and still be enough for SLI or XFire if I ever go that route.
 
The only possible scenario I could see warranting 2000 watts of power is an SR-2 system with highly overclocked 6-core xeons on water, with 4 580s also highly overclocked on water.
 
There is a product "Juice Box" that is designed for this purpose. I know, I bought one but never found I needed it.
 
Also, if you are going to run this rig 24/7, you can just short the gpu psu to run constantly. You can do something like this-

With just a paper clip/piece of wire/etc. I'd probably spring for the $10 piece if I were you, but I have used a paper clip to jump psus before. Actually one time was to do what you are doing now, albeit just for testing purposes...
 
Im running two GTX 560's i was just wondering if this was possible as having a 1000w just laying around right now so i figured i just give it a whirl
 
sure its possible, and having less load on a psu is ok, but no way in hell 2 560Ti even with a heavily overclocked system need 1kw+ with any decent power supply, let alone 2x1kw, but to each thier own

1 power supply for system 1 for gpu and liquid cooler has been done and I know folks that do this, but honestly, both the Corsair and Enermax 1kw power supplies are far more then you "need" they are ample enough for GTX590 in quad sli :)
 
Two GTX 560s? If you want to do it for kicks, go ahead. Depending on your processor and how much it's overclocked, and how much your 560s are overclocked, you can run that with a 650-750 watt power supply.

First- check your breakers (brakers?). Having 2 1kw psus coming of of 1 outlet will likely pop a breaker, or disallow you from vacuuming that room while the computer is on. [/url]

And this is why power supplies are limited to ~1500W since after power loss in the supply is about all you can get from a standard 15A outlet.
 
You could just buy the 18ga wire needed and jumper it yourself. Save yourself a few bucks over the above and route the length of wire as needed.

You are jumping the green wire to any black wire to tell the PSU to turn on.
 
Although I have run dual supplies in the past at work, I would sell the 1000W supply and get a 1500W supply and call it a day.
 
I'd sell both and get a Corsair AX850 or Seasonic X850 at the most, as I feel 1000W let alone 2000W is just plain overkill.
 
Buy or borrow a Kill-A-Watt and measure how much your box is actually using, it may be way less than you think.
