450W PSU sufficient for RX 580 or RX 590?

[jippiee]

My current setup is:

Ryzen 5 1500X

MSI B350 Motherboard

GTX 650 GPU

8 GB RAM

480 GB SSD

Corsair CX 450M PSU

 

I'm long overdue for a GPU upgrade and am considering a RX 580 or RX 590, preferably a Sapphire NITRO+.

My CPU has a TDP of 65W and the GPUs each have a TDP of 235W.

That is a total of 300W, so 150W left for motherboard, drives, fans etc.

 

Will my Corsair CX 450M be sufficient for this upgrade?

So according to this review the RX 590 consumes a peak of 239W in game, and the RX 580 has a peak of 208W.

So my CX 450M should still be capable for the RX 590, correct?
