XPS 8940, C65R4 500w power supply
Hello, fellow PC enthusiasts,
I just wanted to ask a quick question. I have a Dell XPS 8940 with an Intel i7 10700 1TB NVMe M.2 drive and 128 GB of DDR4 RAM, I used to have a max 360w power supply that recently died. I have concluded that I will upgrade to a C65R4 500w power supply as I am upgrading my GPU to a GTX 1660 super and will need a more powerful PSU. I have the link to where I am potentially going to buy this new PSU but just wanted to ask if this one is the right one and will fit nicely, and work well with my XPS 8940. If you guys find any better deals for a 500w or better power supply that will fit inside an XPS 8940 without any modifications please let me know.
Have a good day!

Dell validated 500w psu for 8940 are
Y7R0X 500W Chicony
99TPH 500W Liteon
5K7J8 500W Delta
that list does not include
Note the Dell description is different for these too. the validated psu has MT in description, C65R4 is SFF.
btw the XPS Faq link for 8940 has gone bad

I think 7090 MT psu works for 7080 and 8940 too. it is just Dell did not validate it. Why Dell would design a new psu just for 7090 same 500w I do not know.
@DELL-Chris M can you send a list of DP/N of 260w psu for 7090 and 7080 tower. I would like to see if there are some same models in the two lists.
data sheet shows 7090 tower has 260, 300, 360, 500w
7080 has 260, 360, 500w
