XPS 8940, 650W power supply?
I picked up a refurbished MSI GeForce RTX 3070 for my Dell XPS 8940 thinking they'd be compatible, as it says on Dell's website. Turns out, my power supply is very inadequate (360W). From what I've read, I can only upgrade this PC to a 500W PSU due to the pin count on the power supply connector. Anyone find a workaround for this? All the RTX 3070s I found require a minimum 650W PSU. Thanks in advance!

Wow! Thanks for the fast reply. Looks like two of those will actually work with my current PSU.
Thanks again.

@Ian Mag
You can install what is said above excluding the RTX 3080, Don't bother you will pull to much power off the PSU.
You can however also install the RTX 4060 ti 150-watt TDP
RTX 4070 200 Watts TDP, same as the RTX 3060 ti's TDP.
You can also install the RTX 4070 Super which is the same TDP at 220 Watts as the RTX 3070 that ships with it. (However, you need to use 1 6-pin to 8-pin adapter and the provided 16-pin for the GPU with the super.) Do not worry the extra 2 pins are sense pens, not power so it will not overload the secondary six pins since they are not power pins.
I would recommend PNY as they seem to work ok with Dell's UEFI so you can keep secure boot enabled.
