"I can now verify that the 500w Precision T3660 power supply is compatible with the Inspiron 3910. I Installed it in the case and it's an exact match to the size of the 300w supply the 3910 came with. (The system ... runs flawless on an RX 6650XT). "

"when it comes to a 4+4 you never have to plug in both if the board doesn't have the second plug. I can also say with confirmation (because I've tested it), that the 10 pin plug PSU for the XPS and Alienware will electrically work with the 3910 (8 pin socket) even though it won't fit in the case."
