Dual PSU Setup

[King Dranzer]

Got a crazy build with 2000W+ power requirement. I wanted to know if I can use two PSUs in one PC. Never did that before. If I connect Motherboard, 2GPUs and SSDs to one PSU and remaining 2GPUs and HDDs to one PSU.

Had a look on workstation PSUs but especially the 2500w and 3000w PSUs available are of bad quality. So I was not comfortable to go with them.

Will it work or will I face any problems.

 

[Mr Kagouris]

Yes you can, you just need to use a 24pin splitter to connect both PSUs to the mobo. Everything else you can pretty much connect normally (although I'd advise against mixing the power cables for GPUs and such because a sudden PSU failure from one of the units could have some very adverse effects that way).

May I ask what hardware you're using that would require 2000W?

 

[SkittishGaming]

What Setup?

 

[King Dranzer]

What Setup?

I can give you the setup but the GPUs they are going for are not yet released. I can give you build with old GPUs

If I connect all GPUs to 1 PSU will it be better.

 

[Mr Kagouris]

If the GPUs are not released yet how are you making approximations about their power consumption?

Also, what I meant was that you shouldn't power one GPU off 2 power supplies and such, not that you should power ALL of them off a single PSU.

Exactly hehe

Here is the build they are planning on but with small changes. The things that will be changed is GPUs. They are waiting for launch of Quadro Pascals

This build is not for gaming it is a business workstation setup.

 

[King Dranzer]

Probably the Power consumption of Quadro Pascal will be similar to Quadro Maxwell.

This build is not for gaming it is a business workstation setup.

I think I just fainted.
WHY???????
a litlle bit overkill

 

[bradsctt]

What sort of workload will this system be running?

If you're really needing that much HDD storage I feel a separate workstation and server setup would be more suitable?

That would avoid the 2 PSU, 1 PC issue obviously, unless you specifically need all of this in the one system.

If you used a separate server, the workstation should be able to run on 1x 1600W

 

[Mr Kagouris]

I may be wrong but I get the feeling that you're not actually buying any of this and just wanted to see how overkill a system you could make up with PCPartPicker.

That said, this would run on an EVGA 1600 T2 just fine.

 

[King Dranzer]

That's true but they wanted single PC setup which can be connected to multiple laptops over WiFi. About their work they told me that they will be doing some graphical rendering and some CPU intensive work.

I wouldn't be buying stuff like that as I cannot afford it even in dreams.
But those people would. And for a business organization this is worth spending as I think this setup some how improves productivity of the organization which will bring them good profits.

I don't think EVGA 1600 T2 will be sufficient.

 

[King Dranzer]

If I get 2 Corsair AX1200i and connect GPUs to one PSU it and Connect the remaining components to another. Will it work.

 

[Mr Kagouris]

PSU 1 <---- GPU1, GPU2, both EPS, SSDs.
PSU 2 <---- GPU3, GPU4, HDDs.

I'm really thinking the Pascal Quadros will not require dual-PSU though.

It may be a good idea to look into what software the company will be using as even with workstation applications more cores =/= more performance.

But you advised above that mixing power cables for GPUs is not recommended and it will cause problem if 1PSU fails.

 

[Mr Kagouris]

No no, what I meant was to not connect any GPU to both PSUs. Connecting half the GPUs to one and the other half to the other is fine.

 

[King Dranzer]

Thank you guys for the help.

I recommended them to go with two Corsair AX1200i setup. They finalized it.

Thank you very much guys for the help. I know some people have done Dual PSU setup before even at some time I thought of trying it. But I was not sure of drawbacks of it or will it cause some major problem which it doesn't(know I know it).
