Recommended PSU upgrade for XPS 8700?

Like a lot of folks, I bought a new video card (GTX 960) only to find the PSU insufficient to boot up and run the machine.

I had a Rosewill 870W PSU but it's far too large for the XPS 8700 case, it bumps against the DVD/Blu Ray drive so I bought a new one. A Corsair 750. 

On the chance this is also too large, does anyone have recommendations for PSU upgrades?

The stock PSU is fine for a GTX 960.  Secure Boot must be OFF , Legacy CSM and option roms must be ON.  

And Bios must be at least version A10.

Dell XPS 8700 System BIOS update "A11", Fixes: , Enhancements: "Support Win10 OS."
Dell XPS 8700 System BIOS update "A10", Fixes: "GTX900 Series Video Black Screen.", Enhancements: "Enhanced system usability."
Dell XPS 8700 System BIOS update "A08", Fixes: , Enhancements: "Enhance USB3.0 capabilities."

The A10 bios is here and on the XPS 8700 page here.

* Download/Save the file to the windows desktop
* Before running A10, I would install the prior Bios in order
* Disconnect any external hard drives, keys, printer, scanner, etc. You only want the USB mouse, USB keyboard, LAN, monitor connected
* Run the executable from Windows
* Allow the system to complete the installation and restart automatically. Do not force a restart or power off

NEW thread started to discuss XPS 8700 Nvidia GTX video card upgrades

Place holder for new thread to discuss XPS 8700 AMD video card upgrades
===============================

We and Nvidia are looking into the issue, but understand, we only "test/validate" those video cards in my list. Our warranty does not cover non-OEM video cards NOT on our list. Ultimately, it will be up to the XPS 8700 Team and our Legal Team to decide if Dell is going to allocate resources to fix an issue with non-validated, non-tested 3rd party hardware. All I can do is funnel the data to them. Below are the Dell validated/tested OEM video cards for the XPS 8700 and our 460w power supply =

My computer would not boot with the standard 450W PSU and GTX 960 installed. That's why I asked for recommendations for PSU upgrades.

are you on BIOS version A10?

did you plug in the PCIe power to the card?

the OEM PSU is fine with a GTX 960

The card I bought, GTX 960 isn't on that list as working with the standard 450W PSU. I've installed a new PSU and updated BIOS, so let's see what happens.
