To answer your question, yes, a 450w psu is sufficient for your parts.
But, I have some suggestions about your prospective build.
1. The 9th gen processors will be available soon. If you can wait, you will get more for your money with one of them.
I expect the i7-9700K to be the best gaming chip. It has 8 cores and will oc past the 5.0 on current 8th gen processors.
2. Today, the i7-8700K is as good as it gets for gaming.
But, the i5-8600K will game just as well and allow you to budget more for the graphics card.
3. Your case is a nice one and has room for a 160mm cooler.
Cryorig H7 is a nice mid range cooler, but your build deserves better. The noctua NH-D15s is as good as it gets.
4. 32gb is likely overkill for a gaming build. A 4 stick ram kit will still run in dual channel mode. Better to buy a 2 x 16gb kit if you need 32gb; 2 x 8gb otherwise.
5. Consider buying a 500gb ssd and deferring on the hard drive. You can always add a hard drive later. You may well find out that you do not need a hard drive at all. I don't.
And... make that a m.2 ssd. It is about the size of a stick of gum and plugs into the motherboard. No wires or cables needed.
The pcie versions are a bit faster than the sata versions.
6. You could use a 450w psu for a GTX1060.
Since it is working ok, I would not worry much.
Here is a chart for other options:

EVGA power supplies vary in quality, and I think yours is not one of the good ones.
I would think of a 550-650w psu to avoid the hassle of rewiring later.
Seasonic focus is an excellent option.
