Will my 450W power supply handle Asus Radeon R9 380 STRIX Gaming OC 2GB DCII?

[HappyTosh]

I suppose I have to upgrade to 550W...?
Here's the build:
ASUS B150I Pro Gaming/WiFi/Aura, S-1151
Fractal Define Nano S Black (140mm+120mm fan)
Intel Core i5-6400, Socket-LGA1151 (stock fan)
Kingston ValueRam DDR4 2133MHz 16GB (2x8gb)
Corsair CX450M, 450W PSU
500 GB SSD

- I think the PSU has the correct connector at least... I plan to do no overclocking.
When I tried the http://outervision.com/power-supply-calculator I got the feeling I would be fine, but reading posts here got me worried...

I do not think the Corsair CX will be any good I would go higher than 550 but its your choice

First off the Corsair CX PSU is a tier 4 unit and should be replaced regardless. Next a standard R9 380 recommends a 500w PSU, I would look for a 500W-550W PSU on this list http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html in the tier 1 or 2 category.

I would look at ether of these
