I'm beginning research for a dual CPU, quad 980ti workstation. I will be 100% utilizing the graphics cards and CPUs quite frequently and for long periods of time. From what I can tell the juice I will need for this will require two power supplies. Do I have to get into splicing wires, or is there a cleaner way to do this? Can I plug the power supplies into the same outlet, or will that draw too much? Should the power supplies be identical? Below is my PCPP list at current, although I'd like to hear suggestions.

You should replace all those Corsair fans with some better ones as they are not really all that great.
They are not bad but they are not good either just sort of average.

If you dont care about looks there is the Noctua NF-A14 FLX 140mm fan.
There are other options as well.

Last that PSU is not bigh enough for that system so you should look at the 1200 watt or even the 1600 watt version.
And no you should avoid having two PSU´s in one system as its going to ruin your voltage regulation.

Well the single wasn't enough, if you look towards the bottom I have included a second one, so 2x 1000w.

Can you recommend a single PSU that can power this build?

And while I want to say looks aren't a priority, I've always had an aversion to those fans, can you recommend a second best?

There is a 2000 watt version of the Super Flower Leadex but thats for 240v regions only.
Not sure if a 1600 watt PSU can power all that.

As for fans check out what Be Quiet Phanteks and Noise Blocker.
Everyone and their moms says the Phanteks PH-F140SP are great fans, they just have one flaw and thats vibration noise when mounted in the top of a case.

yea I have the phanteks 140SPs, and have the same vibration issue from my top fans. Other than that they're great, but I'm also watercooled. Aren't these fans designed for pushing air through radiators?

As for the power supply, you're telling me not to run dual, is it a huge issue? But there isn't a single PSU that can run all this, so wat do?

No i am not telling you not to run dual i am just saying dont expect tight voltage regulation if you run two as its pretty much going to suck.
That is if you plan on using a Add2PSU adaptor.

Phanteks showed off a new PSU splitter at CES but i dont know if you can buy that yet or how good it is.
Really you have that problem with the Phanteks 140SP as well? i talked about it in the Phanteks clubs and the OP pretty much told me to stop trolling and get lost.

sorry you're going a little beyond my PSU knowledge....voltage regulation? Meaning the power to the cards is going to vary slightly? Would it help if I ran just the GPUs off one PSU, and the rest of the system off the other? I'll look into this phanteks buisness, thanks

EDIT: Meh, that looks about splitting one powerful psu into 2 smaller systems. http://www.phanteks.com/assets/manuals/PH-PWSPR_EN.pdf
