AMD lists the RX 480 as having a "Typical" Board Power of 150W (http://www.amd.com/en-us/products/graphics/radeon-rx-series/radeon-rx-480). On a test conducted by TechPowerUp, it shows that the power consumption of the GPU alone would be: 177W (typical gaming) to 180W (peak gaming).

Assuming you have an i7-7600K at 4.5GHz, a test conducted by Bit-tech will show that your *possible* total (whole system including typical RAM, HDD, SSD, etc.) power consumption using an Asus Strix RX 480 OC would be at 263W.

RealHardTechX lists that a rig built around an RX 480 is "recommended" to have a PSU wattage of 500W.

Corsair makes several lines of varying quality (from the average VS series to the exceptional RMi/RMx, HX, and AX series). Antec makes PSUs ranging from average to good quality.

As long as you aren't trying to run a large number of additional components, 650 watts should be plenty.

Your initially-selected Corsair 650W is way too much of an overkill.

Depending on the exact model of the PSU, note that the wattage is just one of the factors in determining what PSU to select. A more important factor is the built quality, reliability, and safety of such PSU. Check out this PSU Tier List to get a general idea of how PSU's are categorized according to their quality based on expert reviews.

I would recommend any of the following good-quality PSU's as more than enough to run your PC (just select whichever is available in your location and whichever fits your budget at hand):

These PSUs are MORE than enough (large headroom):
Antec TP-550C
Antec EA550G
Antec EDG550
Corsair RM550x
Seasonic G-550
Seasonic S12G-550
EVGA SuperNOVA 550 G3
EVGA SuperNOVA 550 G2
EVGA SuperNOVA 550 GS

These PSUs are JUST enough (with still some considerable or slight amount of headroom):
Antec HCG-520M
Antec HCG-520
Seasonic S12II-520
Seasonic M12II-520 EVO
Sesonic S12G-450
Antec TP-450C
Seasonic G-450
