so i have h55m-p31 motherboard and recently acquired R9 390 graphics card from MSI but when i plug it in mother board wont even post i mean no beep no bios nothing just black screen.

so i wonder if it's compatible with this motherboard because i had similar problem with this motherboard when i tried to install new RAM same thing happened
 
Solution
Try to use 6 and 8 from diffirent cables not same.Soo one is 6 the other is 8.

R9 380 requires 30A soo your psu on single rail can give around 26A (Maximum) soo try as i said in up.
