Can this PSU run this build?

I wasn't sure if 650W is enough because on the PCPartPicker it says 487W and I don't know if 650W allows enough.

It should be fine. And by should I mean that usually for a single gpu a 550w is great. The 390 though seems to be a little peculiar though. There have been some cases where some older psu had problems with the card. The EVGA GS though is a great power supply and i think it is going to be ok.

A 650w is what is recommended for a R9 390 GPU, if you want some cushion get a 700w. You should be okay.

A high quality psu can handle what it is rated to handle, 650W is 650W. Only when you buy low end power supplies should you worry about that.

The build itself under gaming loads will probably draw no more than 350 watts, probably less. In order to really hit that 450W mark both the CPU and GPU need to be at 100% load the entire time, doubtful.

That power supply is a perfect fit for your specs , and a very very good one made by SEASONIC.

Here is Guru3D's power supply recommendation:

AMD R9 390 and 390X - On your average system the card requires you to have a 550~600 Watt power supply unit.
AMD R9 390 and 390X Crossfire - On your average system the cards require you to have a 800 Watt power supply unit as minimum.

If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina.

Might wanna consider this as a less expensive and better performing alternative
