Second power supplier

[Kamran]

Hello,

Is it possible to install second power supplier ?

If Yes, HOW???

Thanks...

Yes you can however I fail to see the point for a consumer level product unless you're running an X79 platform with quad SLI or Crossfire. I don't know the correct way however if I were to do it I would combine both of the either 7th or 19th pins - I can't remember which one is the PSU on pin - together so both PSU's start. That's about all there is to it really from what I'm thinking off.

I want to put additional PSU to my case... for more power...

is it possible...

Something like that...

Your case as well either needs to support it by default or be modded to. I still don't get why you'd want to..

Of course it is possible. You have an image of it. The question is, what do you need it for? You will need to mess about a bit with the 20 pin connector, and while it isn't the most complicated thing to do, it might just be unnecessary. You're better off getting a new PSU with a higher wattage (there are plenty with 1500+ W around these days, which is enough for four Titans on an X79 platform)

As said, all you need to do is get an adapter of some sort to jump start the second one as you turn the computer on. Power supplies just convert the 240v AC current to low-voltage DC current, it's not controlled via software or anything so adding a second one isn't a problem.

That said, be careful to balance the power usage between the two units if you do that. Because of how power supplies work, you need to have a certain amount of load on both the 12v and 5v rail, else you can get really high fluctuations of voltage if you just pull from the 12v rail exclusively. Estimating the wattage each component needs is also important, to know how to balance the units equally.

As everyone else said however, there's really no need for it. Even a dual-Xeon setup with dual Titans will be fine with a 1600w unit. Only time it might be useful would be for an extreme workstation/number crunching setup, but in that case it'll probably be easier to get multiple systems instead.

Yes it would work but I think for your second psu you would need to short the motherboard pins to start the psu. Corsair has a youtube video about testing your psu by shorting the pins: www.youtube.com/watch?v=5FWXgQSokF4
