what powersupply does it have?
amazing english skills btw.
Well, being sarcastic is fine i dont think they have anything against itYou've probably broken the rules of the site with your sarcastic comment about the OP's English, English may not be their first language. So a stupid and crass comment there, which the mods may well pick up on. Because you were clearly being sarcastic, no point denying it.
Shame, because you actually asked the right question. Hopefully the OP actually comes back and answers, but I wouldn't blame them if they didn't.

But, i think you're right and joking about someones english skills is kinda bad.
so, sorry op.
I probably wouldn't take my chances on an RX card unless you can verify that someone else has done it on an Optiplex 390. VESA mode 103
A GTX1050Ti or GTX1060 would have a much higher probability of being compatible.
