MSI R9 390 750W PSU recommended on box?

I've been receiving the parts for my build and I was looking at the back of the box of the MSI R9 390 GPU I ordered and it says recommends a "minimum" 750W PSU.

This worried me as I only purchased a 650W PSU. Should I think about returning the current PSU I have for one with more wattage?

PC Part Picker said 440W for my build, so I thought going with a 650W PSU would work just fine. I haven't build the system yet, so would still be easy to return the current PSU.

EDIT: Should note I do not plan on overclocking anything.

Here is my build below:

Your fine you bought a good quality PSU. They recommend high wattages to avoid problems because people tend to buy crap PSUs. Your fine though I've seen people run 390s on less.

You've got a good PSU. As Ksongs said, you'll be fine.

as others said

with that build you will have headroom even to overclock the 390... and that is an excellent pus made by seasonic.

750 is recomended for various reasons including efficiency and over clocking as well, but it is not the minimum. 650w is fine, just not as ideal in every way as a 750 might be. Ksongs reason is one of many why they up rate the recomended specs, but efficiency is a large reason also. Dont worry about it.

nice link.

and emphasis on minimum since many peple confuse that word with "recomended no matter what other variables there are" lol
