I have an Optiplex 390 SFF with an i5-2400 and 8 GB RAM (2 x 4GB).​

Can I install a low-profile RX 550 in it? Is it compatible? What other options should I consider?​

Where do you get information about how much power is supplied by the PCIe slots?
Put into Google: Optiplex 390 SFF Then, one of the results (for me, the very 1st one), has technical *.pdf that you can download. Named as "Optiplex-390-Technical-Guidebook- ...". Download that *.pdf, open it, scroll to page 16 and read the Maximum Wattage specs of PCI-E x16 slot.
That's how.

Also, do note that OP has SFF version of it, limited to 25W. DT is also limited to 25W while MT is limited to 75W.
